Introduction:Key performance PEEK polymer
• High heat resistance - to withstand up to 260 C (500 F) continuous operating temperature.
• radiation resistance - after by high doses of ionizing radiation can still maintain characteristics.
• hydrolysis resistance - maintaining excellent mechanical properties and dimensional stability when exposed to water or high pressure steam.
• lubrication - self-lubricating and abrasion resistance.
• Chemical resistance - for a variety of types of chemical environment has excellent tolerability, even at high temperatures as well.
• Electrical properties - can maintain excellent stability over a wide frequency and temperature range.
Lichang developed products are pure PEEK resin, PEEK carbon fiber, PEEK composites, PEEK glass fiber reinforced, PEEK products series.

  •  PEEK KLC608主要性能参数

  • In auto parts, semiconductor industry, aerospace industry, petrochemical industry, machinery industry, medical industry, electronic appliances and so on the field has been widely used for the manufacture of: automotive brake system parts, engine parts, transmission temperature gaskets, semiconductor tools, LCD bracket, wafer turnover equipment, IC test equipment parts, copier separation claws, bushings, and other office supplies high-temperature components; special mechanical gear, oil-lubricated bearings, compressor valves, seals, piston rings, valve components, temperature sensor probe, special electronic connectors, analytical instrument parts, special cable sheathing, human bones, hemodialysis machine parts, lithium seals, integrated circuit film, irons, microwave ovens heat-resistant parts, and so on.
  • A.  the raw material pretreatment: Drying
    Requirements must be sufficiently dried, and the production requires the use of the drying hopper.
    Drying conditions: Normal air circulation oven drying hopper and equipment, more than 150 ℃ 5 hours.
    B.  the injection molding conditions

    Main points:
    a. PEEK molding process at high temperature, good thermal stability, degradation rate on temperature, shear rate and temperature insensitive to residence time. Therefore, it is desirable higher material temperature and high-speed injection, mold temperature control should be uniform in the process.
    b.PEEK is a crystalline plastic, thus improve its performance can make it sufficiently crystallized, the mold temperature is generally at least 160 ℃ to can make it sufficiently crystallized. Even without heat treatment , it can be well molded article. If the mold temperature is low or it require higher performance, it can be processed at more than 200 ℃ for 1 hour.
    c. mold and other considerations
    1. due to greater viscosity of PEEK, the nozzle, the gate and the runner should take a larger value, reduced pressure drop during flow.
    2. mold and equipment shall not have sharp corners, grooves, each corner should have smooth transition.
    3. mold runner and the cavity must use abrasion-resistant steels, and by good heat treatment, the cavity and the runner surfaces should be highly polished.
    4. mold design must have a good exhaust system.
    5. mold design and manufacturing must have sufficiently efficient heating systems and insulation systems to ensure that the mold may be heated to a temperature above 160 ℃.
    6. parts should be designed to avoid sharp corners, to arc transition.
