Typical application of silane coupling agent in plastics industry
The typical application of silane coupling agent in plastic industry is to combine organic resin with inorganic filler or fiber to form a composite material. Silane forms a "molecular bridge" to establish a strong, stable, waterproof and chemical resistant chemical bond on two weak bonding surfaces The mechanical strength and electrical properties of the composites are improved, and the expansibility and water vapor penetration are reduced. It can improve the wettability between resin and filler, improve the dispersion of filler and control the rheological properties
Vinyl silane is used as crosslinking agent to graft vinyl silane onto polymer, which is crosslinked by hydrolysis and condensation of grafted silane. Vinylsilane as a bifunctional bond can also be used as an adhesion promoter for a variety of mineral filled polymers.
Silane coupling agent can be used in plastics modification industry:
●Adhesion promoter between polymer and filler
●Crosslinking agent for silane crosslinked polyethylene
●Wetting dispersant and coupling agent of fillers
●Physical and chemical properties improver of plastics
●Processing modifier
