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.
PTFE exhibits outstanding chemical resistance to the harshest media.
Non flammable, inert, self lubricating are some of its special properties
Temperature : -200°C to 260° C
Other Filled grades of PTFE viz. BRONZE, CARBON, GLASS, MOS2 have better mechanical properties than virgin grades.
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
