TEGOMER® A-Si 2322

TEGOMER® A-Si 2322 by Evonik is an amino-functional polysiloxane-based reactive bulk modifier. It exhibits improved molding flow, tack-free properties by release effect and improved flexibility, even at low temperatures. It can be introduced permanently in polyamides, polyurethanes, polyimides and other suitable polymers. It is pre-distributed in polyols, based on polyether or polyester to react with isocyanates to thermoplastic siloxane elastomers. TEGOMER® A-Si 2322 is soluble in most common organic solvents. The usage level ranges from 3 to 30 wt% based on polymer.
