PP is divided into film grade, injection grade, extrusion grade,
yarn grade, pipe grade, raffia grade etc.
PE-LDPE, LLDPE, HDPE, MDPE
LDPE-low density polyethylene, we can provide film grade, injection
grade, blowing grade, extrusion grade, coating grade, etc.
LLDPE- linear low density polyethylene, we can provide film grade,
injection grade, extrusion grade, blowing grade, etc.
HDPE-High density polyethylene, we can provide injection grade,
pipe grade, film grade, exxtrusion grade, blowing grade, wire and
cable grade, etc.
Regard to PP and PE(including LDPE, LLDPE, and HDPE)we can provide
both virgin and recycled/reprocessing grade.
Besides, our company also provide GPPS, HIPS, ABS, PVC, PET, etc.
Usually, PP injection moulding grade is used for auto parts,
corrugated board, equipment tools, toys, containers, battery box,
For the below technical PP injection grade, Sinopec brand with
these features: Good hardness and impact strength, long-term
thermal stability, low temperature impact strength, easy to shape.
