Polyarylate resin

U polymer

AX series (Opaque chemical-resistant grade)

AX series resins are opaque polymer alloys with a high deflection temperature under load without reinforcement and a chemical resistance as high as those of crystalline resins. They are excellent in moldability and provide molded products fewer in the number of sink marks, warps, and run-offs.

Characteristics

  1. Nonreinforced heat resistance:
    Deflection temperature under load without reinforcement: 1.8 MPa at 150°C
  2. Chemical resistance:
    As high as those of polyamide resins, except alkali resistance
  3. Adhesiveness:
    Chemical resistance and adhesiveness as high as those of crystalline resins
  4. Lubrication:
    As high as those of polyamide resins
  5. Molding accuracy:
    Fewer in the number of sink marks and warps, and lower (less than 1/3) in water absorption than polyamide resins
