PVC Compound – the popular material is plastic industry

Polyvinyl Chloride is the full name of this material or Vinyl for short. PVC is present in most of the items around us. PVC compounds are essentially raw materials used to create end products that are used in daily life.

In addition to the well-known product applications such as wires & cables, shoe soles, household plastics, faucets, and pipes, few people notice that even the 70’s CDs, the plastic seats from the 80’s or the shiny black leather pants of the 90’s also contain different types of PVC compounds. There is nothing wrong with claiming that part of our modern world has been built on PVC compounds.

PVC Compound granules - material properties

The fact that PVC compound is widely used for manufacturing in many different applications shows that its natural properties are extremely useful and special. Talking about the hardness of PVC granules: the material in its pure form is very hard but it becomes plastic if mixed with other manufacturing agents. This distinctive feature makes PVC compounds suitable for manufacturing products that are used in a wide range of fields ranging from construction to automotive.

Furthermore, hazards can stem from the fact that, if PVC compound is overheated, it releases chlorine molecules such as hydrochloric acid or dioxins. Exposure to this substance can cause health problems.

To make the polymer compatible with industrial production, during the production process, the PVC compound manufacturer instructs the customer to mix this material with various stabilizers, plasticizers, colorants and lubricants. They will help in the manufacturing process as well as make PVC compounds more flexible and less prone to wear and tear.

PVC Compound – production process at PVC factory

Based on its properties and hazards, PVC compound granules must be produced in specialized PVC manufacturing plants. These factories make sure to have a production line just for this plastic material.

The convention in recording the additive concentration is based on parts per hundred of the PVC resin. The compound is generated by intimately mixing together the ingredients, which is subsequently converted into the gelled article under the influence of heat. Depending on the type of PVC and additives, the compound prior to gelation can be a free-flowing powder (known as a dry blend) or a liquid in the form of a paste or solution.

PVC compounds can be formulated, using plasticizers, into flexible materials, usually called PVC-P. Compounds without plasticizer for rigid applications are designated PVC-U.

How to distinguish standard PVC Compound

With the diverse applications and properties of PVC compound analyzed above, plus a simpler production process compared to other raw materials and manufacturing industries, PVC compound manufacturers and suppliers gradually expand scale and increase productivity to meet the huge consumption not only in the domestic market but also worldwide.

Businesses around the world are looking for a supplier of PVC compound or individual customers who are using PVC products daily need to understand the basic standards of this product to choose a reputable supplier of standard PVC compound

3 basic standards to evaluate quality PVC compound materials, including:

  • Colour

Standard PVC compound will have bright and shiny colors because the plastic resin manufacturer uses standard and quality color additives.

Poor quality pvc particles will be pale in color, or unevenly distributed, somewhat tanned, greasy. These plastic granules, when used as production materials in applications, will produce products that are often discolored, and may even be hazardous to health.

This feature should be paid special attention to when looking for PVC suppliers.

  • Structure

Items containing substandard PVC compounds have a less robust and thinner structure due to the amount of garbled plastic particles and sloppy processing. Therefore, if you are a user using PVC compound, you need to check and choose sturdy and thick products to ensure durability and safety when using.

  • Surface

In addition to the characteristics of texture and color, the surface of PVC compound products is also a factor that makes it easy to distinguish standard PVC compound or not. If the PVC compound material used is a quality material, mixed in the right proportion and meticulously processed, it will have a glossy, smooth and smooth surface. On the other hand, if the above conditions are not met, the finished product will have a rough surface, and even unmixed raw materials will be visible.
