描述
Hostaform LX90Z is a UV stabilized, integrally colored POM-C (Polyoxymethylene Copolymer) injection molding grade with specialty metallic appearance, genuinely manufactured by Celanese and imported as original product. We supply this grade as an authorized distributor / trader, ensuring full traceability and access to official Celanese technical documentation.
This grade is a nominal 9 melt flow rate acetal copolymer stabilized for use where ultraviolet radiation exposure is to be encountered. The material is formulated to prevent discoloration, fading, chalking and mechanical property change in severe ultraviolet exposure.
The “LX” designation indicates metallic appearance, and “Z” indicates UV stabilized grade. This product, formerly called Celcon® UV90Z metallics, is available in many molded-in-color metallic colors formulated for the interior automotive market and other applications.
It is a very hard and rigid, heavy-metal free POM copolymer grade that exhibits outstanding chemical resistance (solvents, fuels & strong alkalis), hydrolysis resistance, fatigue resistance, creep resistance, moisture resistance, and stress cracking resistance. With regular stock availability, we support both trial orders and bulk shipments for automotive interior and other UV-exposed applications.

Critical Processing Warnings for Hostaform LX90Z:
Drying is Required: Drying is required to prevent poor appearance and performance of the part.
Gate & Mold Design: Achieving optimal finish for specialty metallic parts is dependent on proper drying, gate design, knit line locations, and special processing conditions.
Thermal Degradation: POM can decompose at high temperatures, releasing formaldehyde gas. Ensure adequate ventilation and avoid prolonged residence time in the barrel. Max. melt temperature 195°C.
Material Purity: Strictly avoid contamination with other polymers, as this will compromise the metallic appearance, UV stability, and overall performance.
Regrind/Recycled Material: Adding regrind is not recommended for this specialty grade. Re-processing may degrade the metallic appearance, UV stability, and flow 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.
