Silicone Polymer
Methyl Vinyl Silicone (VMQ) and Methyl Phenyl Vinyl Silicone (PVMQ) are semi-organic elastomers with outstanding resistance to extremes of temperatures. Silicone can provide reliable service at temperatures as low as -175ºF (115ºC) to as high as 480ºF (250ºC) continuously. It also has good resistance to compression set.

Most silicone is non-toxic; therefore grades are available for food processing, use with milk and edible oils, and for use in medical devices including grades for long and short term bodily implantation. Specialty grades are available for static dissipation and fire retardation.

Low physical strength and poor abrasion resistance combined with high friction, generally limit silicone to static seals. Although it swells considerably in petroleum lubricants, this is not usually detrimental in most static sealing applications.

PAI offers silicone compounds in a hardness range of 20 to 80 durometer. Salmon or orange is our standard color, but a rainbow of other colors is available. Translucent and clear compounds are possible too.
