Rubber Elastomers

Our technical staff has a working knowledge and the capabilities to formulate rubber compounds from any of the following elastomer groups. We do not stock sheet goods in most of these elastomer types but we do have existing formulas or can custom compound a material to fit your needs for purchase in uncured, slab form.

In house compounding allows Mosites Rubber Company to keep up to date with the latest advancements in polymer chemistry and compounding technology. A continuous effort is made to improve our product line to serve the every changing needs of industry.

The following information is general to each type of elastomer. Compound variation can result in materials that perform above or below these listed standards. Please call with information specific to your application for an elastomer recommendation.

Good resistance to alcohol, amines, petroleum oils, and gasoline's over a wide range of temperatures. Also good resistance to caustic salts. Fair acid resistance. Poor in strong oxidizing agents, chlorinated hydrocarbons, ketones, and esters. Temperature Range -65°F to +250°F

Good resistance to strong acids, salts, alkali's and chlorine solutions. Good resistance to weathering, sunlight and ozone. Has long service life at temperatures up to +300°F. Poor oil resistance. Temperature Range -30°F to +300°F

Good in moderate acid, alkali and salt solutions. Resistant to commercial oils and fuels. Poor in chromic and nitric acids, aromatics and chlorinated hydrocarbons. Temperature Range 0°F to +175°F

Chlorinated Polyethylene 
Good chemical and caustic resistance. Temperature Range -20°F to +275°F

Chlorosulfonated Polyethylene
