What is the role of polyethylene wax in hot melt adhesives

2021-06-09   Pageview:592

Polyethylene wax has good compatibility with polyethylene, polypropylene, polyvinyl waxate, ethylene propylene rubber and butyl rubber. It can change the fluidity of polyethylene, polypropylene, ABS and the demoulding property of polymethyl methacrylate and polycarbonate.

The performance of PE wax in hot melt adhesive:
1, Enhance the infiltration and adhesion performance
2, Improve strength
3, Improve the performance after maturation
4, Adjustment of opening time and curing time
5, High compatibility (polarity adjustment)
6, Surface performance (glossy, smooth, no precipitation)
7, Better thermal stability (does not affect the resin color, no yellowing)
8, High molecular weight polymer (low volatility, no migration)

Polyethylene wax has good stability when applied in hot melt adhesive, and the thermal stability is better. It does not precipitate at high temperature and has no effect on the appearance of hot melt adhesives. The hot melt adhesive produced by adding polyethylene wax has good cold resistance, heat resistance, acid and alkali salt corrosion resistance and thermal stability, anti-slip, good fixation, high adhesive strength, excellent temperature resistance, etc.
