General information on rubber and jointing materials

Rubber/Rubber insertion.

A general gasket material with high resilience, and depending on the grade, good abrasion resistance. Has fair resistance to many organic chemicals. Reasonable weather resistance, but avoid ozone and direct sunlight. Avoid oils, oxidising agents, e.g. Nitric and Chromic acids, Aromatics and Hydrocarbons. Insertion is available to British standard specs. Temp range -40C to 70C.

Ethylene Propylene Rubber (EPDM)

All EPDM Rubber stocked is Water Research Council Approved. Since the majority of our EPDM Rubber is used in the potable water industry, we are acutely aware of the need to maintain a standard of material on which our customers can have complete confidence. It has high and low temperature stability as well as steam and water resistance. It has good resistance to glycol-ether hydraulic fluids but is not suitable for contact with petroleum fluids. Temp range 40C – 120C

Neoprene

Has a good resistance to weathering, ozone, sea water and a wide range of chemicals. Neoprene has a good resistance to heat and does not soften as natural rubber under severe exposure. Fair resistance to many oils, but not suitable for use with petrol. Temp range -20C to 100C

Nitrile

Very good resistance to oils, grease, liquid fuels, and other petroleum products. Nitrile has a good heat and abrasion resistance. It is not recommended for ozone, sunlight or weather resistance. Temp range -20C to 110C

Butyl

Excellent for Ozone, weathering, and chemical attack. It has a very low gas and moisture permeability and has good electrical insulation properties. Butyl is not suitable for use with petroleum oils, fluids and aromatic hydrocarbons. Temp range -50C to 120C

Food Rubber

Used in Food Industry it is a white tasteless rubber for non-fat foodstuffs. Temp range -40C to 70C

Shortblast Rubber

Excellent wear and as required in shortblasting applications it has ompact and abrasion resisting properties. Shortblast rubber comes in different qualities and has shore hardness range from 30/40 to 55/65

Silicone Rubber

Excellent heat resistance and weather resistance, and for low and high temperatures. Good chemical resistance, but poor abrasion and steam resistance. Silicone does not have high tensile properties. Tem range -60C to 200C

Closed Cell Neoprene

Plain or self adhesive, it is supplied in strip, sheet and gasket shape form. It is weather, heat and oil resistant, meeting ASTM D 1056. Constant Temp 85C or intermittent up to 100C

Oil Cell Sponge

Structured to permit liquid food absorption. Good compression and recovery properties.
