BUTYL RUBBER (IIR)
BUTYL RUBBER (IIR) has very low permeability rate, good electrical properties,resistance to weathering & ozone.
Temperature : -40°C to 120°C
Chemical Resistance : Hot Water, Steam, Ozone, Ageing, & Weather Resistance,Silicon Oil & Grease.
NATURAL RUBBER (NR)
NATURAL RUBBER, the oldest rubber available having outstanding resistance to tear, abrasion and cut growth.
Chemical Resistance : Water Oxidation, Alcohol and Ketones,Moderate Resistance to Acids,Alkalis.
ETHYLENE PROPYLENE RUBBER (EPDM)
EPDM (Ethylene Propylene Diene Monomer) rubber is a co-polymer of ethylene & propylene with ethylene as its main component. The ethylene content is between 45% to 85%, higher the ethylene content, higher is the loading possibility of the polymer resulting in better mixing & extrusion.
Higher crosslink density can be achieved by giving it peroxide curing.
Properties : EPDM is most compatible with substances which are polar, ie cold
& hot water, many hydraulic fluids, alkalis and more, it also has excellent resistance to weather, heat, ozone and steam.
- Architectural Sealing
Compatible : To Hot & Cold Water, Alkalis, Hydraulic Fluids, Ketones, Ozone
Not Compatible : To Oils, Kerosene, Petroleum Based Products, Food
applications that expose rubber to aromatic hydrocarbons.
Temperature : -55°C to 150°C
Chemical Resistance :Hot Water and Steam, Glycol based brake fluids, Organic And Inorganic Acids, Phosphate Ester Based Fluids, Soda, Potassium, Silicon Oil and Grease, Ozone,Aging and Weather resistant.
ASTM CLASSIFICATION: M
