PEEK is a strong and stiff thermoplastic material that is often used in applications where performance at elevated temperatures is required. PEEK has outstanding chemical resistance as well as resistance to steam and hot water.

Specifications:

Flame retardance, Heat resistance, Anti-static, Dimension stability

Polyetheretherketone(PEEK) is  a cristalline high performance polymer with outstanding heat resistance, excellent strength and thermal properties.

PEEK can compete with metals in lots of fields, its uniquely structure and properties offer outstanding fatigue and abrasion resistance, self-lubricated, excellent electrical properties, radiation resistance, and can with outstand extreme temperatures difference environments.

PEEK is highly used in electronics and electrical, automotives, mechanical, chemical, aerospace, military, and many high-end industries.

PEEK injection molding technological conditions:

The pretreatment of raw materials: drying

1,Requirements must be fully dry, and when the production requires the use of a drying hopper.

2,Drying conditions: ordinary air circulation oven and equipment dryer hopper, 150 ℃ for 5 hours.

Injection molding conditions
Main points:

1,PEEK in high temperature molding process, good thermal stability, degradation rate on temperature, shear rate and high temperature retention time insensitive.Therefore, in the process of high temperature materials and desirable high-speed injection, mold temperature control should be uniform.

2,PEEK is a crystalline plastics, therefore making it fully crystalline can improve its performance, a general mold temperature at 160 ℃ can fully crystalline, even without heat treatment can obtain very good product.If the mold temperature is low or high performance, in 200 ℃ for 1 hour..

Mold and other matters needing attention

1,Because PEEK‘s high viscosity, nozzle, sprue,runner should take a larger value, to reduce the flow of pressure drop.

2,Mold and equipment shall not have sharp edges, grooves, each corner smooth transition.

3,Mold design must have good exhaust system..

4,Product design should avoid sharp corners, with circular arc transition.

5,Mold design and manufacture must be sufficiently efficient heating system and heat insulation system, to ensure that the mold temperature can be heated to 160 ℃.

PEEK  Injection process parameters

PS:

(1)Release agent must choose high temperature resistant release agent.

(2)The nozzle must be a heating system, to ensure that the temperature can be regulated, cylinder inlet need good cooling.
