| Modified polyphenylene ether (PPE), heat resistant, glass fiber-reinforced, suitable for plastic/rubber composites manufactured by the K&K process VESTORAN is the registered trademark of Evonik Degussa GmbH for molding compounds containing poly-2,6-dimethyl-1,4-phenylene ether as polymeric constituent (polyphenylene ether, PPE, also referred to as PPO). As a material of amorphous structure VESTORAN 1900GF20 shows very small mold, shrinkage. Therefore molded parts have a very low tendency to warp. Moldings of VESTORAN 1900GF20 are dimensionally stable and hydrolysis resistant even in hot water, but are more sensitive to organic solvents than semi-crystalline plastics. VESTORAN 1900GF20 is resistant to aqueous alkalines and acides, certain alcohols, and glycol solutions. Glass fiber reinforcement of this molding material combines outstanding heat deflection temperature under load with high strength and rigidity. The even smaller shrinkage compared to non-reinforced VESTORAN depends on the orientation of the glass fibers in the molded parts. VESTORAN 1900GF20 is particularly suitable for the adhesion promoter-free manufacturing of plastic/rubber composites by the Evonik Degussa GmbH-patented K&K process. Compared to VESTORAN 1900, VESTORAN 1900GF20 offers higher rigidity and strength. Colored material contains only cadmiumfree pigments.&& |
