Hostaform C 9021 MD – Metal Detectable POM-C for Food & Pharma

描述

Hostaform C 9021 MD is a metal detectable POM-C (Polyoxymethylene Copolymer) injection molding material, 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 reinforced with approximately 6% stainless steel fibers [5†L14], providing the unique capability of being identified by metal detectors [0†L6-L7][0†L9-L11][3†L13-L14]. This makes it the ideal material for applications where product contamination must be prevented.

The “MD” designation stands for Metal Detectable, indicating that parts molded from this material can be detected and sorted by standard metal detection equipment.

It is a very hard and rigid, heavy-metal free POM copolymer grade that retains the outstanding chemical resistance, toughness, and dimensional stability of standard POM-C. With regular stock availability, we support both trial orders and bulk shipments for food processing, pharmaceutical, packaging, and other contamination-sensitive industries.

Processing Guidelines (Injection Molding)

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

Critical Processing Warnings for Hostaform C 9021 MD:

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

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

• Stainless Steel Fiber Orientation: Consider the orientation of stainless steel fibers in the mold design, as fiber orientation may affect detectability and mechanical properties.

• Regrind/Recycled Material: Adding regrind is not recommended for this metal detectable grade. Stainless steel fibers can degrade and segregate during re-processing, compromising metal detectability and 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.
