Hygain offers a comprehensive portfolio of PVC resin grades designed to meet different processing requirements and end-use applications. The main product models include HS-700, HS-800, HS-1000F, HS-1000R, and HS-1300.
S-700 and HS-800: Suitable for general-purpose rigid PVC applications, including injection-molded products, profiles, and extruded products requiring balanced processability and mechanical performance.
HS-1000F and HS-1000R: Widely used in pipe, fitting, and window profile production, offering good rigidity, dimensional stability, impact strength, and stable extrusion performance.
HS-1300: Features higher viscosity and faster plasticizer absorption characteristics, making it suitable for flexible PVC applications such as films, artificial leather, soft sheets, cable compounds, and coated fabrics.
1. Excellent processing performance: Hygain PVC resin features uniform particle size distribution and stable porous structure, allowing rapid plasticizer absorption and efficient processing. The material performs well in extrusion, injection molding, calendaring, and various PVC compounding applications.
2. Outstanding chemical resistance: The resin offers strong resistance to acids, alkalis, salts, and many chemical substances, making it suitable for chemical piping systems, drainage applications, industrial sheets, and corrosion-resistant products.
3. Good mechanical strength and dimensional stability: Grades such as HS-1000R (SG-5 type) provide excellent balance of rigidity, impact strength, and dimensional stability, supporting reliable performance in PVC pipes, fittings, window profiles, and construction materials.
4. Reliable electrical insulation properties: PVC naturally provides good dielectric performance, making Hygain PVC resin suitable for wire and cable insulation compounds as well as electrical and electronic applications.
5. High whiteness and low impurity content: This resin is supplied as a clean white powder with effective control of fish eyes and impurities, helping manufacturers achieve consistent appearance quality and improved finished-product performance.
– Construction industry: Hygain PVC resin has a wide range of uses. It can be processed into PVC pipes and fittings for building water supply and drainage systems. Its excellent corrosion resistance and mechanical strength ensure the stability and safety of pipes during long-term use. In door and window manufacturing, it can be made into PVC door and window profiles, which offer thermal insulation, sound insulation, and excellent sealing properties, helping to improve the overall energy efficiency of buildings. It can also be used to produce PVC flooring and decorative panels, meeting the aesthetic and durability requirements of interior decoration.
– Packaging industry: Hygain PVC resin can be processed into packaging films and rigid sheets. PVC film has excellent barrier properties, effectively blocking oxygen and moisture vapor, protecting the contents from external environmental influences. It is commonly used for packaging products such as food, medicine, and cosmetics. PVC rigid sheet can be thermoformed into various packaging containers, such as blister packs, for packaging electronic components and small hardware items, providing both product display and securement.
– Medical field: Some Hygain PVC resin grades meet medical-grade standards and can be used to manufacture medical supplies such as IV tubing, blood bags, and urinary catheters. These medical products require materials that are non-toxic, chemically resistant, and easily sterilized. Hygain PVC resin precisely meets these requirements, ensuring safety and reliability during medical use.
– Other applications: In agriculture, it can be made into agricultural film, covering fields to insulate, retain moisture, and promote crop growth. In the toy industry, injection molding and other processes can be used to create brightly colored, tactile, and relatively affordable toys. In consumer goods, it is used to make rain boots, handbags, luggage, and other products to meet people’s daily needs.
The main production processes include suspension polymerization, emulsion polymerization, and bulk polymerization, with suspension polymerization being the most widely used. In suspension polymerization, vinyl chloride monomer is dispersed into fine droplets in an aqueous phase with the help of a dispersant. Simultaneously, polymerization occurs under the action of an initiator. During this process, precise control of key parameters such as reaction temperature, pressure, and initiator dosage ensures the production of Hygain PVC resin that meets quality standards. Different production processes affect the resinu2019s particle morphology and molecular weight distribution, which in turn determine the final productu2019s performance and application prospects.
