Fabricated rubber parts available in silicone, viton, EPDM, neoprene & more

Fabricated Silicone Parts

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, and can be color matched to any Pantone/RAL. Silicone also has high tear and tensile strength, good elongation, great flexibility and a durometer range of 20 to 90 Shore A.

Silicone rubber resists the deteriorating effects of sunlight, ozone, and gasses which cause weathering. Inherently water repellent (hydrophobic), silicone is not affected by moist operating conditions. Very dry conditions and low humidity will not leach, dry out, or affect silicone in any way. Silicone also resists the deteriorating effects of the agents found in rain water: nitrates, sulfates, chloride, and hydrogen ions. Surface water containing minerals, acids, bases, and salts from the soil normally have no detrimental effect on silicone.

It can be formulated to meet a far reaching range of specifications, such as FDA, NSF, Mass transit specs (SMP 800c), UL 94 V0, MIL & AMS specs and many more. There are a few caveats though. Silicones should not be used with concentrated acids, alkalines or solvents.

Fabricated FluorElastomers (Viton)

The more common FluoroElastomers used and specified in various applications are Viton® (Dupont Elastomers) & Dyneon® (3M, also previously known as Fluorel®)

FluoroElastomers offers the widest range of fluid and chemical resistance of any commercial rubber. Excellent resistance to oils, fuels, lubricants and most mineral acids, this high performance synthetic rubber also has excellent temperature resistance, -10° to 400°F (-20° to 205°C) continuously.

Standard durometers are from 50-90 Shore A. Special formulations can have your FKM seal meeting standard low temperatures as low as -25°F or as high as 550°F. (-30°C to 290°C)

Whether your application is aerospace, chemical processing or any number of other industrial applications, there is a particular type of Fluoroelastomer that best suits your specific performance requirements. The general purpose types differ from the specialty types primarily in terms of chemical resistance.

In the specialty family, the choice remains mostly between four types that are tailored for superior fluid resistance, low-temperature performance or combinations of these properties. Special care must be taken when requesting a Fluoroelastomer for your application due to the large variances in performance engineered compounds.

Fabricated EPDM: Ethylene Propylene Diene Monomer

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 (-50ºC to +160ºC).

It exhibits extremely low temperature flexibility and can resist temperatures of up to 160ºC with peroxide curing. It is typically available in a durometer range of between 40 and 90. While it is quite resistant to abrasions, and compression set, EPDM has a very poor resistance to oil.

Fabricated part - Polyurethane and Plastics

Fabricated Polyurethane and plastics

Polyurethane, Nylon, Teflon, UHMW, Graphite & Phenolics

Polyurethane's most unique characteristic is its extremely broad range of hardness. It can be soft as an eraser or hard as a bowling ball. It is also one of the toughest flexible materials available, in terms of tear, tensile and abrasion resistance. It also has excellent low temperature resistance (-40°C). It is, however, limited in the higher temperature range to approximately 90°C (195°F)
