Introduction of amine catalyst A33
Amine catalyst A33 is a liquid catalyst containing 33% triethylenediamine (TEDA). This highly reactive tertiary amine catalyst promotes the reaction of isocyanate with polyol to cross-link the foam. It also gives good mechanical properties of flexible polyurethane foam. If used with amine catalyst A1, the best performance of this amine catalyst A33 can be obtained. Physical properties: Shape: colorless or light yellow liquid purity ≥99%; water content ≤0.5%; viscosity (25℃): 100mPa.s; density (20℃): 1.033g/cm3; flash point (PMCC): 79℃; vapor pressure (38℃): 266Pa Amine catalyst A33 product application: The active ingredient of Chong Yao A33 is triethylenediamine, which is composed of 33% triethylenediamine and 67% polyol. It is a solution of 33% triethylenediamine and 67% mono-dipropylene glycol. It is widely used in soft, semi-rigid and rigid polyurethane foam, coatings and elastomers. In the polyurethane foaming system, isocyanate first reacts with triethylenediamine to form an active complex, which is very unstable in nature, and once the carbamate bond is generated, it will be freed to facilitate further catalysis. The catalytic effect of triethylenediamine is strong for both gel reaction and foaming reaction, especially for polyurethane and hydroxyl group, which is more selective. Amine catalyst A33 is suitable for all types of polyurethane foam manufacturing. It is fully soluble in water and fully miscible with polyols, fluorocarbons and stannous catalysts. In all foam formulations, triple amine catalyst A33 can replace twice as much solid triethylenediamine, e.g. 0.3php amine catalyst A33 can replace 0.1php solid triethylenediamine. Amine catalyst A33 is widely used in polyurethane soft foam, polyurethane hard foam, sponge big foam, high resilience sponge, car seat high resilience, sprayed hard foam, imitation wood hard foam, polyurethane composites, waterproof coatings, polyurethane adhesives. Amine catalyst A33 Amine catalyst A33 is a liquid catalyst containing 33% triethylenediamine (TEDA). This highly active tertiary amine catalyst promotes the reaction of isocyanates with polyols, resulting in foam cross-linking. The flexible polyurethane foam has good mechanical properties. The optimum performance of the amine catalyst A33 can be obtained if the amine catalyst A1 is used in conjunction with the amine catalyst A1. Physical properties: Shape: colorless or pale yellow liquid A purity of 99% or more. Moisture 0.5% or less; Viscosity (25℃) : 100mPa. S; Density (20℃) : 1.033g/cm3; Flash point (PMCC) : 79℃; Vapor pressure (38℃) : 266Pa Application of amine catalyst A33: Amine catalyst A33 is suitable for all types of polyurethane foams. It is completely soluble in water and can be thoroughly mixed with polyols, fluorocarbons and stannous catalysts. In all foam formulations, triethylamine catalyst A33 replaces one time solid triethylenediamine, for example, 0.3 php-amine Catalyst A33 replaces 0.1 PHP solid triethylenediamine. Amine catalyst A33 is widely used in polyurethane soft foam, polyur ZR-70: Low odor catalyst for packaging foam and molded foam on vinyl skins with good foam and gel balance ZR-40 (pentamethylenedipropylenediamine): Particularly effective for cold molded high resilience foams, good catalyst for low odor gel and foam balance LE-310: Low odor reactive gel catalyst for bulk sponge applications, new low VOC amine gel catalyst LE-530: Reactive gel catalyst for a wide range of polyurethane foams DPA: Low odor gel catalyst with outstanding balance and versatility providing good flowability TAP 1-methyl-4-(2-dimethylaminoethyl)piperazine: Excellent trimer catalyst for improved flowability DMDEE (2,2′-dimorpholinediethyl ether) DMAEE: Strong foaming catalyst, providing stable prepolymer systems DMAEE: Low density all-water rigid foam and low density semi-rigid foam BDMAEE bis-(2-dimethylaminoethyl) ether: Highly efficient foaming catalyst BDMA (N,N-dimethylbenzylamine): Polyurethane rigid foam catalyst, epoxy promoter DMEA (N,N’-dimethylethanolamine): Acid neutralizer in some rigid foam systems, PMDETA (Pentamethyldiethylenetriamine): particularly effective in HCFC/water-blown hard foam, similar to PC5
