But which option is actually the best fit for your application?<\/span><\/p>\n<p><span style=\"font-weight: 400;\">One of the primary options is <a href=\"https:\/\/www.marcorubber.com\/silicone-o-rings.htm\">silicone<\/a>, so let\u2019s find out if it is the solution for which you have been looking.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Silicone is an inorganic, common synthetic polymer. The <\/span><a href=\"https:\/\/www.shinetsusilicone-global.com\/info\/begin1.shtml\"><span style=\"font-weight: 400;\">family \u201csilicone\u201d<\/span><\/a><span style=\"font-weight: 400;\"> refers to a number of polymers made up of repeating units of siloxane. Siloxane\u2019s main chain is essentially a pattern of alternating silicon(Si) and oxygen(O) atoms.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Silicone is very versatile and offers a number of benefits including resistance to:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">extreme temperatures, including heat and cold (-75\u00b0 to 450\u00b0F),<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">ozone,<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">UV,<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">weather,\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">chemical,<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">oil,<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">water steam,<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">and corona discharge.<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">Silicone is also suitable for use with both acids and alkalis.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">One of the amazing features of silicone is its ability to be morphed to fit many situations. For example, Marco Rubber offers silicone products suitable for a wide range of specialty applications and industries. We have compounds for almost every need, such as:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Flame retardant grades.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Electrically conductive materials.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Extreme high and low temperature grades.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Platinum cured formulations.<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">We often develop formulations uniquely designed to meet individual customer specifications, but more on that later. As a baseline, we offer a wide range of silicone forms to fit almost any application, including:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">compression molding and injection molding using liquid silicone rubber (LSR) or <a href=\"https:\/\/www.marcorubber.com\/high-temperature-seals\">high temperature<\/a> vulcanized (HTV),<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">solid silicone rubber extrusions,<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">and expanded closed-cell silicone rubber extrusions (also known as silicone sponge or foam).<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">What form of silicone will work best for your organization will depend on your industry and applications. Let\u2019s take a deeper look at some industries that commonly use silicone.\u00a0<\/span><\/p>\n<h2><span style=\"font-weight: 400;\">Medical &amp; Pharmaceutical<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">One of the most important components of the medical and pharmaceutical industry is cleanliness in accordance with regulatory compliance. We offer silicone compounds that are USP Class VI compliant and are, therefore, suitable for use when the product comes in contact with humans.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Our supply chain includes an ISO Class 7 and Class 8 clean room according to <\/span><a href=\"https:\/\/www.iso.org\/standard\/53393.html\"><span style=\"font-weight: 400;\">ISO 14644-2:2015<\/span><\/a><span style=\"font-weight: 400;\"> standards.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Silicone can also be adjusted to many scenarios beyond essential regulatory requirements. For instance, our silicone team once developed a formulation to satisfy very specific biocompatibility testing requirements that went beyond USP Class VI guidelines.\u00a0<\/span><\/p>\n<h2><span style=\"font-weight: 400;\">Food &amp; Beverage<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Silicone can be FDA 21 CFR <\/span><span style=\"font-weight: 400;\">Section 177.2600 compliant and, thus, <a href=\"https:\/\/www.marcorubber.com\/fda-o-rings-food-grade.htm\">suitable for contact with food<\/a>.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">This incredible material is also an excellent choice for those in the dairy and agriculture industry. Silicone can be made into extreme high tear resistant tubing. This tubing has an ultrasmooth inner surface with antimicrobial properties that inhibits growth of harmful bacteria.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">We also offer formulations suitable for NSF submission. For example, we have silicone formulations that meet NSF-61 standards for potable water systems for public use and consumption.<\/span><\/p>\n<h2><span style=\"font-weight: 400;\">Automotive<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">The automotive industry also faces a large number of strict regulatory requirements to keep end users safe and protect the company from recalls. Our silicone comes in ASTM D2000 FC \/ FE \/ GE compliant compounds.\u00a0<\/span><\/p>\n<h2><span style=\"font-weight: 400;\">Aviation, Space, &amp; Defense Industries<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Silicone compounds can meet Aeronautical Material Specification (AMS) standards for heat and weather\/environmental resistance for silicone rubber, including SAE-AMS-3302 \/ 3303 \/ 3304 \/ 3305.