DS702: mainly for pumps, valves, piping and lining, mebrane, joint and some bearing.
DS701: mainly used for wire insulation layer, tubes, film, and so on.
DS700: Extrusion processed for generic type resin, mainly used for wire insulation layer, Multi-core cable sheath and so on.
DS708: Mainly for aviation, aerospace and chemical industry, high-speed extrusion wire and cable, It is more economical when used in where no high stress cracking resistance is required.
