The most frequent used base of polymers’ compounds are natural rubbers, which general characteristics is shown below:
Lp. | Scientific name | Sign in ASTM | Thermal resistance[C] | 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. | Building industry, automotive industry and used as a base to rubber glue production |
5. | Ethylene Propylene Rubber | EPDM | - 40 do + 130 | Excellent resistance to heat, water, steam, ozone and UV light while providing very good low temperature flexibility properties, withstand the effects of brake fluids, alkali, mild acidic and oxygenated solvent environments. | Building industry- to seal windows and doors, automotive and chemical industry |
6. | Fluorocarbon Rubber | FKM | - 20 do + 250 | Excellent resistance in harsh chemical and ozone environment, excellent service in oil, gasoline, hydraulic fluids and extended fuels with thermal stability to 250°C. | Aircraft, automotive, chemical industry, is used in rocket’s technology and in other industry branches as well. |
