Compounds

High-performance elastomers have the ability to withstand rather extreme ambient conditions, including heat, chemicals and solvents. The following is a list of compounds that are currently available from HEXPOL:

FFKM — provides resistance to very high temperatures and extreme chemical environments, while still maintaining elastomeric sealing capabilities. These materials are utilized in the aerospace, chemical processing, semiconductor, and automotive industries.  Some applications include O-rings, gaskets, profiles, tubes and other parts that require long term sealing reliability.

FKM — Synthetic elastomers are designed to withstand very high temperature environments.  FKM also provides extraordinary levels of resistance to chemical, heat and oil while providing useful service life above 200°C.  This elastomer is used in the automotive, appliance, and chemical industries. Applications include sealing systems (o-rings and shaft seals) and hydraulic drivelines.

Urethane — is used in hundreds of applications in multiple industries and is easy to use and has good wear resistance. Properties include hardeners, fatigue shear and abrasion resistance.  Excels in mechanical strength, has low heat resistance and chemical resistance.  Urethane is also well suited for production casting of concrete, gypsum and wax. Seals and extrusions.

AEM (Ethylene-Acrylic or AEM) — used in applications  where heat and chemical resistance, and specific rubber-like qualities are needed, including automotive powertrains.  Other applications include automotive air ducts and turbocharger hose (largely popular because all cars include a turbocharger now), auto connectors, cable insulation and jacketing, and seals and gaskets. 

T (Polysulfide) — is a synthetic polymer made by the reaction of sodium polysulfide with an oxygen dichloride resistant to light (UV), oxygen, oil, and solvents impermeable to gases. Other properties include low temperature flexibility and flex-crack resistance. Applications include rubberizing fuel storage tanks and in manufacturing of oil and gasoline-resistant tubing and gas light diaphragms for gas meters.

ECO (Epichlorohydrin) — ECO is broadly used in auto fuel hose, air ducts, A/C and vibration damping.  Its electrical properties benefit laser printer rolls.  It also offers excellent performance in high and low temperatures and has low gas permeability.  ECO offers good resistance to bio-fuel and abrasion.

CSM (Chlorosulfinated Polyethylene) — CSM is very resistant to attach by oxygen and ozone and properly compounded is excellent weathering resistance.  Also, high textile strength and can be formulated for excellent weathering resistance, abrasion resistance and resistance to abrasive chemicals.  CSM is also flame retardant, coherent to high temperature of moderately high temperature, has moderate oil resistance and good cold flex properties.

CPE (Chlorinated Polyethylene) — has excellent physical and mechanical properties such as resistant to oil, chemicals, and improved thermal properties.  Also, CPE has better compression set, flame retardancy, tensile strength and abrasion resistance.  Applications include wire and cable jacketing, roofing, automotive and industrial hose and tubing, molding and extrusion.  CPE blends well with many types of plastic such as Polyethylene, EVA, and PVC.  

HNBR — hydrogenated nitrile (HNBR) is a tough and durable elastomer.  HNBR is used for applications requiring high and low temperature performance (fuel resistance and cold temp resistance set it above normal NBR).  It is ideal for seals that are in contact with oil fluid components and rolls for paper mills.

ACM (Polyacrylate) — offers significant improvements in long-term high-temperatures compared to another elastomer fueling.  It is used in automotive applications including valve cover gaskets, oil pan gaskets, rocker cover gaskets and various seals.  Also, the extensive heat and oil resistance make ACM ideal for solvent-based adhesives, calk and sealant applications.
