Silicone
- More info -

Silicone

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
- More info -

EPDM

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
- More info -

Neoprene

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
- More info -

Fluorosilicone

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
- More info -

Natural rubber

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.
