Properties of PP-EPDM Regranulate

PP-EPDM regranulate features an impressive set of technical and functional parameters that make it indispensable in projects requiring durability, flexibility and resistance. Thanks to the synergy of polypropylene and EPDM elastomers, the material achieves exceptional performance in demanding industrial conditions and precision-based applications.

Key Properties:

• Mechanical strength and deformation resistance
  The material provides high resistance to mechanical forces, minimising the risk of cracking and deformation. Its robustness makes it ideal for components exposed to dynamic loads, such as bumpers and insulation elements.
• Vibration damping and noise reduction
  PP-EPDM regranulate acts as a natural shock absorber, making it an excellent choice for seals, technical housings and other components used in noise-reduction systems.
• Chemical and weather resistance
  PP-EPDM withstands UV radiation, moisture and exposure to oils and chemicals such as alkalis and alcohols. This makes it invaluable in applications exposed to variable environmental conditions.
• Wide operating temperature range
  With reliable performance from -40°C to 120°C, PP-EPDM regranulate is suitable for low-temperature and high-temperature applications.

Processing of PP-EPDM Regranulate

The processing of PP-EPDM regranulate relies on strict control of technological parameters, ensuring high production efficiency and top-quality final products. Its recyclability not only reduces waste but also improves machine durability.

Optimal Processing Conditions:

• Processing temperature range:
  Recommended cylinder temperature: 220°C–240°C, supporting a uniform material structure.
• Precise injection pressure:
  Depending on the moulding requirements, the pressure should range between 600–1,000 bar.
• Shrinkage control:
  When designing components, consider material shrinkage at 1.2–1.8% to ensure perfect fit and dimensional accuracy.

Processing Benefits:

• Reduced production waste and lower manufacturing costs.
• Longer machine lifespan due to low deposits and anti-adhesive properties.
