Plaslok 302 Black Impact Grade Woodflour/Flock Filled Phenolic Molding Compound (discontinued **)
Categories:	Polymer; Thermoset; Filled/Reinforced Thermoset; Phenolic; Phenolic, Novolac, Impact Grade, Filled
Material Notes:	Plaslok Corporation was purchased by Plastics Engineering Company (maker of Plenco brand materials) in March 2000. The Plaslok name is no longer in use. Plaslok 302 is a two-stage, woodflour and flock-filled phenolic molding compound. It has low specific gravity, broad molding latitude and an excellent balance of electrical and physical properties. Its high impact strength makes it particularly well suited for thin wall parts, or where mechanical stress is experienced during assembly. Data provided by Plaslok Corporation.
