Injection molding material datasheets
An injection molding material datasheet is a technical document that compiles the mechanical, thermal, and physical properties of a polymer, needed to define injection molding process parameters. PlastHub references 600+ material datasheets from 64 manufacturers (BASF Ultramid, DuPont Zytel, Covestro Makrolon, LANXESS Durethan, Solvay Amodel) with data standardized to ISO norms.

Material families
- Standard: PP, PE-HD, PE-LD, PS, ABS, SAN, ASA — the most widely used polymers in injection molding
- Engineering: PA6, PA66, PA12, POM, PBT, PC, PC/ABS, PET — high mechanical and thermal resistance
- High Performance: PEEK, PPS, PEI, LCP, PPA — critical applications (aerospace, medical)
- Elastomers: TPE, TPU, TPV, SEBS — flexibility and impact resistance
