Advantages

Appliance

1. Natural Rubber and Synthetic Polyisopropene NR
IR
- 50 do + 80 Outstanding resilience, resistance to tear and abrasion, excellent elasticity, flex fatigue resistance, resistance to alkali and acidic solvent. General purpose rubber, medical articles, plugs, sheets, working details f. ex. Amortizators
2. Styrene Butadiene Rubber SBR - 40 do + 100 Very good flex fatigue resistance, resistance to many polar type chemicals such as alcohols and ketones General purpose elastomer is used to replace or to be mixed with NR.
3. Acrylinitryle Butadiene Rubber NBR - 30 do + 120 Resistance to hydraulic fluids, lubricating oils and other non-polar petroleum based products due to the polar structure of this elastomer, resistance to air and water environment.

Automotive, aircraft, chemical industry

Seals of mechanic tools, servomotors and so on.
4. Polychloroprene CR - 30 do + 100 Excellent aging characteristics in onone and weather environment, along with abrasion and flex racking resistance, resistance to alkali and acids, flame retardant and suitable for petroleum based oils, excellent adhesion to metal.
