MonoMethyl Aniline (MMA) is also known as aniline oil, methylaniline, aniline monomethyl ether and aniline dimethyl ether. It is a colorless liquid with an aromatic odor that is used in various industries including agriculture, dyes, plastics and rubber.
When rubber is exposed to MMA, the rubber can become brittle and crack due to the hardening of the rubber caused by the chemical reaction of MMA with rubber. Over time, the rubber can become dry and brittle, and even begin to flake off. Additionally, swelling and softening of the rubber may also occur. If left unchecked, the rubber can become too soft, leading to cracking and ultimate failure.
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.
