JS-P80 series material is a thermal mould character plastic processed by crystal engineering plastic as basic material with proper intensifier and lubricant. The rigidity and high temperature engineer capability is greatly improved because of the use of intensifier, at the same time. The coefficient of thermal expansion. moulding shrinking rate and wriggle capability decreases consequently, the size stability is improved. And JS-P80 series material range is enlarged and keeps the intrinsic anti. Wear capability and anti-drug capability.
