Soft polyurethane foam rigid PU reaction catalyst A33 for faaming products factory

Product Description

A-33 is a liquid catalyst containing 33% triethylenediamine (TEDA). This highly active tertiary amine catalyst promotes the reaction between isocyanate and polyol and crosslinks the foam. And give flexible polyurethane foam good mechanical properties. If used together with the NIAX catalyst A-1, the best performance of this catalyst A-33 can be obtained.

It is characterized by large catalytic activity, smooth foaming, large tolerance to tin, easy adjustment of formula, and physical and chemical properties such as rebound rate and elongation of products produced with it are superior to other products.

Declaration: The data provided above are typical value, which are tested by our company. For our company's products, the data included in the law do not have any constraints.

Applications

A-33 catalyst is suitable for the manufacture of all kinds of polyurethane foams. It is completely soluble in water and can be completely mixed with polyols, fluorocarbons and stannous catalysts. In all foam formulations, 3X A33 catalyst can replace 1X solid triethylenediamine, Eg. 0.3phpA33 catalyst, can replace 0.1php solid triethylenediamine.

A33 has a wide range of applications in polyurethane flexible foam, polyurethane rigid foam, bulk foam, high rebound foam, high rebound car seat, rigid spray foam, rigid wood imitation foam, polyurethane composites, waterproof coatings, polyurethane adhesives.

Emergency treatment

A33 has certain toxicity. For example, many amine compounds have irritating odors, and are irritating to the skin and eyes. Some heavy metal compounds are relatively toxic. Therefore, personal protection should be used when using them. Wash with soap, rinse with water, and seek medical attention if necessary.
