Hostaform C 9021 GV3/30 – 30% Glass Bead Reinforced Low Warpage POM-C

描述

Hostaform C 9021 GV3/30 is a 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.

Unlike conventional glass fiber reinforced grades, this material is reinforced with approximately 30% glass spheres (glass beads) , delivering ultra-low warpage and isotropic (uniform) shrinkage properties.

The “GV3/30” designation indicates the highest glass bead loading in the GV3 series, providing maximum rigidity, hardness, and dimensional stability among glass bead reinforced POM grades.

It exhibits outstanding chemical resistance (solvents, fuels & strong alkalis), hydrolysis resistance, fatigue resistance, creep resistance, moisture resistance, and stress cracking resistance. It also maintains toughness down to -40°C and offers higher stability to thermal and oxidative degradation compared to acetal homopolymers. With regular stock availability, we support both trial orders and bulk shipments for precision engineering, automotive, and electronic applications.

Material Advantages

The following material advantages make Hostaform C 9021 GV3/30 the preferred choice for precision, low-warpage applications requiring maximum rigidity:

• Highest Rigidity in GV3 Series – With 30% glass bead content, this grade offers the highest rigidity and hardness among all GV3 grades, making it ideal for applications where maximum structural performance is required.

• Glass Beads vs. Glass Fibers – Unlike glass fiber reinforced grades (GV1 series) which can cause anisotropic shrinkage and warpage, the spherical glass beads in GV3/30 provide isotropic (uniform) shrinkage and ultra-low warpage.

• 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.

• 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.

4. Celanese original TDS remains the definitive reference. For detailed data, request the latest official TDS for Hostaform C 9021 GV3/30 from our team.

Processing Guidelines (Injection Molding)

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

Critical Processing Warnings for Hostaform C 9021 GV3/30:

• 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 properties and mechanical performance.

• Regrind/Recycled Material: Adding regrind is not recommended for this specialty grade. Glass beads can degrade during re-processing, compromising mechanical properties and dimensional stability. 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.

FAQ

Q1: What is Hostaform C 9021 GV3/30 and what is it used for?
A: It is a 30% glass bead reinforced POM-C (Polyoxymethylene Copolymer) injection molding material. Unlike glass fiber reinforced grades, it offers ultra-low warpage and isotropic (uniform) shrinkage making it ideal for precision components requiring tight dimensional tolerances and excellent surface finish. The 30% glass bead content provides the highest rigidity and hardness in the GV3 series. It is widely used in precision engineering, automotive (interior and under-the-hood components), electrical & electronics (connectors, switch housings), domestic appliances, and industrial components.

Q2: What does “GV3/30” mean in the grade name?
A: GV3 indicates Glass Bead Reinforced Version 3 (using glass spheres rather than glass fibers), and /30 indicates approximately 30% glass bead content by weight. The resin identification code is POM-GB30 (GB = Glass Beads).

Q3: 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.

Q4: What is the difference between GV3/10, GV3/20, and GV3/30?
A: GV3/30 contains 30% glass beads (the highest in the GV3 series), providing the highest rigidity, hardness, and dimensional stability. GV3/10 (10%) and GV3/20 (20%) offer progressively lower rigidity but slightly better impact resistance. Choose GV3/30 when maximum structural performance and dimensional stability are required.

Q5: What is the UL flammability rating?
A: UL94 HB rated. For natural color, thickness ≥0.81mm; for black color, thickness ≥1.0mm. FMVSS 302 burning rate is <100 mm/min for thickness >1mm.
