Hostaform LX270 – High Flow POM-C with Metallic Appearance

描述

Hostaform LX270 is a high flow, pre-colored POM-C (Polyoxymethylene Copolymer) injection molding grade with molded-in 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 27 melt flow rate acetal copolymer, specially designed to provide excellent molded-in metallic appearance. It is available in a range of pre-colored metallic colors, eliminating the need for secondary painting operations.

The “LX” designation indicates high flow + metallic appearance, making it ideal for applications requiring both aesthetic appeal and processing efficiency. The “270” refers to the nominal melt flow rate of 27.

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. It also exhibits toughness down to -40°C, good heat distortion temperature (up to 90°C), very good slip/wear properties, excellent resilience, and low moisture absorption. With regular stock availability, we support both trial orders and bulk shipments for automotive, consumer electronics, and industrial applications.

Processing Guidelines (Injection Molding)

The following injection molding parameters are recommended for Hostaform LX270:

Critical Processing Warnings for Hostaform LX270:

• Drying for Optimal Finish: Proper drying is critical to achieve the optimal metallic finish. Recommended drying: 100°C for 3-4 hours in a dehumidified dryer.

• 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 220°C.

• Gate Design: Achieving optimal finish for specialty metallic parts is dependent on proper gate design, knit line locations, and special processing conditions.

• Material Purity: Strictly avoid contamination with other polymers, as this will compromise the metallic appearance and overall performance.

• Regrind/Recycled Material: Adding regrind is not recommended for this specialty grade. Re-processing may degrade the metallic appearance 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.
