Read： 1030 Time：9months ago Source：Transform the World with Simplicity

PVC paste resin and PVC resin are common materials in the plastics industry, and their main components are polyvinyl chloride (PVC). However, although they have common components, there are some differences in properties, uses, etc.

PVC paste resin is a semi-solid resin with viscous characteristics. It usually appears as a Milky White or yellow semi-solid material, which can become a mobile material after being gelatinized by heating. PVC resin is a solid or plastic material, can not be gelatinized. This means that PVC paste resin has better fluidity during processing and is easier to be processed by spinning, spraying and other processes. The solid-state nature of PVC resins makes them more commonly used in processes such as molding and calendering.

in use, PVC paste resin is more used in coatings, inks, screen printing and other fields. Its viscous characteristics enable it to bond well with other materials, providing good coating and adhesion. PVC resin is more commonly used in the production of plastic products, such as pipes, cables, flooring and so on. Due to its solid nature, PVC resin has good mechanical properties and weather resistance, and is suitable for various complex engineering environments.

PVC paste resin and PVC resin also have some differences in cost. Generally speaking, the production cost of PVC paste resin is low and it is suitable for mass production. The production cost of PVC resin is relatively high, because the production process requires more processing and molding steps. Therefore, when a large number of plastic products are needed, PVC paste resin is more competitive, and for some products with higher quality requirements, PVC resin is more often selected.

In summary, there are some differences between PVC paste resin and PVC resin in terms of properties, uses and costs. Understanding these differences helps us to choose suitable materials for practical applications to meet different needs. Of course, with the continuous advancement and innovation of technology, the performance and application fields of these two resins may also change. Therefore, we need to pay close attention to the development trend of the industry in order to adjust and respond to market changes in a timely manner.
