描述

Hostaform C 9021 G is a glass fiber 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 specifically formulated with glass fiber reinforcement to deliver significantly higher stiffness, improved heat deflection temperature, and enhanced dimensional stability compared to unreinforced POM grades.

The “G” designation indicates glass fiber content, which provides excellent load-bearing capacity and creep resistance for structural applications.

It maintains the chemical resistance and low friction properties of standard POM-C while offering superior mechanical performance. With regular stock availability, we support both trial orders and bulk shipments for automotive, industrial machinery, and high-load engineering applications.

Key Features

Hostaform C 9021 G offers the following key performance benefits:

  • Glass Fiber Reinforced – Provides high stiffness, improved heat deflection temperature, and excellent dimensional stability.

  • High Mechanical Strength – Significantly increased tensile strength and flexural modulus compared to unreinforced POM-C.

  • Excellent Creep Resistance – Maintains dimensional stability under long-term static loads, ideal for structural components.

  • Low Friction & Wear Resistance – Retains the self-lubricating properties of POM-C for moving parts.

  • Enhanced Dimensional Stability – Reduced mold shrinkage and thermal expansion for precision components.

  • Chemical Resistance – Resistant to a wide range of solvents, fuels, and chemicals.

  • Regulatory Compliance – Meets RoHS and REACH requirements. Full SDS available upon request.

Processing Guidelines (Injection Molding)

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

Parameter Recommended Setting & Critical Warnings
Pre-drying 80–100°C for 2–4 hours. Required to prevent surface silver streaks.
Barrel Temperature 190–220°C (Nozzle: 200–215°C).
Mold Temperature 80–120°C (Higher improves crystallinity and surface quality).
Injection Pressure 80–160 MPa (Medium-to-high for thin-wall filling).
Screw Speed Medium speed to avoid excessive shear degradation and fiber breakage.

Critical Processing Warnings for Hostaform C 9021 G:

  • 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 properties and mechanical performance.

  • Regrind/Recycled Material: Adding regrind is not recommended for this glass-filled grade. The glass fiber reinforcement is brittle and will degrade during re-processing, significantly compromising mechanical 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.

FAQ

Q1: What is Hostaform C 9021 G and what is it used for?
A: It is a glass fiber reinforced POM-C (Polyoxymethylene Copolymer) injection molding material that offers significantly higher stiffness, heat deflection temperature, and dimensional stability compared to unreinforced POM grades. It is widely used in automotive, industrial machinery, and structural applications where high load-bearing capacity and precision are required. Typical parts include structural housings, high-load gears, pump housings, valve bodies, and power tool components.

Q2: What does “G” mean in the grade name?
A: G stands for Glass Fiber Reinforced. This indicates that the material contains glass fiber reinforcement (typically 20-25%) to enhance stiffness, strength, and heat resistance.

Q3: How does Hostaform C 9021 G compare to standard POM-C?
A: The glass fiber reinforcement provides significantly higher tensile and flexural strength, increased heat deflection temperature (up to ~155°C), and reduced mold shrinkage. However, it has lower elongation at break and impact strength compared to unreinforced grades.

Q4: 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. Regular orders (1–5 tons) are typically delivered within 7–10 working days after order confirmation and payment receipt. Larger quantities or urgent orders can be discussed with our team.

Q5: What are the limitations of this material?
A: POM materials are not suitable for use with strong acids, strong oxidizing agents, or continuous high-temperature water (>80°C) . The glass-filled grade also has reduced impact strength compared to unreinforced grades and may be abrasive to molds and processing equipment. Please consult our technical team for specific application guidance.

Q6: What is the recommended storage and shelf life?
A: Store in original, sealed packaging in a cool, dry place away from direct sunlight. Typical shelf life is 12 months from manufacture under proper conditions. Once opened, use promptly or re-seal. Due to the glass fiber content, ensure packaging remains intact to prevent moisture absorption.
