This datasheet of VESTORAN 1900-GF20 blk (sw) 2.7026 from Evonik Industries AG is provided by the international plastics database CAMPUS.
CAMPUS is organized by a group of leading international resin producers, who have agreed to test their material according to uniform conditions, based on ISO standards (ISO 10350, ISO 11403), in order to offer comparable data to the market.
VESTORAN® is the registered Evonik Degussa GmbH trademark 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® 1900-GF20 blk 2.7026 shows very small mold shrinkage.
Therefore molded parts have a very low tendency to warp.
Moldings of VESTORAN® 1900-GF20 blk 2.7026 are dimensionally stable and hydrolysis resistant even in hot
water, but are more sensitive to organic solvents than semi-crystalline plastics.
VESTORAN® 1900-GF20 blk 2.7026 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® 1900-GF20 blk 2.7026 is particularly suitable for the adhesion promoterfree manufacturing of
plastic /rubber composites by the Evonik Industries AG - patented K&K process.
Compared to VESTORAN® 1900, VESTORAN® 1900-GF20 blk 2.7026 offers higher rigidity and strength.
VESTORAN® 1900-GF20 blk 2.7026 is supplied as ready-to-process cylindrical granules in PP bags.

PREPROCESSING INFORMATION
Maximum Water Content: 0.1 %
If the given water content is exceeded or silver streaks appear on the surface of parts, the resin should be dried.
Drying should be carried out is a dry air or vacuum dryer for at least 3 to 4 hours at 90 - 120°C. The resin should
be pre-heated to 80 - 110°C before molding. If a vented plastizier zone employed preheating can be omitted.
