From the perspective of product classification, the five major resins include: polyethylene PE, polypropylene PP, polyvinyl chloride PVC, polystyrene PS, ABS resin. PE, PP, PVC are the most used resins.
From the upstream point of view, PVC raw materials are mainly calcium carbide and ethylene, from coal and crude oil, PP production process for coal, oil, methanol, PDH, etc., PE is mainly oil, from the perspective of raw material cost, PVC, PP and PE is a certain correlation, among which PE and PP are more closely related.
From the downstream point of view, PVC is mainly downstream pipe, profile, floor, film, etc., the terminal mainly corresponds to real estate; PE downstream film, injection molding, pipe, etc., the terminal corresponds to agriculture, consumption, real estate; The main downstream of PP is plastic knitting, BOPP, pipe, injection molding, fiber, etc., and the terminal corresponds to real estate, home appliances, and consumption. All three terminals are corresponding properties.
