What Are The Types Of PVC Resin Powder

PVC resin powder is suitable for processing equipment of various common polyvinyl chloride resins, and can be calendered, extruded and injected into various products. Matting occurs on the surface of the product, and it has good characteristics in terms of vision and hand. According to the specific requirements of different products, users can add an appropriate amount of matting resin on the basis of their original product formula to produce matting products that meet the requirements.

The raw materials for the production of PVC (polyvinyl chloride powder) resin are: vinyl chloride monomer in peroxide, azo compound and other initiators; or under the effect of light and heat according to the mechanism of self-based polymerization. of polymers.

PVC is a white powder with amorphous structure, the degree of branching is small, the relative density is about 1.4, the glass transition temperature is 77~90 °C, and the differentiation starts at about 170 °C, and the stability to light and heat is poor. Above 100 °C or after a long time When exposed to sunlight, it will decompose and generate hydrogen chloride, which will further actively catalyze the decomposition, causing discoloration, and the physical and mechanical properties will also decrease rapidly. In practical use, it is necessary to add stabilizers to improve the stability to heat and light.

PVC was once the most widely used general-purpose plastic in the world. It is widely used in building materials, industrial products, daily necessities, floor leather, floor tiles, artificial leather, pipes, wires and cables, packaging films, bottles, foam materials, sealing materials, fibers, etc.

1. Product description: PVC resin powder, called polyvinyl chloride, is a non-toxic and odorless white powder with high chemical stability, good plasticity, and excellent electrical insulation. It will burn, it is a "self-extinguishing", "flammable" substance, it is the first in my country and the second largest general-purpose synthetic resin material in the world...

2. Product use: PVC resin powder is widely used in the production of profiles, profiles, pipes and fittings, plates, sheets, wire and cable sheaths, hard or soft pipes, blood transfusion devices and films, etc. , electricity, medical devices, daily life, packaging and other fields are widely used.
