Item No.: Silibase-2890B
Equivalent Product: NIAX* Silicone L-5107 LF
Silibase-2890B is an organosilicone copolymer which is an excellent candidate to consider for resin side addition in the manufacture of rigid polyurethane foams, delivering a lower freezing point.
Key Features and Typical Benefits
Silibase-2890B is foam stabilizer surfactant can enhance foam mechanical properties and compressive strength in foams obtained by Spray, Lamination and Block process.
Silibase-2890B can be used in formulations based or containing polyester polyols.
Silibase-2890B yields foam with very good cell isotropy and allows good flow ability and physical properties.
Silibase-2890B is suitable for all blowing agents, delivering regular cell texture and improving components compatibility. Normal usage level is at 2% in the resin side or 0.8% in the total A+B side formulation.
