[Chemical Knowledge]：The difference between PVC paste resin powder and PVC powder

Read： 1019 Time：16months ago Source：Transform the World with Simplicity

PVC paste resin powder and PVC powder are commonly used materials in the plastics industry. Although they are all PVC base materials, there are some obvious differences between them. The characteristics and applications of these two materials will be described in detail below.

from the composition point of view, PVC paste resin powder is composed of PVC resin, plasticizer, stabilizer and additives and other raw materials. PVC powder is a simple combination of PVC resin, fillers and additives. Since PVC paste resin powder contains more raw materials, it is easier to form a uniform viscous substance during the manufacturing process.

from the characteristics, PVC paste resin powder has good fluidity and processability, high bonding strength, soft folding resistance. Although PVC powder is strong in rigidity and strength, its fluidity is poor and its processability is relatively poor.

PVC paste resin powder in the manufacturing process can be adjusted by adjusting the formula to change its viscosity and softness, and PVC powder because of a single ingredient can not achieve this adjustment.

from the application point of view, PVC paste resin powder is widely used in the manufacture of plastic products, hard pipe, floor, cable and artificial leather and other fields. Because of its good processability and adhesion, it can be made into products of various shapes and specifications. PVC powder is mainly used in the manufacture of PVC plates, pipes and other rigid materials, and its application range is relatively narrow.

To sum up, there are certain differences between PVC paste resin powder and PVC powder in composition, characteristics and application. The selection of suitable materials needs to be judged according to specific needs and application scenarios. Both PVC paste resin powder and PVC powder are important materials in the plastics industry, and they play an important role in different fields.
