描述
PVC S65 (or S-65) is a general-purpose suspension polyvinyl chloride (PVC) resin with a medium degree of polymerization and a K-value of approximately 65. Produced using advanced suspension polymerization technology, it offers a well-balanced combination of processing performance, mechanical properties, and application versatility.
As one of the most widely used PVC grades, S-65 is suitable for both flexible and certain rigid applications, making it a key raw material in the plastics processing industry.

Product Features of PVC S65
Excellent Processability. PVC S-65 exhibits good thermoplastic behavior and melt flow characteristics, making it suitable for a wide range of processing methods, including extrusion, calendering, injection molding, and coating. It provides a wide processing window and stable operation in continuous production.
Good Plasticization Performance. The resin has strong compatibility with plasticizers and allows for uniform and efficient plasticization. This contributes to improved product appearance and consistent physical properties.
Balanced Mechanical Properties. Finished products made from S-65 resin offer a good balance between flexibility and strength, making them suitable for applications requiring both durability and softness.
Outstanding Chemical Resistance. PVC inherently provides excellent resistance to acids, alkalis, and corrosive environments, ensuring long-term durability in demanding conditions.
Excellent Electrical Insulation. The material offers reliable electrical insulation properties, making it suitable for wire and cable applications.
What Are The Primary Uses of S-65 Resin
Flexible Applications. PVC S65 is widely used in flexible applications, including wire and cable insulation and sheathing, flexible hoses and transparent tubing, artificial leather and synthetic leather, as well as films and packaging materials. It is also suitable for PVC flooring, where good flexibility and durability are required.
Coating & Dipping Products. In coating and dipping applications, S-65 is commonly used for the production of industrial and medical gloves, coated textiles, and various protective materials, offering reliable performance and consistent quality.
Semi-Rigid Applications. For semi-rigid applications, PVC S65 can be applied in injection-molded components and packaging containers, providing a balanced combination of strength and processability.
Safety and Environmental Information
PVC S65 resin is a stable polymer and is non-toxic under normal handling conditions. During high-temperature processing, proper ventilation is recommended to prevent exposure to decomposition by-products.
The product can comply with relevant environmental and safety standards such as REACH and RoHS, depending on the manufacturer.
