HDPE grafted maleic anhydride (W1H)

Model No.: W1H

lntroduction:

W1H can improve the interface affinity between polyolefin substrate and inorganic substances such as metal powder, glass fiber, wood powder, mineral powder, starch, etc., so as to achieve the effect of enhancing the strength of composite materials

W1H is a method of grafting maleic anhydride groups on the molecular chain of high-density polyethylene through chemical reaction, so that the end of high-density polyethylene has the reactivity and strong polarity of maleic anhydride polar molecules.

W1H is a type of chemical compound that is used to graft maleic anhydride (MA) onto the molecular chain of high-density polyethylene (HDPE) through a chemical reaction. The process of grafting involves attaching MA groups to the HDPE chain, which can then react with other polar molecules or surfaces, resulting in improved adhesion and compatibility with other materials.

This process is often used in the production of various polymer composites, coatings, and adhesives, where the polar MA groups on the HDPE backbone can improve the bonding properties of the material. Additionally, the presence of MA groups can also provide other functional benefits such as improved thermal stability, flame retardancy, and resistance to UV radiation.

Description

W1H grafts maleic anhydride groups on the molecular chain of high-density polyethylene through chemical reaction, so that the end of high-density polyethylene has the reactivity and strong polarity of maleic anhydride polar molecules.

Characterisitic

W1H is often used as a compatibilizer for polyolefin materials. This product can also be used as a surface improver for extruded sheets or extruded sheets, which can effectively improve the surface flatness of sheets or sheets, and eliminate surface unevenness and pitting of materials.
