Silicone rubbers are high molecular organosilicon polymers, with very good resistance to high and low temperatures. They also have good dielectric properties, low compression set, very good resistance to oxygen and ozone. In relation to other elastomers at room temperature, they are characterized by higher permeability gases, they are non-flammable. Silicone gaskets are not recommended to work in motion, because they show a low tensile strength and low tear and abrasion resistance.

Operating temperature range is from -60 to +200°C, for short duration increases to 230°C.

Silicone vulcanizates are resistant to:

• mineral oils and greases
• dilute salt solutions
• alcohols
• the water to 100°C
• Conditionally resistant to non-flammable hydraulic fluids HSD

Silicone vulcanizates are not resistant to:

• concentrated acids and alkalis
• esters and ethers
• aliphatic and aromatic hydrocarbons
• steam of over 100°C
