Problems solved by technology

[0006] Most manufacturers at home and abroad have improved their equipment and added a mandatory feeding device during the feeding process to improve the uneven dispersion of antimony trioxide flame retardants due to their high specific gravity. Increased processing cost and processing control difficulty
Especially in terms of high environmental protection and flame retardant performance requirements for smoke suppression, the flammability of plasticizers in polyvinyl chloride and the poor mechanical and mechanical properties of inorganic magnesium-aluminum flame retardants restrict the use of polyvinyl chloride materials in high-end products or Application of wire and cable insulation layer sheath in special environment
The wire and cable industry is an industry with a high degree of industrial correlation, and the demand for flame-retardant materials will maintain a high growth rate in the last ten years, but due to the performance defects of PVC materials, it is not well understood. Improvement, the industrialization development at home and abroad is bound to be restricted in the short term
