PVC paste resin is a paste-like PVC resin with fine particle size and immobility. texture like talcum powder. PVC paste resin is different from PVC resin in terms of production process and application.
PVC resin
At a certain temperature, under the action of initiator, dispersant and water, the vinyl chloride monomer can obtain a white suspension with a homozygous reaction. Then the suspension is centrifuged and filtered and air-dried to obtain a white powder.
It can mixed with a variety of additives and processed by thermal plasticization to obtain PVC plastic products such as hard boards, pipes, doors and windows.
The main differences of PVC paste resin and PVC resin:
In particle size: the particle size of PVC paste resin is 30-60 microns (um), while PVC resin is 50-250um;
Output: more than 80% of ordinary resin (suspension resin), about 10% of paste resin; and 10% of special PVC resin;
Processing: PVC suspended resin is thermally plasticized first and then molded, which can be made into soft and hard products, and the processing equipment is complicated.
PVC paste resin is formed first and then thermoplasticized, and can only be made into soft products, the processing equipment is also simple and inexpensive.
