The Viton® A is a fluoroelastomer dipolymer comprised of vinylidene fluoride and hexafluropropylene. Provides good chemical resistance to petroleum products and solvents. Avoid polar solvents, amines, anhydrous ammonia, hydrazine and hot acids.

Features of Viton:

• ASTM D1418: FKM (FPM)
• Temperature range: -26 to 204 °C
• Durometer: 75
• Resistance to compression set: 1
• Color: Black

Silicone - a group of elastomeric materials made from Silicone, Hydrogen and Carbon. Excellent material for extreme temperatures. Very good with ozone and UV radiation. Avoid chlorinated solvents, aliphatic and aromatic hydrocarbons and petroleum oils. Silicone is generally permeable to gases.

Features of Silicone:

• ASTM D1418 VMQ
• Temperature range: -115 to 200 °C
• Durometer: 70
• Resistance to compression set: 2
• Color: Red

Buna-N - a copolymer of Butadiene and Acrylonitrile. Also know as nitrile rubber and is a synthetic blend of acrylonitrile and butadiene. Generally resists fuels and oils. Avoid highly polar solvents such as acetone, MEK, etc.. and direct exposure to ozone and sunlight.

Features of Buna-N:

• ASTM D1418 XNBR
• Temperature range: -40 to 120 °C
• Durometer: 70
• Resistance to compression set: 2
• Color: Black or Brown

FETFE® - a fluoroelastomer with special TFE Additives. An ACE Glass exclusive fluoroelastomer compound with TFE additives. It has good compression set along with good temperature and chemical compatibility.

Features of FETFE:

• FKM + PTFE as an internal lubricant
• Temperature range: -18 to 204 °C
• Durometer: 70
• Resistance to compression set: 2
• Color: Generally Black
