With the development of technology, the application of polyvinyl chloride (PVC) in various fields is becoming increasingly widespread. As an important synthetic material, PVC has attracted much attention due to its excellent properties and diverse forms. PVC products usually include PVC paste resin and PVC powder, although they are both made of polyvinyl chloride, they have some obvious differences

PVC paste resin is a white solid made by mixing PVC resin with plasticizers and other auxiliary agents, and using a thermal polymerization process. It has excellent fluidity and processability, and can be adjusted to different viscosities and rheological properties as needed. Polyvinyl chloride resin is commonly used in the production of adhesives, inks, coatings, and other products, as well as in the coating and processing of plastic products

In contrast, PVC powder is a powdered material made from PVC resin through mechanical crushing, grading, and screening processes. It has a larger particle size and lower viscosity, making it suitable for processing methods such as molding and extrusion. PVC powder is commonly used to manufacture hard plastic products, such as pipes, sheets, wire and cable sleeves, etc. It can also adjust physical properties such as color, transparency, and hardness by adding various additives and pigments

In terms of physical properties, there are also some differences between PVC paste resin and PVC powder. Due to the use of thermal polymerization technology, polyvinyl chloride paste resin has a high degree of intermolecular crosslinking, resulting in high mechanical strength and heat resistance. Due to differences in technology, PVC powder has a lower degree of crosslinking, resulting in better toughness and impact resistance. According to different usage environments and requirements, suitable materials can be selected

In terms of application, PVC paste resin and PVC powder also have their own advantages. Polyvinyl chloride resin, due to its excellent fluidity and processability, is commonly used in the production of films, tapes, coatings and other products, as well as in the production of primers and packaging materials. PVC powder, due to its good toughness and strength, is often used in the manufacturing of products with high durability requirements such as pipes, doors and windows, wire and cable sleeves, etc

In summary, there are significant differences in manufacturing processes, physical properties, and applications between PVC paste resin and PVC powder. Understanding these differences helps us better choose suitable materials to meet the requirements of different fields and needs. In the future, with the advancement of technology, the application fields of these two materials will continue to expand, making greater contributions to the development of various industries.
