The wrong raw material leads to production losses, returns and performance problems. The six points below are the basic list to prepare before talking to a supplier.
- Mechanical requirements. Tensile strength, impact resistance, stiffness and fatigue. What load will the part carry, and how often?
- Thermal conditions. Continuous service temperature and short-term peaks. Check glass transition and heat deflection temperature values.
- Flow and processing. Melt flow index (MFI, commonly measured per ISO 1133 or ASTM D1238) must suit injection molding, extrusion or blow molding. A high MFI eases filling; a low MFI generally means higher toughness.
- Environment and chemicals. UV, moisture, oils and cleaning agents. Select UV-stabilized or flame-retardant grades when needed.
- Regulation and certification. Food-contact, medical or electrical and electronic applications require the relevant compliance documents.
- Supply continuity. Batch consistency, lead times and alternative grades. An inexpensive but inconsistent raw material can cost more in production.
Once your list is ready, browse the technical details on our product pages or send us your requirement, and we will identify suitable grades for your application together.
