Thomas A. Caserta, Inc. can supply any material to meet specific requirements such as physical properties, colors, or finish. This is a list of the most commonly used materials:

EPDM - Excellent weatherability, good high and low temperature resistance, low gas permeability. Resistant to ozone, steam, water, alcohols, brake fluids. Poor resistance to petroleum oils, diester lubricants. Temperature range: -60°F to 280°F

Neoprene - Good general purpose elastomer, with moderate oil, ozone and water resistance. Resistant to freons, high analine points oils, mild acids. Not recommended for phosphate esters, ketones, brake fluids. Temperature range: -65°F to 260°F

Nitrile - Excellent resistance to petroleum products, excellent compression set; resistant to oil, water, silicone greases and oils. Not recommended for halogenated hydrocarbons, ketones, ozone and sunlight. Temperature Range: -65°F to 275°F

SBR - General purpose elastomer, good adhesion to various substrates, good abrasion resistance, good resiliance. Resistant to brake fluids, alcohols, water. Not recommended for solvents, oil/gas, sunlight. Temperature range: -65°F to 225°F

Silicone - Best overall temperature range of elastomers currently available. Excellent resistance to dry heat, as well as, resistance to low temperature, brake fluids, high analine point oils. Not recommended for some dynamic applications due to poor tensile strength and tear. Poor in petroleum oils and ketones. Temperature range: -150° to 500°F.

Viton® - Outstanding resistance to the effects of heat, chemicals, and solvents. Viton® has good tensile, resistance and low compression set. Limitations include poor low-temperature properties, limited hot-water resistance and shrinkage. Temperature range: -50° to 600°F.
