I want to run a polypropylene drawing factory. How to distinguish injection grade, extrusion grade and drawing grade? What is the difference between them? What's the ingredient?
I am the main supplier of opp recycled particles to polypropylene wire drawing manufacturers. It is very simple to identify the drawing grade by lighting it with a lighter to melt it. If there is no pimple on the wire, it can be used on the computer. You can contact 1 wujiu Wu3522539 if you need help. The drawing effect is very long and short. The wire drawing effect on the wire drawing machine is not very good. This is a direct, intuitive and simple identification method.
