Main Applications
DS600:Extrusion processed for generic type resin, mainly used for wire insulation layer,
tubes, film, and so on.
DS601: Heat stress cracking resistant plastics, mainly for wire insulation layer, thin-walled tube.
DS602: The low melting resin and heat stress cracking resistant moulding plastic, used for stress
cracking resistant requiring and low or medium speed of processing, mainly for heat shrinkable
tubes, pumps, valves, piping and lining, wire insulation layer.
Attention
The processing temperature should not exceed 420 °C to prevent toxic gas from releasing.
