What is pvc profile? What are the characteristics?

With the continuous development of the social economy and the continuous improvement of science and technology, we have a lot of decoration materials that we have never heard of when we are doing home decoration. After all, not professionals will understand less, and PVC profiles do not know Have you heard of it? The use of pvc profiles is very extensive, and it can be seen in furniture, indoor and outdoor decoration, and chemical industries. So let's take a look at what pvc profiles are and what are their characteristics.

1. What is pvc profile?

PVC profile is an industrial and daily PVC product formed by adding various functional additives to PVC resin and then extruding at high temperature. According to the performance, it can be divided into two types: hard and soft. Rigid PVC profiles are generally used in construction, such as making PVC doors and windows, PVC floors and PVC pipes; soft PVC profiles can be used for PVC hoses and power cables. The formulation of PVC plastic profiles is actually mainly composed of PVC resin and additives. The additives can be divided into heat stabilizers, lubricants, agents, processing modifiers, impact modifiers, fillers, and anti-oxidants according to their functions. Aging agents and colorants, etc.

Second, what are the characteristics of pvc profiles?

1. Rigid PVC profiles are one of the most widely used plastic materials. PVC profile is an amorphous material.

2. Stabilizers, lubricants, auxiliary processing agents, pigments, impact agents and other additives are often added to PVC-type materials in actual use.

3. PVC material has non-flammability, high strength, weather resistance and excellent geometric stability.

4. PVC profiles have strong resistance to oxidizing agents, reducing agents and strong acids. However, it can also be corroded by concentrated oxidizing acids such as concentrated sulfuric acid and concentrated nitric acid, and is also not suitable for contact with aromatic hydrocarbons and chlorinated hydrocarbons.

5. The melting temperature of PVC profiles is a very important process parameter during processing. If this parameter is not appropriate, it will cause problems with material decomposition.

6. The flow characteristics of PVC profiles will be quite poor, and the scope of its process will be very narrow. In particular, PVC materials with large molecular weights are more difficult to process, so some PVC materials with small molecular weights are usually used.

7. The shrinkage rate of PVC profiles will be quite low, generally 0.2~0.6%.

About what PVC profiles are and what their characteristics are The characteristics are also quite powerful, which must be the reason why it has such a wide range of applications.
