Key features
Why this product?
- Observe fire safety rules for combustible materials. Lift adhesive-held bags first without rotation. If moisture condenses inside packaging, drying pellets before use is recommended.
- [2] Typical properties measured on standard injection-moulded specimens according to ISO 294-1. Not to be used as specification.
- User tests for suitability and regulatory compliance, including food contact are required.
- Exceptional mechanical-property balance, stiffness and impact resistance support long-lasting reliability, material optimization and cost-efficient down gauging.
- See DDS for product compliance and safety information.
- High humidity and fluctuating temperatures can cause condensation inside packaging.
- Polymers are exempt from REACH registration; monomers and relevant additives are registered.
- At source revision, no specifically identified SVHC >0.1%.
- Raw materials are REACH compliant.
- Suitable for modern recycling methods; keep in-house production waste clean for direct recycling.
- Heat-treated pooled pallets are collected for reuse and remain the provider’s property.
