CAMPHOR Resistant O-Rings and Seals
Camphene, also known as camphor, is a cyclic hydrocarbon typically found in turpentine and has a variety of applications. It is widely used as a fragrance, flavor, and preservative in the food and cosmetic industries, and is also used as an insect repellent. Camphene is also used in the production of plasticizers, resins, and synthetic camphor, and as a solvent in paints, oils, and varnishes.
Rubber tends to be susceptible to swelling, cracking, and hardening when exposed to camphene. The chemical's ability to break down rubber compounds can weaken the material, leading to a reduction in sealing performance. Ozone, weathering, and extended exposure to camphene can all lead to an accelerated breakdown of the rubber's molecular structure, resulting in a loss of elasticity and integrity.
Buna-N (NBR, Nitrile, Buna)
Buna-N o-rings also referred to as NBR o-rings and Nitrile o-rings are the most widely used o-ring material in the word because of low cost, good mechanical performance with resistance to water, most basic oils, lubricants and some fuels, many pneumatic, hydraulic systems, and the default choice for basic applications. Buna-N o-rings are not recommended for exposure to sunlight, UV light, ozone and general outdoor weathering or hash chemicals, acids, keytones and many others.
