Standards to evaluate quality PVC compound materials: Colour, Structure, Surface. Find all the information here about standard PVC Compound.
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 PVC compounds have made part of our modern world.
PVC Compound granules – material properties
The fact that PVC compounds have become so popular in many different applications shows that its natural properties are extremely useful and special. Talking about the hardness: the material in its pure form is very hard but it becomes plastic if mixed with other manufacturing agents. This special feature makes it suitable for the production of products that apply in a wide variety of fields, from construction to automotive.
Furthermore, hazards can arise from the fact that if the compound exists at high temperatures, it will release chlorine molecules such as hydrochloric acid or dioxins. Exposure to this substance can cause health problems.
In order for the polymer to be compatible with industrial production, during the production process, the PVC compound manufacturer instructs the customer to blend the mixture. Additives such as stabilizers, plasticizers, colorants and lubricants. They will help in the manufacturing process as well as make it more flexible, less prone to wear and tear.
Production process at PVC factory
Based on its properties and hazards, the product granules must be produced in specialized 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. Compounds are made by mixing ingredients together. Then, under the influence of temperature, the compound transforms into a gel-like product. 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. In contrast, PVC-U is the designation for compounds without plasticizers for applications.

The criteria for evaluating the quality of PVC compounds
With the diverse applications and properties 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 this products daily need to understand the basic standards of this product to choose a reputable supplier.
3 basic standards to evaluate quality PVC compound materials, including:
Color
Standard PVC particles 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. When these plastic particles become manufacturing materials in applications, they often produce discolored products, which can even be hazardous to health. Businesses should note this feature 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, you need to check and choose sturdy and thick products to ensure durability and safety when using.
Surface
The surface of products is also a factor that makes it easy to distinguish standard product or not. If the 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 contrary, if the production does not meet the above conditions, the finished product will have a rough surface.
