What are the physical and chemical properties of PVC compounds?

The natural color of the PVC compound is yellowish translucent and shiny. The transparency is better than that of polyethylene and polypropylene, but worse than that of polystyrene. Depending on the dosage of the additives, it can be divided into soft and hard PVC. Soft products are soft and tough and feel sticky. Hard products have a higher hardness than low density polyethylene. Below polypropylene, a white coloring occurs at the turning point.

What are the classifications of PVC compounds?

As a popular chemical material on the market, PVC plastic granulate has been researched by many manufacturers. After years of production research, PVC plastic particles can already appear on the market in different shapes, which can meet the different needs of more users. Today, our manufacturer of PVC plastic granules will introduce you to the various forms of PVC plastic granules.

In the form of PVC tape particles, it is a kind of plastic particle with a soft texture. Due to its soft properties, it is often processed into transparent ribbons. In addition, adding some additives to itself can increase its hardness.

PVC injection molding particle, this kind can be roughly divided into gray, yellow and red, it has very good corrosion resistance, weather resistance and stability, is non-flammable and is very durable when processed into various products, so it is currently one of the most popular products on the market.

PVC environmental protection particles belonging to the special class environmental protection material have no peculiar smell, have strong flowability and are easy to process. They are generally used for making toys, transparent mats, daily necessities, hardware, tool handles, etc. used.

What are the practical applications of PVC compounds?

Due to PVC compound's fire and heat resistance, polyvinyl chloride is widely used in a variety of products in various industries: cable sheathing, fiberglass sheathing, shoes, handbags, bags, accessories, signs and billboards, building decoration products, furniture, ornaments, rolls, hoses, toys, curtains, rolling doors, medical supplies, gloves, Plastic wrap for certain foods, certain fashion items, etc.

What are the physical and chemical properties of PVC compounds?

The light and heat resistance of the PVC compound is low. The softening point is 80°C, decomposition begins at 130°C. Without heating the stabilizer, polyvinyl chloride begins to decompose at 100°C and decomposes faster than 130°C. It is decomposed by heat and releases hydrogen chloride gas (hydrogen chloride gas is a toxic gas), changing its color from white → light yellow → red → brown → black. Ultraviolet rays and oxygen in sunlight cause photooxidative decomposition of polyvinyl chloride, which reduces the flexibility of polyvinyl chloride and eventually becomes brittle. For this reason, some PVC plastics become yellow and brittle over time.

PVC compound has stable physical and chemical properties, is insoluble in water, alcohol, gasoline, and has low gas and water vapor leakage; at room temperature, it tolerates any concentration of hydrochloric acid, sulfuric acid below 90%, nitric acid 50-60% and 20% The following caustic soda has a certain resistance to chemical corrosion; It is quite stable to salts, but can be dissolved in organic solvents such as ethers, ketones, chlorinated aliphatic hydrocarbons and aromatic hydrocarbons.

Like the ZANBOND Group, it has focused on the technical transformation of PVC and the industrial field of manufacturing, setting up a whole range of standardization systems for the development of granulate formulations, laboratory material testing, mold development, machine equipment innovation. Products are widely used in environmental, construction, transportation, daily needs and other fields.

With 16 years exporting experience, our company is a professional manufacturer and exporter concerned with the design, development and production of PVC raw materials & PVC Compound.
