Polyvinyl chloride (PVC) resin appears as a white thermoplastic powder produced by the suspension polymerization process. It is insoluble in water, gasoline, and ethanol, but soluble in ketones, dichloromethane, and aromatic hydrocarbons. PVC resin features good chemical resistance, corrosion resistance, and dielectric properties. With appropriate additives (e.g., plasticizer and stabilizer), it can be converted into a wide range of finished products with tailored physical and mechanical properties. Based on the degree of polymerization, PVC suspension resin is categorized into 8 general grades, ranging from SG-1 to SG-8.
PVC Matting Resin SG-5
Pvc Matting Resin Sg 5 is a medium-polymerization grade Pvc Suspension Resin developed for applications that require both matte surface performance and balanced mechanical strength.PVC Matting Resin SG-5 is the most widely used and cost-effective general-purpose grade, with an average degree of polymerization of around 1000(981-1135). It offers a well-balanced combination of processability and mechanical strength, making it suitable for extrusion, injection, and calendering applications. Its versatility and competitive pricing make it an ideal material choice for a broad range of rigid and flexible PVC products.Matting SG-5 is a modified SG-5 grade added matting agent, featuring a smooth, matte appearance while maintaining all properties of SG-5.
Dingnuo provides Pvc Matting Resin Sg 5 for manufacturers seeking stable processing behavior, uniform resin quality, and attractive low-gloss finishes in PVC products. This resin grade is suitable for decorative and industrial applications where appearance, durability, and processing efficiency are equally important.
The processing characteristics of Pvc Matting Resin Sg 5 allow manufacturers to use it across various PVC production methods:
To maintain the quality and stability of Pvc Matting Resin Sg 5, appropriate storage and handling practices are recommended:
It is commonly used for decorative PVC products requiring matte surfaces, balanced rigidity, and stable processing performance.
SG5 generally provides higher rigidity and dimensional stability, while SG3 is more suitable for softer flexible applications.
Yes, it is widely used in decorative films, sheets, coated materials, and semi-rigid PVC products with matte finishes.
Yes, the resin supports extrusion, calendering, compounding, and coating processes depending on formulation requirements.
Dingnuo offers product guidance and application support to help customers optimize processing and material selection.
The resin should be stored in a dry, ventilated environment away from moisture, heat, and direct sunlight.
