Hostaform C 9021 AS POM-C |Antistatic Acetal Copolymer for Electronics

描述

Hostaform C 9021 AS is a permanently antistatic POM-C (Polyoxymethylene Copolymer) injection molding grade supplied by Celanese. This grade features low surface resistivity, providing reliable electrostatic discharge (ESD) protection for sensitive electronic components and cleanroom environments. It maintains the inherent mechanical strength, stiffness, and creep resistance of standard POM-C while adding permanent antistatic properties that do not migrate or wash off. With global stock availability and fast delivery, we support both sample orders and bulk shipments for electronics manufacturing, semiconductor handling, and precision mechanical applications.

Hostaform C 9021 AS POM-C Key Features

• Permanent Antistatic Performance – Low surface resistivity provides consistent ESD protection that does not depend on humidity or surface treatments.

• High Mechanical Strength – Retains the excellent stiffness, impact resistance, and creep resistance of standard POM-C.

• Low Friction & Wear Resistance – Self-lubricating properties reduce wear in moving parts, ideal for precision mechanisms.

• Good Dimensional Stability – Low moisture absorption ensures stable dimensions even in varying environmental conditions.

• Easy Processing – Suitable for injection molding of complex, precision components with consistent flow properties.

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

Hostaform C 9021 AS POM-C FAQ

Q1: What does “AS” stand for in Hostaform C 9021 AS?
A: “AS” stands for Antistatic. This grade is specifically formulated to provide permanent electrostatic discharge (ESD) protection for sensitive electronic components.

Q2: How is the antistatic property achieved?
A: The antistatic effect is built into the material through special additives. Unlike surface coatings, it is permanent, non-migrating, and does not depend on ambient humidity to function.

Q3: What is the typical surface resistivity of Hostaform C 9021 AS?
A: The typical surface resistivity ranges from 10⁹ to 10¹¹ ohms/sq (measured per IEC 60093), which is in the antistatic range suitable for most electronics handling applications.

Q4: Can this material be colored?
A: Yes, while the standard grade is natural (light-colored), it can be colored upon request. Please note that colorants may affect the antistatic properties and should be tested for your specific application.

Q5: Is this material suitable for cleanroom use?
A: Yes, it is suitable for cleanroom environments due to its low outgassing and permanent antistatic properties. Please consult the SDS and TDS for specific outgassing data.

Q6: Can I get free samples?
A: Yes, we support free samples of 500g–1kg for testing purposes, but international shipping costs must be covered by the customer. Please submit your sample request via our inquiry form .

Q7: What is the lead time for bulk orders?
A: Regular orders (1–5 tons) are shipped within 7–10 working days after order confirmation. For larger quantities, please consult our sales team for specific production scheduling.
