Hostaform C 9021 GV1/30 GT – 30% Glass Reinforced Tribological POM-C

描述

Hostaform C 9021 GV1/30 GT is a high-performance tribological 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 26% glass fibers and further modified with UHMWPE (ultra-high molecular weight polyethylene) for enhanced wear performance.

The “GV1/30” designation indicates glass fiber reinforcement at approximately 30% loading, providing exceptional strength and rigidity. The “GT” suffix denotes tribological modification, delivering significantly improved wear resistance and low friction for demanding moving-part applications.

It offers very high strength, rigidity, and hardness combined with excellent wear resistance and dimensional stability. With regular stock availability, we support both trial orders and bulk shipments for automotive, industrial machinery, precision engineering, and high-load sliding applications.

Processing Guidelines (Injection Molding)

The following injection molding parameters are recommended for Hostaform C 9021 GV1/30 GT:

Critical Processing Warnings for Hostaform C 9021 GV1/30 GT:

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

• Fiber Breakage: Avoid excessive screw speed or back pressure, as this can break glass fibers and reduce mechanical properties.

• Material Purity: Strictly avoid contamination with other polymers, as this will compromise the glass-filled and tribological properties.

• Regrind/Recycled Material: Adding regrind is not recommended for this specialty grade. Glass fibers and UHMWPE additives will degrade during re-processing, significantly compromising mechanical and tribological properties. If necessary, use a very small percentage (<10%) only with prior validation testing.

• Mold Design: Consider the orientation of glass fibers in the mold design, as fiber orientation affects shrinkage and mechanical properties in the flow direction.

• Storage: Store in a cool, dry place and use sealed, original packaging when possible.

Hostaform C 9021 GV1/30 GT FAQ

Q1: What is Hostaform C 9021 GV1/30 GT and what is it used for?
A: It is a 30% glass fiber reinforced POM-C (Polyoxymethylene Copolymer) injection molding material with UHMWPE-based tribological modification for enhanced wear performance. It delivers high strength (8700 MPa tensile modulus, 110 MPa tensile stress at break), excellent rigidity, and superior wear resistance. It is widely used in automotive engineering (fuel system components, structural housings, seat mechanisms), precision engineering (gears, cams, connectors), electrical & electronic components, industrial machinery, and consumer goods.

Q2: What does “GT” mean in the grade name?
A: GT stands for Tribological Grade. It indicates that the material is modified with UHMWPE (ultra-high molecular weight polyethylene) to provide specialty low wear performance, combining high rigidity with excellent abrasion resistance.

Q3: How does Hostaform C 9021 GV1/30 GT compare to standard GV1/30?
A: Both grades have similar glass fiber content and mechanical properties. The key difference is the “GT” tribological modification, which adds UHMWPE for significantly improved wear resistance and low friction, making it ideal for moving parts and sliding applications where standard GV1/30 would experience higher wear.

Q4: What are the regulatory compliances of this material?
A: Hostaform C 9021 GV1/30 GT complies with RoHS, PFOS and PFOA, and meets BgVV recommendation XXXIII for consumer goods. Full compliance declarations are available upon request.
