>High-performance foaming masterbatch should have high gas generation, good dispersion and nucleation ability and good compatibility with the application resin. Its components are mainly composed of foaming agent, nucleating agent, dispersant, carrier resin and other additives. constitute.

Foaming agent Sodium bicarbonate is an inorganic foaming agent, characterized by large gas generation, non-toxic, cheap and wide in source. It is an endothermic reaction during decomposition. It has poor dispersion in polymers and good storage properties. The decomposition process is gentle. The decomposition temperature is ~°C. The gas released after decomposition is , which is non-toxic and tasteless.


Selection of carrier resin

①The carrier resin must have good fluidity and match the matrix resin

②The carrier resin must have certain Mechanical properties, and has a good coating effect on the nucleating agent, foaming agent and lubricant

③The carrier resin should be similar in structure to the matrix resin and have good compatibility with the matrix resin. .

We choose resin as the carrier resin for preparing foaming masterbatch. It is a random copolymer of ethylene and vinyl acetate. Many of its properties are closely related to the content of vinyl acetate. When the content increases, its polarity becomes stronger, and its elasticity, softness, adhesiveness, transparency, and solubility increase. When the content decreases, it approaches the properties of polyethylene, becomes more rigid, and has increased wear resistance and electrical insulation. It can be seen from this that it has a wide resin adaptability, and the processing temperature is low, making it easy to prepare masterbatch.
