Today we bought some recycled polypropylene resin for one of our overseas customer’s plastic pieces production.
In the precess of material selection, thanks to our years of experiences in plastics production, we finally find a good quality PP resin from most of the scraps which can meet our customer’s plastic parts quality requirments well. Here are some good ways of material selection:
1. Transparent resin is always a good quality than the opaque.
2. Choose the glossy resins.
3. Bad materials got coarse and dull in cutting surface.
4. Good materials are always above the water.
5. Burn and smell them, the closer to vrigin the better.
6. Burn and pull the melting part which good quality resin can got even silk in plastic.
7. Burn the materials and you will find bad resins got thick smoke and drip quickly.
8. Chew it and the soft one may mixed with polyethylene.
Hope the above listed ways can help you in plastics materials selection, and we are very glad to sharing them.
