Coupling agents and compatibilizers are essential additives used in the plastics industry to improve the compatibility, bonding, and overall performance of different materials. These agents help to enhance the adhesion between various polymers, fillers, or reinforcements, improving the quality and mechanical properties of plastic products. They are widely used in producing high-performance composite materials, foams, and coatings.
Coupling Agent | Key Properties | Applications |
---|---|---|
Maleic Anhydride Grafted Polypropylene (PP-g-MAH) | Improves adhesion between polypropylene and other materials | Automotive parts, packaging materials, composite materials |
EVA-g-MAH (Ethylene Vinyl Acetate Grafted Maleic Anhydride) | Enhances compatibility between ethylene-based polymers and other materials | Films, wires, cables, flexible products |
KH-550 (γ-Aminopropyltriethoxysilane) | Improves bonding between organic polymers and inorganic materials | Composite materials, coatings, adhesives |
KH-560 (γ-Glycidoxypropyltrimethoxysilane) | Improves bonding and adhesion in fiberglass-reinforced plastics | Automotive, construction, coatings, adhesives |
A-187 (γ-Glycidoxypropyltrimethoxysilane) | Improves bonding and adhesion in composites and coatings | Composite materials, coatings, adhesives |
Coupling agents and compatibilizers are used in a variety of applications across industries. Some of their key uses include:
