Introduction of Polyurethane Delay Catalyst UV Absorber Manufacturer

Who has a polyurethane delayed catalyst introduction? Delayed catalyst, that is, polyurethane delayed catalyst, is a type of special polyurethane catalyst that has a longer operating time than conventional catalysts and does not affect the post-curing of products. Delayed catalyst itself is also a kind of positive catalyst. Adding it to a catalyst-free system will only speed up the reaction speed of the system and will not inhibit the reaction speed. Delayed catalysts are widely used in polyurethane rigid foam, polyurethane flexible foam, molded foam, polyurethane adhesives, coatings, elastomers, shoe sole slurry and other fields. Generally speaking, delayed catalysts can be divided into delayed foaming catalysts and delayed gelling catalysts, both of which can be widely used in the field of polyurethane foam, while delayed gelling polyurethane catalysts are mostly used in the field of CASE. Thermal sensitive catalyst is also a kind of delayed catalyst. Delayed amine catalyst A-300 is a delayed cross-linking catalyst specially designed for the production of automobile seat cushion and backrest polyurethane. The production of foamed plastics will have more open cells, but at the same time maintain the stability of the foaming formula and will not collapse. For systems containing modified ingredients, fast response and slow flow, the fluidity can be improved. Delayed Amine Catalyst C-225 is an amine catalyst for fast demoulding and high resilience polyurethane foam. This catalyst balances the foam-forming and maturation reactions, optimizes the flow of the reaction mixture, and at the same time reduces the demoulding time. So the delayed amine catalyst C-225 is the best additive for the turntable car seat production line. Delayed amine catalyst A-400 is a water-soluble tertiary amine complex catalyst with delayed catalytic effect for molding polyurethane foam, especially designed for the production of automobile seat cushions. Delayed amine catalyst A-400 can be mixed with water or polyether polyol alone to measure. Good for long pour time and increased open cell foam structure. Delayed amine catalyst A-400 and widely delayed amine catalyst A-300 are both new types of delayed action catalysts.
