What is PEEK Plastic Material

Changchun Jida PEEK 021GF30 is a glass fiber reinforced PEEK plastic material, specially designed for engineering components with high strength and high heat resistance.

Based on the inherent thermal stability, chemical inertness and mechanical toughness of PEEK resin, 30% glass fiber reinforcement endows the material with higher structural rigidity and dimensional stability, enabling it to maintain stable performance under harsh working conditions.

This material has passed the UL94 V-0 flame retardant grade and features excellent heat distortion temperature and low water absorption rate. It is suitable for industries such as electronics, electrical appliances, automobiles, and medical care, which have extremely high requirements for heat load and precision.

05 | Frequently Asked Questions (FAQ)

Q1: What are the differences between PEEK 021GF30 and unreinforced PEEK?

A: 021GF30 contains 30% glass fiber reinforcement. Its mechanical strength, rigidity and heat resistance are significantly higher than those of pure resin-based PEEK, but its toughness is slightly lower accordingly, making it more suitable for structural components.

Q2: Can this material be used for food or medical contact?

A: This model is mainly designed for industrial and electronic applications. If medical-grade or contact applications are required, medical-certified PEEK models can be selected.

Q3: How difficult is the processing of PEEK 021GF30?

A: Good processability and moderate fluidity. A slightly higher mold temperature compared to conventional PEEK can achieve better crystallinity and dimensional accuracy.

Q4: Can it replace metal parts?

A: In most high-temperature environments, it can replace aluminum or stainless steel components with a lighter weight and stronger chemical resistance, achieving structural optimization and cost savings.
