KLINGERlastic Elastomers - NR, NBR, FPM, EPDM, SBR, CR, VMQ, IIR, CSM

Supplier: Klinger Limited

Elastomeric sheet compounds mark the entry level to Klinger's sheet-sealing range of products.

Price Guide: POA

Consisting of base polymers, vulcanising agents, fillers and various additives, elastomeric gaskets offer effective, low sealing stress seals typically for low temperature, low pressure applications.

Natural rubber exhibits exceptional elongation, tear strength and recovery properties. It has poor resistance to ozone, oxygen and sunlight weathering. Natural rubber has high wear and abrasion resistance. The material is suitable for moderate acids, alkalis, salt solutions, petroleum and solvents. It is considered unsuitable for use with strong acids, fats, greases and most hydrocarbons. Temperature range -50 to 120 deg C

Nitrile is a synthetic rubber offering improved chemical resistance and temperature capabilities to neoprene. The material offers good resistance to oils and solvents, aromatic and aliphatic hydrocarbons, petroleum oils and gasolines, animal fats and lacquer solvents. It offers poor resistance to strong oxidising agents, chlorinated hydrocarbons, ketones and esters. Temperature range -50 to 120 deg C

Viton (Fluorinated Hydrocarbon) offers excellent resistance to acids, aliphatic hydrocarbons, oils gasoline and many industrial applications. The material offers excellent resistance to temperature, weathering and gas permeability. It is not suitable for use against amines, esters, ketones, steam or low temperature service. Temperature range -30 to 200 deg C

EPDM offers good resistance to ozone, heat, steam, strong acids and alkalis. It is not suitable for use in oils, solvents and aromatic hydrocarbons. Temperature range -50 to 150 deg C

SBR synthetic rubber offers excellent abrasion resistance and is suitable for use with weak organic acids and moderate chemicals. It is unsuitable for use with ozone, strong acids and most carbon hydrocarbons. Temperature range -50 to 120 deg C

Neoprene has good resistance to aging, ozone and weathering. It also has good physical properties and resilience. It is resistant to a range of dilute chemicals and mineral oils. Neoprene is not suitable for use with fuels. Temperature range -50 to 110 deg C

The silicon range of rubbers offer excellent high and low temperature properties, far superior to any other grades. They are also unaffected by sunlight and ozone. They are unsuitable for use against steam and many hydrocarbons. Temperature range -70 to 250 deg C


  • Butyl rubber offers excellent resistance to acidic and alkaline environments.
  • Excellent weathering properties and ozone resistance
  • Low permeability to gases
  • Poor resistance to mineral oils
  • Temperature range - 40 to 130 deg C

Hypalon is noted for its good resistance to corrosive chemicals, ozone and
weathering. It also exhibits good aging, abrasion and heat resistance properties. Hypalon also has low gas permeability. Hypalon offers poor resistance to fuels. Temperature range -50 to 160 deg C

KLINGERLASTIC elastomers are available in a range of thicknesses and sizes. Some elastomer types are available in a range of colours and with reinforcing insertion. Available in sheet, cut gaskets or continuous rolls.
