Applications of "DENKA CHLOROPRENE"
(1) Wire and Cable
It is used as the sheaths for wires and cables.
(2) Automotive Rubber Parts
Air suspensions, constant velocity joint boots, rack and pinion boots, power steering hoses, brake hoses, belts for various drives, packing, joints, dust-proof caps, anti-vibration materials are used in the requirements of automobiles.
(3) Belts and Hoses
It has a wide range of applications including conveyor belts, transmission belts, and other flat and V-belts used in mining and other fields. It is also used for various hose covers and tubes.
(4) Rubber Linings, Sponges and Wet Suits
It is used as rubber linings such as container bags, coated cloth for seats and tent curtains, leisure boats, lifeboats, and flame-retardant firefighter protective clothing. It is also used as a foam rubber or sponge with a large foam magnification for wet suits used in marine sports, as well as cushion rubbers and other items that protect human lives from the danger of flames on vehicles such as aircraft and ships.
(5) General Purposes
It is used in rubber rolls of offset printing presses which print with water and oil, rolls for steelmaking that are exposed to oil or high heat, pads and packings for various machines, and gaskets and dust-proof caps. In recent years, in addition to conventional automotive parts and general industrial rubber products, it is also expected to expand applications in civil engineering and construction fields, such as water-stop rubber and bridge rubber bearings, as well as in marine-related rubber parts.
Among a wide variety of rubber-based adhesives, "DENKA CHLOROPRENE" based adhesives have a solid position in various fields of the easy workability and rapid bonding strength. Recently, "DENKA CHLOROPRENE LATEX" has also been well received by many clients for solvent-free adhesives.
