| Modified polyphenylene ether (PPE), high heat resistant, 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 (poly-phenylene ether, PPE, also referred to as PPO). As a material of amorphous structure VESTORAN 1900 shows very small mold shrinkage. Therefore molded parts have a very low tendency to warp. The impact modified compound is of low density and easy to process. Further properties are excellent impact strength, heat deflection under load and suitability for being coated with lacquers. Moldings of VESTORAN 1900 are dimensionally stable and hydrolysis resistant even in hot water, but are more sensitive to organic solvents than semi-crystalline plastics. VESTORAN 1900 is resistant to aqueous alkalines and acides, certain alcohols, and glycol solutions. Colored material contains only cadmiumfree pigments. VESTORAN 1900 is particularly suitable for the adhesion promoter-free manufacturing of plastic/ rubber composites by the Evonik Degussa GmbH-patented K&K process.&& |
