Processing Guidelines (Injection Molding)

The following injection molding parameters are recommended for Hostaform C 9021 XAP C:

Critical Processing Warnings for Hostaform C 9021 XAP C:

• Thermal Degradation: POM can decompose at high temperatures, releasing formaldehyde gas. Ensure adequate ventilation and avoid prolonged residence time in the barrel.

• Material Purity: Strictly avoid contamination with other polymers, as this will compromise the low-emission properties and overall performance.

• Regrind/Recycled Material: Adding regrind is not recommended for this low-emission specialty grade. Re-processing may introduce additional volatile compounds and compromise the XAP low emission properties. If necessary, use a very small percentage (<10%) only with prior validation testing.

• Storage: Store in a cool, dry place and use sealed, original packaging when possible to maintain low-emission characteristics.
