詳細

アプリケーション

Toughening additive for epoxy polymers.
Additive to urethane foam, cast wheels, coatings, linings and adhesives, at 10-40 wt. %

特徴および利点

Material is hygroscopic. Inert filler and impact-resistant material. Polar surface groups assist chemical and physical bonding to matrix material. Added to urethanes, polysulfides, nitrile rubber and other polymers to lower cost, improve adhesion and increase impact resistance. Low moisture content allows addition to moisture sensitive materials.

物理的形状

Particle surface is oxidized to contain acid groups.
