Processing Guidelines (Injection Molding)

The following injection molding parameters are recommended for Hostaform C 9021 XAP2 LS:

Critical Processing Warnings for Hostaform C 9021 XAP2 LS:

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

• Color Consistency: As a pre-colored grade, ensure processing equipment is clean to avoid color contamination. Color stability is enhanced by UV stabilization.

• Material Purity: Strictly avoid contamination with other polymers, as this will compromise the low-emission properties, UV stability, and color consistency.

• Regrind/Recycled Material: Adding regrind is not recommended for this low-emission specialty grade. Re-processing may introduce additional volatile compounds and compromise XAP2 low emission properties and color consistency. 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 and color stability.
