We offer a wide variety of high quality rubber materials, sheets and formed products based on the long-established rubber process technologies of Denka Elastlution and the research and technologies of Denka Co., Ltd.
Polymerized isoprenehas a small amount, 7 to 8%, of non-rubber content.
Because it is a natural product, it varies in quality. However, it makes low-priced products with well-balanced physical properties possible.Its weather resistance may be poorer than synthetic rubber.
●Typical physical properties of sheets
Chloroprene rubber (CR) is a chloroprene polymer It is a type of synthetic rubber that is highly flame-retardant, weather resistant and water resistant.
Ethylene propylene rubber (EPDM) is a terpolymer created by adding an amount of diene as a third component to ethylene (CH2=CH2) and propyleneIts greatest feature is its excellent weather resistance.
Styrene-butadiene rubber (SBR) is a copolymer of styrene (C6H5 -CH=CH2) and butadiene (CH2=CH-CH=CH2). Its properties are similar to natural rubber.
Nitrile rubber (NBR) is a copolymer of butadiene (CH2=CH-CH=CH2) and acrylonitrile (CH2=CH-CN). Its greatest feature is its excellent oil resistance.
Isobutylene-isoprene rubber (IIR) is a copolymer of isobutylene ((CH3)2C=CH2) and a small amount of isoprene (CH2=C(CH3)-CH=CH2). Its characteristics include limited gas penetration, excellent airtightness and very low impact resilience.
Silicone rubber (Q) is a methyl vinyl silicone polymer withbonds. It exhibits excellent heat and cold resistance.
