What is PEEK Engineering Plastic

HiFill® 450 A is a PEEK engineering plastic launched by Techmer PM. It belongs to the PEEK-FR series and is specially developed for high-temperature, flame-retardant and chemically resistant working conditions.

As a pipe-grade material, it combines UL94 V-0 flame retardancy grade with stable structural strength, and performs exceptionally well in electrical equipment, industrial pipelines and automotive components.

PEEK (Polyether Ether Ketone) is a high-performance engineering plastic, which is widely used in aviation, energy and medical fields due to its excellent thermal stability, mechanical strength and dimensional stability. PEEK 450 A, while maintaining the core performance of PEEK, optimizes flame retardancy and processing fluidity, making it more suitable for the molding of complex structural parts.
