Zhongtai Brand PVC Resin SG-5 - High-Performance SG-5 PVC Resin for Manufacturing and Construction

PVC Resin SG-5 is a versatile polyvinyl chloride resin widely used in the production of pipes, fittings, profiles, sheets, and other plastic products. Known for its excellent chemical stability, electrical insulation, and mechanical strength, SG-5 is suitable for both rigid and flexible applications. It is produced through the suspension polymerization process, ensuring high purity and consistent quality. With good processability and durability, PVC Resin SG-5 is a reliable choice for industrial, construction, and consumer goods manufacturing.

Product Overview

Basic Information: The chemical name of PVC resin SG-5 is polyvinyl chloride resin, the molecular formula is ((-CH_2 - CHCl - )_n), the CAS number is 9002-86-2, and the implementation standard is GB 5761-2006. It has the appearance of white powder, non-toxic and odorless. 

Relationship between molecular structure and performance: SG-5 type PVC resin has a medium molecular weight and a degree of polymerization of about 1000-1200. This molecular structure gives it good physical and chemical properties, including excellent mechanical strength, chemical corrosion resistance and good thermal stability.

Performance Characteristics

Excellent fluidity: It can also show good fluidity at low temperatures and is suitable for a variety of processing methods, such as injection molding and extrusion molding.

Good mechanical properties: It has high impact resistance and tensile strength, and can maintain a stable structure in harsh environments.

Excellent corrosion resistance: It can resist the erosion of a variety of chemical substances and is suitable for packaging materials in the chemical, pharmaceutical and other industries. Excellent processing adaptability: Whether it is hot forming or cold forming, it can meet the requirements of various processing techniques and help reduce production costs.

Other characteristics: good electrical insulation performance, non-flammable, low water absorption and good anti-aging ability.

Application field

Construction industry: often used in the production of pipes, window frames, wall panels and other building materials, with good sound insulation and heat preservation effects.

For example, PVC pipes are widely used in water supply, drainage and cable protection; PVC profiles are used in door and window frames, which can effectively reduce heat loss. Packaging field: can be used to manufacture packaging materials, including films and rigid packaging.

PVC films produced with SG-5 have high transparency and good barrier properties, and are often used for food and drug packaging; rigid packaging is mostly used for shell protection of electronic products and toys. 

Electronic industry: Due to its excellent electrical insulation performance, it is widely used in the insulation layer and sheath materials of wires and cables.

PVC cables have the characteristics of strong fire resistance, corrosion resistance and stable mechanical properties, and are important materials in power transmission and communication lines. Other fields: can also be used to manufacture daily consumer goods such as toys, soles and medical devices.

Its versatility and ease of processing enable it to meet the manufacturing needs of a wide range of products. Production process 4 Suspension polymerization is the main method for producing SG-5 type PVC resin. 

The advantages of this method are that the reaction conditions are easy to control, the product quality is stable, the particles are uniform, and it is suitable for large-scale industrial production.

Packaging and storage 3 It is usually packaged in 25kg PP bags. When storing, care should be taken to protect it from weathering, store it in a dry place, avoid extreme temperature fluctuations, and seal the bag after use to prevent moisture absorption and contamination.
