Plastic sleeve bushings polymer resin bearing plastic washers
This 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 the thermal expansion, moulding shrinking rate and wriggle capability decrease, consequently, the size stablity is improved, and this series material range is enlarged and keeps the intrinsic anti-wear capability and anti-drug capability.
