Coupling Agent for PA

Westrchem ® STR-150 is a High cost performance type coupling agent for PA, It is a method of chemical reaction to connect maleic anhydride molecules onto the molecular chain of linear low-density polyethylene, so that the polyethylene end has the reactivity and strong polarity of maleic anhydride polar molecules. Therefore, it can improve the interfacial affinity between polyolefin substrates and inorganic materials such as metal powder, glass fiber, wood powder, mineral powder, starch, etc., thereby enhancing the strength of composite materials. It is often used as a compatibilizer for polyolefin materials. When this product is used in low smoke and halogen-free flame retardant cable materials, it can improve the compatibility and adhesion between the polyolefin matrix and the inorganic flame retardant interface. Improve the dispersibility and compatibility of magnesium hydroxide and aluminum hydroxide, thereby maximizing the flame retardancy of cable materials, reducing smoke index, smoke generation, heat generation, and carbon monoxide production, increasing oxygen index, improving dripping performance, and improving the mechanical properties of materials. This coupling agent for PA can also be used as a surface improver for extruded sheets or extruded sheets, effectively improving the surface smoothness of the sheets or sheets, and eliminating surface bumps and pits.
