Silicone Surfactant

Product Name: Silicone Surfactant 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. Typical Physical properties Form Clear liquid Viscosity at 25℃,cSt 350 Color, Gardner 3 Pour Point ℃ 3 Specific Gravity, 25℃ 1.06 Flash Point, Pensky Martens Closed Cup(ASTM D 93), ℃ ＞100
