KLINGERLASTIC Elastomers
 
Elastomeric sheet compounds mark the entry level to Klinger's sheet-sealing range of products. Consisting of base polymers with the insertion of vulcanising agents, fillers, pigments and various additives, elastomeric gaskets offer effective, low sealing stress seals typically for low temperature, low pressure applications. Elastomeric gaskets have relatively soft compression characteristics requiring relatively low loads to effect a seal, incorporated with excellent recovery properties due to their self-energising behaviour.
 
NATURAL RUBBER (NR)
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 (NBR)
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 (FPM)
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
 
ETHYLENE PROPYLENE (EPDM)
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
 
STYRENE BUTADIENE (SBR)
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 (CR - POLYCHLOROPRENE)
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
 
SILICON (VQM)
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 (IIR)
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 (CSM - CHLOROSULPHONATED POLYETHYLENE )
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.