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">When it comes to specific accreditation, such as Boeing BMS 1-60 and Airbus ABD0031, silicone compounds can also be suitable.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Silicone is low-weight, non-flammable with self-extinguishing silicone sponge or foam. With high heat-resistant properties, silicone is suitable for a number of aviation, space, and defense applications.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Moreover, if you work with Marco Rubber we can provide full material certification for other <a href=\"https:\/\/www.marcorubber.com\/o-ring-mil-specs-chart.htm\">aerospace MIL spec standards<\/a>.<\/span><\/p>\n<h2><span style=\"font-weight: 400;\">Rail Industry<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">The rail industry requires flame retardant or self-extinguishing and low smoke, low toxic fume formulations for both solid and silicone sponge. Good news: we make that simple.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">We also offer compounds that are compliant with EN45545-2 (European fire safe materials standard), UL94V-0 (US fire standard), and NFPA 130 (US flame and smoke standard specifically for the rail industry).<\/span><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-large wp-image-363\" src=\"https:\/\/blog.marcorubber.com\/wp-content\/uploads\/2024\/03\/Marco_March_MCC2-1024x768.jpg\" alt=\"\" width=\"800\" height=\"600\" srcset=\"https:\/\/blog.marcorubber.com\/wp-content\/uploads\/2024\/03\/Marco_March_MCC2-1024x768.jpg 1024w, https:\/\/blog.marcorubber.com\/wp-content\/uploads\/2024\/03\/Marco_March_MCC2-300x225.jpg 300w, https:\/\/blog.marcorubber.com\/wp-content\/uploads\/2024\/03\/Marco_March_MCC2-768x576.jpg 768w, https:\/\/blog.marcorubber.com\/wp-content\/uploads\/2024\/03\/Marco_March_MCC2-1536x1152.jpg 1536w, https:\/\/blog.marcorubber.com\/wp-content\/uploads\/2024\/03\/Marco_March_MCC2-2048x1536.jpg 2048w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\" \/><\/p>\n<h2><span style=\"font-weight: 400;\">Is Silicone Right for You?<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">As demonstrated, silicone is a widely versatile material that can be used in many applications while meeting applicable regulatory requirements.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">There are a few instances where silicone would not be right for your application. For example, silicone would not be right for you if you need:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">high tensile strength,<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">high tear resistance,<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">high dynamic resistance,<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">high abrasion resistance,<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">use with fuels or petroleum-based oils,\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">or high impermeability.<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">But we believe there is one key factor to consider when deciding if silicone is right for you or not: <\/span><a href=\"https:\/\/www.marcorubber.com\/blog\/your-complete-guide-to-choosing-an-o-ring-supplier\/\"><span style=\"font-weight: 400;\">the manufacturer<\/span><\/a><span style=\"font-weight: 400;\">.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Your silicone manufacturer will make or break the experience of using silicone. They will be able to provide you with needed documentation for applicable regulatory requirements. They will help you identify appropriate sizing or creative solutions. They will be able to help you develop a specialized or custom solution for harsh sealing applications.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">For example, when a customer was developing a new design of an aircraft water valve, they came to us. They needed a diaphragm that was dimensionally stable but flexible and FDA compliant. Originally, they had worked with a traditional fabric reinforced material, but it was too stiff for the desired functional performance.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">So we went to work.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">We proposed a fiber-reinforced, FDA compliant nitrile rubber material. With some additional design modifications, the resulting diaphragm performed for over 10 years.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">That\u2019s the difference when you work with a collaborative partner invested in your success.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Don\u2019t settle for less: work with Marco Rubber.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">We are always expanding to bring more solutions and more experts into the fold to provide top-of-the-line and innovative solutions to our customers.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Is Marco right for you? <\/span><a href=\"https:\/\/www.marcorubber.com\/inquiry-quote.htm\"><span style=\"font-weight: 400;\">Let\u2019s chat and find out.<\/span><\/a><\/p>\n<h3>Related Pages<\/h3>\n<ul>\n<li><a href=\"https:\/\/www.marcorubber.com\/silicone-o-rings.htm\">Silicone O-Rings<\/a><\/li>\n<li><a href=\"https:\/\/www.marcorubber.com\/fda-o-rings-food-grade.htm\">FDA-approved O-Rings<\/a><\/li>\n<li><a href=\"https:\/\/www.marcorubber.com\/o-ring-mil-specs-chart.htm\">Aerospace &amp; military-approved O-Rings<\/a><\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>Is a Silicone Seal Right for Your Application?
