Key features
Why this product?
- Can be processed on standard injection moulding machines. Combustible; observe fire rules for combustible materials in warehouses. If condensation occurs, drying pellets before use is recommended.
- Protect from UV and temperatures above 40 °C. 25 kg PE bags; shrink/stretch-wrapped pallets: 1375 kg polymer. Road or rail silo transportation is also available.
- [2] Standard injection moulded specimens per ISO 294-1. [12] Standard injection moulded specimens prepared by internal method. [F] Press moulded specimen: 356 × 73 × 2.1–2.4 mm; horizontal position. Typical values are not specifications.
- Compounding then injection moulding for automotive use; exceptional impact resistance below zero and very good impact/stiffness balance.
- Heavy applications often need no rubber modifier; blends allow more regranulate without loss of impact properties, making the material economically attractive.
- Applications are recommendations; users must test final-article suitability and regulations such as food contact.
- Processed on standard injection machines.
- Combustible; observe warehouse fire rules.
- High humidity and fluctuating temperatures may cause condensation inside packaging; dry before use if it occurs.
- Heat-treated pooled pallets are collected for reuse and remain the provider’s property.
- Suitable for modern recycling; keep in-house waste clean for direct recycling.
- Source: August 2025.
- Polymers are REACH-exempt; monomers/relevant additives registered.
- Only REACH-compliant raw materials used; no identified SVHC >0.1%.
- Product compliance/safety: DDS; MSDS on request.
- Exceptional high impact resistance even at minus temperatures and very good impact/stiffness balance.
- A rubber modifier is often unnecessary to improve impact performance in heavy applications.
- Blends allow higher regranulate content without deterioration of impact properties.
- Applications are recommendations; users must test suitability and regulatory compliance (e.g. food contact).
