Hostaform C 9021 GV3/30 TF2 – 30% Glass Bead Reinforced PTFE-Modified POM-C

描述

Hostaform C 9021 GV3/30 TF2 is a high-performance glass bead reinforced 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 30% glass spheres (glass beads) and further modified with PTFE (polytetrafluoroethylene) for enhanced tribological performance.

The “GV3/30” designation indicates glass bead reinforcement at 30% loading, providing ultra-low warpage and isotropic (uniform) shrinkage. The “TF2” suffix denotes tribological modification with PTFE, delivering low friction, excellent wear resistance, and self-lubricating properties.

It combines very high rigidity and hardness with outstanding dimensional stability, low warpage, and excellent slip/wear characteristics. With regular stock availability, we support both trial orders and bulk shipments for precision engineering, automotive, electrical, and high-performance sliding applications.

Material Advantages

The following material advantages make Hostaform C 9021 GV3/30 TF2 the preferred choice for precision, low-warpage, and low-friction applications:

• Glass Beads + PTFE – The Ideal Combination – Unlike glass fiber reinforced grades (GV1 series) which can cause anisotropic shrinkage, the spherical glass beads in GV3/30 TF2 provide isotropic shrinkage and ultra-low warpage, while the PTFE modification adds low friction and excellent wear resistance – a combination unmatched by standard glass-filled grades.

• Superior Dimensional Stability – The combination of low warpage, isotropic shrinkage, and low moisture absorption ensures parts maintain their dimensions across varying environmental conditions.

• Excellent Surface Quality – Glass bead reinforcement produces a much smoother surface finish compared to glass fiber grades, reducing the need for secondary finishing operations.

• Outstanding Chemical & Environmental Resistance – Excellent resistance to solvents, fuels, strong alkalis, hydrolysis, fatigue, creep, moisture, and stress cracking.

• High Toughness – Maintains impact resistance and toughness even at low temperatures (down to -40°C).

• Good Thermal Stability – Higher stability to thermal and oxidative degradation compared to acetal homopolymers.

• Self-Lubricating – PTFE modification provides inherent lubricity, reducing friction and wear in moving parts.

• Easy Colorization – Can be easily colored to meet specific design requirements.

• Heavy-Metal Free – Environmentally friendly formulation.

• Batch-to-Batch Consistency – Produced by Celanese under strict ISO standards, ensuring stable properties across all shipments.

• Reliable Supply – We maintain inventory and a stable supply chain. For details on our supply capabilities, please see our company background .

Important Notes on Typical Data:

1. Values listed are typical and based on Celanese official data sheets. They do not constitute a product specification.

2. Batch-to-batch variations may occur. Confirm properties with specific batch certificate for critical applications.

3. Final product performance depends on part design, molding conditions, and end-use environment.

Processing Guidelines (Injection Molding)

The following injection molding parameters are recommended for Hostaform C 9021 GV3/30 TF2:

Critical Processing Warnings for Hostaform C 9021 GV3/30 TF2:

• 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 glass bead reinforced and PTFE-modified properties.

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

• Mold Design: The glass bead reinforcement provides isotropic shrinkage, but proper gating and venting are still recommended for optimal part quality.

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

Hostaform C 9021 GV3/30 TF2 FAQ

Q1: What is Hostaform C 9021 GV3/30 TF2 and what is it used for?
A: It is a 30% glass bead reinforced POM-C (Polyoxymethylene Copolymer) injection molding material with PTFE tribological modification for low friction and excellent wear resistance. Unlike glass fiber reinforced grades, it offers ultra-low warpage and isotropic (uniform) shrinkage, making it ideal for precision components requiring tight dimensional tolerances, excellent surface finish, and good sliding properties. It is widely used in precision engineering, automotive, electrical & electronics, industrial components, and consumer goods.

Q2: What does “GV3/30 TF2” mean in the grade name?
A: GV3 indicates Glass Bead Reinforced Version 3 (using glass spheres rather than glass fibers). /30 indicates approximately 30% glass bead content by weight. TF2 indicates tribological modification with PTFE for low friction and wear resistance. The resin identification code is (POM+PTFE)-GB30.

Q3: What is the difference between GV3/30 TF2 and GV3/30 (without TF2)?
A: Both grades have the same 30% glass bead content and low warpage characteristics. The key difference is the “TF2” PTFE modification, which adds low friction, excellent wear resistance, and self-lubricating properties to GV3/30 TF2. Choose TF2 for moving parts and sliding applications where friction and wear are concerns; choose standard GV3/30 for static precision components where tribological performance is not required.

Q4: What is the difference between GV3 (glass bead) and GV1 (glass fiber) reinforced grades?
A: GV3 series uses spherical glass beads which provide isotropic shrinkage and ultra-low warpage, resulting in excellent dimensional stability and smooth surface finish. GV1 series uses glass fibers which provide higher stiffness and strength but can cause anisotropic shrinkage and warpage. Choose GV3 for precision components with tight tolerances; choose GV1 for maximum structural strength.

Q5: What is the UL flammability rating?
A: UL94 HB rated. Please refer to the UL Yellow Card for specific thickness ratings.

Q6: Can I purchase this material and what is the lead time?
A: Yes, simply send your inquiry via our quick inquiry form or email us at ruiqingchem@gmail.com with your required quantity, application, and delivery address.
