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