Here is a quick and easy way for designers engineers, component specifiers and purchasing professionals to identify the rubber material best suited to your application. We also welcome you to contact one of our experts to further validate your results or discuss what material could be the best choice in line with your application requirements and business criteria.
Silicone is one of the most versatile of "rubber" compounds. With its extreme temperature range (-80°F to 550°F), it exceeds all comparable materials in their insulating properties as well as flexibility in a wide range of electrical applications. It is non-conductive, maintains dielectric strength (can be formulated to be conductive), and can be color matched to any Pantone/RAL.

EPDM is one of the most widely used synthetic rubbers. It can be found in several industries ranging from automotive to HVAC (heating, ventilation and air conditioning). This is due mainly to its excellent resistance to water, steam, oxidation, ozone, acids and alkalis, as well as its ability to withstand significant temperature fluctuations (-60ºF to +150ºF).

Neoprene is characterized by its versatility. It has good mechanical strength, it is ozone and weather resistant, and has good aging resistance. It bonds well to metal and has a good resistance to certain chemicals. Neoprene is also self-extinguishing and can be formulated for use in mass transit industries due to its ability to meet ASTM c1166, e162, e662 and SMP800C standards.

Fluorosilicone rubber is an inorganic "hybrid" elastomer which combines the wide temperature range spectrum of silicone with some of the chemical resistance of fluorocarbon rubber. Due to its silicone base, fluorosilicones have relatively low tear strength, abrasion resistance, and tensile strength, and therefore, are generally not suited to dynamic applications.

Natural rubber is fairly easy to process. It has good low temperature properties, excellent elongation and a high resistance to tears and abrasions. Its useful temperature range is between -60ºF and + 170ºF, and it can be easily bonded to metal. Unfortunately natural rubber exhibits poor resistance to ozone, oxygen, sunlight, solvents and oils.
