Why Do Polypropylene Masterbatches Add Wax?

Why do polypropylene masterbatches add wax? Adding wax to polypropylene masterbatches can increase the gloss and processing performance of the product. Wax additives are widely used in polypropylene masterbatches. At the same time, they have good compatibility with resins such as polyethylene, polyvinyl chloride, and polyolefins, and have excellent external and internal lubrication.

What kind of wax is used in the processing of polypropylene?

1. When a large amount of fillers are added to polypropylene, injection molding is more difficult, the product surface is rough, and it is not easy to demold. After adding an appropriate amount of polypropylene wax (generally 7~8%), the fluidity of the blended product can be improved, the materials can be dissolved and miscible, the finished product can be easily demolded, and the surface finish of the finished product can be significantly improved.

2. When making polypropylene drawing woven bags with higher viscosity, adding WPP type polypropylene wax can increase its MI value, increase lubricity and fluidity, reduce flat wire breakage, and improve cleanliness. It is an ideal modifier for polyolefin melt index.

TIANSHI polypropylene wax is a new type of chemical product that can replace similar imported products. It has high practical value, improves production efficiency, reduces production costs, and has obvious economic application benefits. The melting point of polypropylene wax is higher than that of polyethylene wax. It has high melt viscosity, good dispersibility, good lubrication effect, strong chemical resistance, excellent electrical properties, and strong moisture resistance at room temperature.
