The pu pigment manufacturer is to reveal the soft foam sponge box foaming process: small-scale foam production usually uses the box foaming process, which is an intermittent production process. This foaming method is developed on the basis of manual foaming in the laboratory.

PU color paste, as the name suggests, is a pigment concentrate, which is developed by using different pigments through rigorous processing techniques such as surface treatment and surface coating of the pigments.

The reason why the required paint color paste cannot be called: 1) The content of titanium dioxide is inappropriate (colors with poor hiding power cannot be displayed). 2) Improper choice of paint color paste (some colors cannot be replaced by other color pastes). 3) Color migration.

Most of the flame retardants used in sponges are additive flame retardants, while reactive flame retardants are mainly used in thermosetting resins such as epoxy resin and polyurethane. The original function of flame retardants is to interfere with the three basic elements of oxygen, heat and combus......
