SI8972

Product Introduction

SI8972 is a silicon-carbon bond non-hydrolyzable silicone surfactant, which is widely used in the production of polyurethane foam building boards, especially for the production of multi-component polyurethane continuous boards. The silicone surfactant has strong nucleation performance and good fluidity of the foam system, which can significantly improve the surface quality of polyurethane board and the stability of foam products.

Product Characteristics

DMCHA

MRCAT DMCHA is as a catalyst for rigid polyurethane foam. It is a low viscosity medium amine catalyst for refrigerator rigid foam, plate, spraying, and on-site infusion of polyurethane rigid foam. The catalyst has a catalytic effect on both gel and foaming, and provides a more balanced catalytic performance for the foaming reaction and gel reaction of rigid foam. It has a stronger catalytic effect on the reaction of water and isocyanate (foaming reaction), and also has a moderate catalytic effec

PMDETA

MRCAT PMDETA is a highly active strong foaming polyurethane catalyst, which is also used to balance the overall foaming and gel reactions. It is widely used in all kinds of polyurethane rigid foam, including polyisocyanurate sheet rigid foam, can improve the foam fluidity, so it can improve the production process and improve the quality of products. MRCAT PMDETA can be used alone as a catalyst for polyurethane foam formulations or with other catalysts such as MRCAT DMCHA. When used alone as the
