Critical Processing Warnings for Hostaform C 9021 XAP LS colored:
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 XAP 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.
