The role of PVC lubricant in the film? In the formula of soft products, too much pvc lubricant will frost and affect the strength, high-frequency welding and printability of the products. If the lubricant is too little, the roller will stick. For the blown film, if the lubricant is too little, the die will stick and the plastic will coke in the die.
In hard PVC plastics, excessive lubricant will reduce the strength and affect the process operation. For injection products, peeling will occur, especially near the gate.
The chemical properties of oxidized polyethylene wax are very excellent. It has good compatibility with fillers, pigments and polar resins, and is superior to polyethylene wax in lubricity and dispersion. It is an upgraded version of polyethylene wax
What is oxidized polyethylene wax? Oxidized polyethylene wax, also known as OPE wax, has low viscosity, high softening point, good hardness and other special properties, non-toxic, good thermal stability, low high temperature volatility, and has excellent external lubrication and strong internal lubrication for the dispersion of fillers and pigments.
As a PVC lubricant, what is the role of oxidized polyethylene wax in the film?
1. Excellent performance, improve production efficiency and reduce production costs. It can improve the production efficiency of plastic processing and reduce the production cost. Because there is a certain hydroxyl group on the molecular chain of oxidized polyethylene wax, their solubility with polar resin is significantly improved, which is superior to polyethylene wax.
2. Lubricity, improve the surface finish of products, and effectively improve the quality of products. The internal and external lubrication of PVC is relatively balanced.
3. Widely used, one product can be used for many purposes. It is widely used in PE, PVC cable materials, PVC profiles, PVC pipes, and is an excellent new plastic lubricant. It can also be used as raw and auxiliary materials for making textile soft type, car wax and leather softener.
Plastic products are actually a mixture of plastic resin and various pigments, fillers and additives. The dispersion of pigments, fillers and additives in the resin is crucial to the performance of plastic products. Dispersant is a kind of auxiliary agent to promote the uniform dispersion of various auxiliary materials in the resin. It is mainly used in color masterbatch, colored products and high filling products.
