PU foam color, also known as foaming paste, is a high-concentration paste-like colorant obtained by mechanical refining after mixing with an appropriate amount of stabilizer, dispersant and pigment based on polyurethane resin. It has the characteristics of good dispersion performance, low viscosity,......

How to judge the quality of high-density sponge? Next, the PU pigment manufacturer will share it with you. 1. Appearance: Except for the special large-pore and random-porous sponges, the more delicate the appearance of the general sponge, the smaller the pores, the better.

Amine Catalyst A33 is a liquid catalyst containing 33% triethylenediamine (TEDA). This highly active tertiary amine catalyst promotes the reaction of isocyanates with polyols to crosslink the foam. And give flexible polyurethane foam good mechanical properties. If the amine catalyst A1 is used in co......

Anyone who has studied chemistry knows the chemical term catalyst. A catalyst is a chemical substance that is often used in chemical experiments. It can change the chemical reaction rate of the reactants without changing the chemical balance. What is the application of catalyst?

PU red paste is suitable for PU soft foam coloring. It has good dispersibility and good solubility in use, so using the natural color paste can get PU products with uniform color and bright colors.

Usually in the process of sponge production, the foaming speed is too fast, and the pores of the sponge are too large and not delicate enough. In the production process, a reasonable and basic formula plays a key role. The situation discussed in this article is based on the premise that the process ......
