1. Temperature Check: Ensure that the injection molding machine can reach a temperature of 400°C and the mold can reach 230°C.

2. Material Selection: Choose appropriate flowing PEEK raw materials based on the product structure.

  1). PEEK3600G: High fluidity, suitable for thin-walled products.

  2). PEEK5600G: Medium fluidity, suitable for standard products.

  3). PEEK7600G: Low fluidity, suitable for products requiring high toughness, such as screws.

JUNDE PEEK has excellent chemical resistance, often referred to as corrosion resistance. The high benzene ring content in its structure allows it to withstand most chemical agents, such as gasoline, kerosene, lubricants, formic acid, acetic acid, hydrochloric acid, caustic soda, and hydrogen peroxide. It does not tolerate strong oxidizing acids like concentrated sulfuric acid, concentrated nitric acid, aqua regia, and chlorine.

· Glass Transition Temperature (Tg): Approximately 143°C (289°F).

· Melting Point: Around 343°C (662°F).

· Operating Temperature: Some grades can operate up to 250°C (482°F).

· Thermal Stability: Highly resistant to thermal degradation and attacks from organic and aqueous environments.

The operating temperature of PEEK extends down to at least −70°C (−94°F). Like most plastics, PEEK becomes more brittle at extremely low temperatures.

PEEK is a semi-crystalline polymer with a glass transition temperature of 143°C and a melting temperature of 343°C.

Yes, PEEK is a thermal insulator, which means it does not easily conduct heat to nearby materials. It is also an excellent electrical insulator, making it useful in various medical applications.

Key PEEK degradation products appear at 450°C. At temperatures above 650°C, chain scission at terminal carbonyls is believed to be the primary pyrolysis pathway. Phenol is identified as a significant decomposition product, with a yield greater than benzene at temperatures over 650°C.

Polyetheretherketone (PEEK) is a semi-crystalline thermoplastic known for its excellent mechanical and chemical properties. It resists chemicals, radiation, water absorption, and wear while offering thermal stability at temperatures up to 480°F.
