Product Texts
Modified polyphenylene ether (PPE), high heat resistant, 20 % glass fiber-reinforced

VESTORAN® X7342 is the registered trademark of the 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® X7342 shows very small mold shrinkage. Therefore molded parts have a very low tendency to warp.

Moldings of VESTORAN® X7342 are dimen­sionally stable and hydrolysis resistant even in hot water, but are more sensitive to organic solvents than semi-crystalline plastics. VESTORAN® X7342 is resistant to aqueous alkalines and acides, certain alcohols, and glycol solutions.

Due to the glass fiber-reinforcement the compound 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 part.
 
VESTORAN® X7342 is supplied as cylindrical granules in polyethylene packaging.
 
Processing advice is given in a separate product information.

Pigmentation may affect values.
