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, 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.

FLUOROELASTOMERS
 
(Vitonâ„¢) (ASTM Designation: FKM)

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.

NITRILE: ACRYLONITRILE-BUTADIENE RUBBER (NBR), BUNA-N

Nitrile rubber is best suited for applications where resistance to oil, fuel and chemicals is required. NBR is commonly used for industrial and automotive applications, in products such as fuel and oil handling hoses, seals, grommets, hydraulic hoses, and o-rings. It can stand up to temperatures ranging from -40ºC to + 125ºC and is typically available in a durometer range of between 40 and 90.

Nitrile can also be compounded with carboxylic acid groups to create XNBR or Carboxylated Nitrile, which has a greater abrasion resistance as well as more tensile and tear strength. Nitrile rubber can also be hydrogenated to create (HNBR), a rubber with greater physical strength and minimal degradation over time.

HYPALON: CHLOROSULFONATED POLYETHYLENE
 
Chlorosulfonated Polyethylene Hypalon has outstanding resistance to most chemicals, heat and oil are among the most important characteristics. 
Further, HYPALON is flame resistant, offers excellent color stability, weather and abrasion resistance. Low moisture absorption, good dielectric qualities, and high abrasion resistance are among its other features.

Like most synthetics, HYPALON® is superior to NATURAL RUBBER in temperature, oil and resistance to the effect of ozone.  HYPALON is generally attacked by concentrated oxidizing acids, esters, ketones, chlorinated, aromatic and nitro hydrocarbons.

EDPM

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 withstnad significant temperature fluctuations (-50°C + 160°C)

NEOPRENE

POLYCHLOROPRENE (CR), CHLOROPRENE RUBBER
Neoprene is characterised by its versatility. It has good mechanical strength, it is ozone and weather resistant, and has good aging resistance. It also not very flammable, bonds well to metal and has a good resistance to certain chemicals. Typical service temperature is between -40ºC and +135ºC and it is available in durometers ranging from 30 to 95. Neoprene can be formulated for use in mass transit industries due to its ability to meet ASTM c1166, e162, e662 and SMP800C standards.
