Beiyuan PVC is a polyvinyl chloride resin product manufactured by Shaanxi Beiyuan Chemical Industry Group Co., Ltd. As a versatile thermoplastic material, it serves as a raw material for construction products, electrical components, industrial materials, and various plastic goods.

The product range includes general-purpose suspension PVC grades such as SG-3, SG-5, SG-7, and SG-8. Each grade has distinct polymerization characteristics that influence its processing behavior and suitability for specific formulations. Manufacturers can select the appropriate grade according to their production methods, product specifications, and performance requirements.

Product Characteristics

  1. Versatile Processing Options. Beiyuan PVC resin can be processed through extrusion, injection molding, and calendering. Grade selection and formulation adjustments help manufacturers meet different production requirements.
  2. Adjustable Material Properties. PVC formulations can produce rigid or flexible products. Stabilizers, lubricants, plasticizers, and modifiers help control hardness, flexibility, impact resistance, and processing performance.
  3. Chemical and Electrical Properties. PVC offers resistance to many acids, alkalis, and salt solutions, along with good electrical insulation. Its suitability for a particular application depends on the operating environment, formulation, and finished-product design.

How to Select the Right Grade

  • For PVC pipes and window profiles: Evaluate SG-5 and verify its suitability against the relevant product specifications.
  • For cable compounds, hoses, and artificial leather: Consider SG-3, with particular attention to plasticizer absorption and flexible-compound performance.
  • For sheets and packaging-related products: Evaluate SG-7 or other suitable grades according to forming conditions, surface quality, and applicable regulations.
  • For fittings, sheets, and foam boards: Consider SG-8 or another appropriate grade, subject to formulation and equipment trials.
  • For matte-finish products: Ask about Beiyuan’s matting-grade PVC resin series and confirm the specifications of the relevant model.
