Polypropylene Homopolymer (PP-H)

General Information:

  • Product Name: Homopolymer Polypropylene (PP-H)
  • Classification: Thermoplastic Polymer


Typical Properties:

  • Density: 0.90 – 0.91 g/cm³
  • Melt Flow Rate (MFR): 1.5 – 40 g/10min (230°C/2.16kg, depending on grade)
  • Yield Strength: 30 – 35 MPa
  • Elongation at Break: 5 – 50%
  • Tensile Modulus: 1,500 – 1,700 MPa
  • Melting Point: 160 – 170°C
  • Vicat Softening Point: 140 – 155°C
  • Notched Izod Impact Strength: 2 – 5 kJ/m²
  • Heat Deflection Temperature (0.46 MPa): 100 – 110°C
  • Coefficient of Linear Thermal Expansion: 150 x 10^(-6) K^(-1)


Features and Benefits:

  • High Rigidity: Stiffer than other types of polypropylene.
  • High Temperature Resistance: Suitable for applications that require elevated temperature performance.
  • Good Chemical Resistance: Resistant to most inorganic acids, alkalis, and salts.
  • Electrical Insulation: Exhibits excellent electrical insulation properties.
  • Weldability: Can be welded using various welding methods.



  • Chemical Containers: Tanks, vessels, and pipework for chemical storage and transport.
  • Automotive: Battery cases, under-the-hood components.
  • Consumer Goods: Appliances, furniture components.
  • Packaging: For products that need stiffer packaging solutions.
  • Building and Construction: Piping systems, roofing membranes.
  • Electrical Components: Housings, electrical insulators.


Processing Methods:

  • Extrusion (sheets, films, pipes)
  • Injection Molding (components, parts)
  • Thermoforming (large parts, containers)
  • Welding and Joining


Environmental Impact and Recycling:

  • PP-H is recyclable and can be reprocessed into new products.
  • It doesn’t readily absorb water, which reduces energy used in drying for recycling processes.
  • Should be separated from other plastics when recycling to maintain polymer properties.


Storage and Handling:

  • Store in a cool, dry place, away from direct sunlight.
  • Avoid prolonged exposure to high temperatures.
  • Handle with care to avoid surface damage or scratches.


Safety Information:

  • Generally recognized as safe for various consumer and industrial applications.
  • When processing or welding PP-H, ensure the area is well-ventilated to prevent inhalation of fumes.
  • PP-H has a low flammability but will burn in the presence of open flames, releasing carbon monoxide and water.

Note: This technical data sheet provides general information and typical values for PP-H. The actual specifications can differ based on the manufacturer and the specific product grade. Always refer to manufacturer-specific data sheets for detailed information on a particular product.
