MoldingPROPERTY

  • High impact resistance

    The impact resistance of SUNFINE™-molded products is superior to products molded from other engineering plastics.
    It is also notable that they retain their high impact resistance even at -40 °C.

    High impact resistance (-40℃)

  • High wear resistance

    High wear resistance

    The wear resistance of SUNFINE™-molded products is superior to products molded from other engineering plastics.

  • Very low metal residues and
    low contamination

    SUNFINE™ is produced under strict plant management conditions that ensure the cleanliness of plants to maintain the high quality of raw materials.

    SUNFINE™ is manufactured only in Japan to ensure that strict plant management is implemented to maintain its high quality.

    High quality stability

    Strict manufacturing operations and advanced catalyst technology produce very little variation in physical properties between lots. This makes a major contribution to the production stability of Asahi Kasei's customers.

 

MoldingFIELD OF USE

  • Impact Resistance

    Impact Resistance

    SUNFINE™ exhibits greater impact resistance than other engineering plastic materials and competitive UHMWPEs.

  • Wear Resistance

    Wear Resistance

    With very low friction on steel materials, SUNFINE™ has higher wear resistance than other engineering plastic materials and competitive UHMWPEs. Its high wear resistance prevents the wearing of materials that it contacts.

  • Sliding Properties

    Sliding Properties

    The impressive sliding properties of SUNFINE™ prevent scratches on product surfaces. This results in a reduction of the noises from conveyance and other processes.

  • Hygiene

    Hygiene

    Some grades conform to the Specifications and Standards for Food, Food Additives, etc. (Public Notice of the Japanese Ministry of Health and Welfare No. 370 of 1959, in the category of use at a temperature of 100 °C or below).

  • Chemical resistance

    Chemical resistance

    SUNFINE™ has excellent corrosion resistance to various chemicals. No deterioration is observed in the physical properties of SUNFINE™  when exposed to most acids, alkalis and organic solvents.

  • Lightweight

    Lightweight

    SUNFINE™ has a specific gravity from 0.92 to 0.94. It is one of the most lightweight engineering plastics.

MoldingCASE

  • Low coefficient of friction
    and high wear-resistance

    SUNFINE™ is used in many different applications including linings for silos, hoppers, and other equipment, mechanical parts such as gears and gaskets, blades for farming machines and implements, as well as bulldozers and other machine tool components.  We are ready to provide an array of grades to respond to market needs.
