Unplasticized polyvinyl chloride (U-PVC), also known as rigid PVC, is a versatile and durable material widely used in construction and other industries due to its robust properties. Here’s a detailed look at U-PVC’s characteristics across mechanical, thermal, chemical, and electrical domains:

Mechanical Properties:

  • High Tensile Strength: U-PVC has good tensile strength, typically around 50-75 MPa, which makes it suitable for applications requiring rigidity and durability.
  • Impact Resistance: While generally less flexible than plasticized PVC, U-PVC offers good impact resistance, which can be enhanced through additives or co-extrusion processes.
  • Hardness and Stiffness: U-PVC is known for its hardness and high modulus of elasticity, making it resistant to deformation under load.

Thermal Properties:

  • Thermal Stability: U-PVC has excellent thermal stability and can withstand temperatures up to 60°C without significant thermal deformation.
  • Low Thermal Conductivity: U-PVC is a poor conductor of heat, making it an excellent choice for applications like window frames and pipes where insulation properties are important.

Chemical Properties:

  • Chemical Resistance: U-PVC is resistant to many acids, alkalis, salts, and alcohols, making it suitable for chemical handling applications. However, it is susceptible to some organic solvents.
  • Corrosion Resistance: Due to its excellent resistance to oxidation and degradation, U-PVC is used extensively in outdoor applications and for underground pipes where corrosion resistance is critical.

Electrical Properties:

  • Electrical Insulation: U-PVC is an excellent electrical insulator, with a high dielectric strength and low conductivity, making it ideal for use in electrical conduits and insulation.
  • Dielectric Constant: It typically has a dielectric constant of 3-4, which remains stable over a range of frequencies.

Additional Properties:

  • Low Water Absorption: U-PVC absorbs very little water, which helps maintain its mechanical and electrical properties in humid conditions.
  • Flame Resistance: U-PVC is inherently flame retardant due to the presence of chlorine in the polymer matrix, although it can release hydrochloric acid fumes when burned.

 

Unplasticized polyvinyl chloride (U-PVC) rods are highly valued for their robustness, chemical resistance, and durability. These characteristics make them suitable for a wide range of applications across various industries. Here are some key uses for U-PVC rods:

Industrial Applications

  • Piping and Valves: U-PVC rods are often machined into components for industrial piping systems due to their excellent chemical resistance and low reactivity. They are used in chemical processing plants, water treatment facilities, and any application where corrosion would be a concern for metal components.
  • Pump Shafts and Components: Due to their strength and stiffness, U-PVC rods are suitable for fabricating non-corrosive pump parts and fittings used in the handling of acids, alkalis, and other corrosive fluids.

Construction and Building

  • Window and Door Frames: U-PVC’s rigidity and durability make it an excellent material for constructing window frames and door profiles that require minimal maintenance and provide good thermal insulation.
  • Fascias and Soffits: U-PVC rods can be used to create various trims and architectural details in buildings due to their resistance to weathering and decay.

Electrical Insulation

  • Cable Insulation: U-PVC is commonly used in the electrical industry to produce insulation for cables and wires. Its excellent insulation properties help prevent electrical accidents and ensure the longevity of the cables.

Marine Applications

  • Marine Fittings: The material’s resistance to saltwater corrosion makes U-PVC rods ideal for fabricating various components used in boats and other marine applications.

Medical Equipment

  • Medical Device Components: U-PVC’s non-toxic and easy-to-clean properties allow it to be used in medical environments for constructing components that need regular sterilization.

Additional Uses

  • Signage: Because U-PVC can be easily shaped and welded, it is also used for making durable signs and displays that can withstand outdoor elements.
