描述
Hostaform H100 is a high viscosity, unfilled POM (Polyoxymethylene) homopolymer injection molding grade, 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.
Recently added to Celanese’s industry-leading POM product line, Hostaform H100 is the company’s first true homopolymer polyacetal material, complementing the existing Hostaform and Celcon acetal copolymer product offerings.
As a homopolymer, H100 offers superior mechanical properties compared to polyacetal copolymers, delivering an exceptional combination of high strength, high stiffness, and high toughness.
It is widely used in applications such as gears, automotive door systems, bushings, housings, rollers, and conveyor belts. With regular stock availability, we support both trial orders and bulk shipments.

Critical Processing Warnings for Hostaform H100:
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.
Drying is Recommended: Drying is recommended to achieve optimal processing and part quality. Recommended drying: 100°C for 3-4 hours in a dehumidified dryer.
Material Purity: Strictly avoid contamination with other polymers, as this will compromise the homopolymer properties and overall performance.
Regrind/Recycled Material: Adding regrind is not recommended for this homopolymer grade. Re-processing may degrade the molecular weight and compromise mechanical 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.
