In the 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 the 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.
In the packaging industry, this PVC resin can be processed into packaging film and rigid sheet. 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 sterilizable. 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 the consumer goods sector, 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, for example, vinyl chloride monomer is dispersed into fine droplets in an aqueous phase with the help of a dispersant. Simultaneously, polymerization occurs under the auspices 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 resin’s particle morphology and molecular weight distribution, which in turn determine the final product’s performance and application prospects.
