Processing Guidelines (Injection Molding)

Recommended processing parameters for Hostaform MT12U03:

Critical Processing Warnings for Hostaform MT12U03:

• Fast Cycling Capability: With moderately high flow (MVR 12 cm³/10min), Hostaform MT12U03 is designed for faster cycling and thin walled parts. Adjust cycle parameters to maximize throughput while maintaining part quality.

• Drying: Drying is recommended for this medical grade material to achieve optimal performance and part quality. If material has come into contact with moisture through improper storage or handling, drying is necessary to prevent splay and odor.

• Medical Grade Purity: Strictly prevent cross‑contamination with other polymer grades or non-medical materials. Contamination will compromise the medical compliance and biocompatibility of the material.

• Thermal Degradation Risk: POM‑based material can decompose under excessive heat and release formaldehyde vapors. Guarantee sufficient ventilation; avoid overly long barrel residence times.

• Regrind / Recycled Material Notice: We do not recommend adding regrind for this medical grade specialty material. Reprocessing may compromise the biocompatibility, mechanical properties, and medical compliance. If regrind usage is mandatory, keep percentage below 10% and complete pre‑validation testing first.

• Storage Guidance: Store pellets in cool, dry conditions; keep sealed in original factory packaging whenever possible to maintain low residual monomer content.
