Silane coupling agent CFS-534 can be used as an adhesion promoter for a variety of mineral-filled polymers to improve the physical properties of the filler and protect the interface from moisture erosion. Widely used in ethylene, propylene, diene EPDM rubber and glue-linked polyethylene wire and cable industries.

Silane coupling agent CFS-534 is a bifunctional molecule, which can react with inorganic fillers and organic polymers. Can be used as an adhesion promoter for a variety of minerals: aluminum hydroxide, magnesium hydroxide, kaolin, silica and other filled polymers to improve their mechanical and electrical properties, especially after exposure to moisture. Once this product is combined with inorganic fillers, it will make the surface of the filler hydrophobic, this effect can improve the compatibility of fillers and polymers, so as to reduce the dispersion, melt viscosity, and easier processing of filled plastics.

This product is used to modify ultra-fine powders such as aluminum hydroxide, magnesium hydroxide, kaolin, silica, etc., so that the ultra-fine powder with large surface area, surface energy and surface activity has a strong adsorption tendency to achieve good modification effect. It fundamentally solves the problem of ultrafine particle agglomeration and insufficient modification and uneven dispersion. Active halogen-free flame retardants made of modified aluminum hydroxide and magnesium hydroxide are widely used in (ships, aircraft, mines, subways, power stations, conveyor belts, etc.) wire and cable, electrical switches, engineering plastics, decorative materials, Flame retardant coatings and fabrics.

In the manufacture of wires and cables, this product is commonly used to treat the fillers of cross-linked polyethylene composites to improve the physical properties of the fillers and protect the interface from moisture erosion. The filler fraction can be increased and the tensile strength can be increased by a factor of 1 and the dielectric constant by a factor of 10.

This product is also used in the formulation of high-voltage cables of ethylene-propylene copolymer and ethylene-propylene diene terpolymer to treat talc, quartz and fillers. It can improve the electrical and mechanical properties of the cable insulation layer. It has the advantages of shortening the mixing time, fast extrusion, and improved mold wear. In view of the advantages of low comprehensive cost and good process performance, this product has been adopted by the industry standard specification of ethylene propylene copolymer, ethylene, propylene diene EPDM rubber and cross-linked polyethylene wire and cable.

Adding this product to cross-linked polyethylene and modified polypropylene can improve the adhesion of these polymers to the surface of inorganic fillers.

Silane coupling agent CFS-534 can also be copolymerized with various monomers to make adhesives and sealing coatings with good moisture and heat resistance.
