What are PVC compounds used for?

PVC compound has a bright color, corrosion resistance, strength and durability. Due to the addition of some toxic excipients such as plasticizers and anti-aging agents in the manufacturing process, its products usually do not store food and medicines.

Chemical industry: PVC compounds can be used as reactors, pipes, vessels, pumps, valves, etc. are used and are used in chemical production plants to solve corrosion and wear.

What are the properties of PVC compounds?

1. Physical properties of PVC compounds

Polyvinyl chloride resins are thermoplastics with amorphous structure. Under UV light, hard PVC fluoresces light blue or violet-white, while soft PVC fluoresces blue or blue-white. The physical and mechanical properties of polyvinyl chloride depend on the molecular weight of the resin, the content of plasticizers and fillers.

⒉The thermal properties of PVC compounds

The softening point of polyvinyl chloride resin is close to the decomposition temperature. To ensure normal forming and processing, two of the most important process indicators are given for polyvinyl chloride resin, namely decomposition temperature and thermal stability.

3. Stability of the PVC compound

Polyvinyl chloride resin is a relatively unstable polymer and is also degraded under the influence of light and heat. The process is to release hydrogen chloride, and the structure changes, but the degree is relatively low.

What chemical properties do PVC compounds have?

PVC compounds are alkane inert polymers with good chemical stability. It is resistant to corrosion by acids, alkalis and aqueous saline solutions at room temperature, but not resistant to strong oxidants such as oleum, concentrated nitric acid and chromic acid.

Polyethylene is insoluble in common solvents below 60°C, but swells or cracks with prolonged contact with aliphatic hydrocarbons, aromatic hydrocarbons, halogenated hydrocarbons, etc. If the temperature exceeds 60°C, it can be dissolved in a small amount in toluene, amyl acetate, trichloroethylene, turpentine, mineral oil and paraffin; If the temperature is higher than 100℃, it can be dissolved in tetralin.
