A33 is a liquid catalyst triethylene diamine (TEDA). This highly active tertiary amine catalyst promotes the reaction between is ocyanate and polyol and cross links the foam. And give flexible and hard pu foam good mechanical properties.
The following is an introduction to Catalyst A33, I hope to help you better understand Catalyst A33. Welcome new and old customers to continue to cooperate with us to create a better future together!
Catalyst A300 is specifically designed for pu automotive seat and backrest. This type pu foame sponge have excellent opening properties and keep the stability of the foaming formula and does not collapse. For systems which use MDI components, fast reaction and slow flow .it can improve foam fluidity.
