Methyl ether, also known as methyl chloride, is a colorless, volatile, flammable liquid with a sweet odor. It is commonly used as a solvent in the production of paints, varnishes, pharmaceuticals, and adhesives. It is also used in the manufacture of rubber products, as a refrigerant, and in the production of various chemicals.
When rubber is exposed to methyl ether, the most common types of failures are swelling, softening, and cracking. Swelling can cause the rubber to stretch and deform, which affects its ability to seal properly. Softening may cause the rubber to become brittle and crack, resulting in leakage. Finally, cracking can occur due to embrittlement, which is caused by the chemical reaction of the rubber with the methyl ether.
Fluorosilicone o-rings are a hybrid of silicone and FKM resulting in great jet fuel resistance with high and low temperature performance. Also widely used in semiconductor Ashing equipment with strong resistance to oxygen plasma, FVMQ fluorosilicone o-rings also feature excellent flexibility, compression resistance, aging and sunlight resistance, and overall wide range of basic chemical resistance.
