Abstract
Disclosed are plastic compositions for use in forming plastic-metal hybrid materials, the compositions including an epoxy compound. Also provided are plastic-metal hybrid materials that are formed using the inventive plastic compositions, methods for forming such materials, and electronic devices that include the hybrid materials. The plastic compositions confer beneficial bonding strength with the metal partner of a hybrid material, good impact strength, and low color change following anodization, and retain these favorable characteristics under a range of processing conditions.
Claims14
A plastic composition for use in forming a plastic-metal hybrid material comprising:
- about 45-65% by weight polybutylene terephthalate;
- about 6-13% by weight of an epoxy compound;
- 0 to about 10% by weight of an impact modifier;
- about 25-45% by weight of glass fibers;
- and
- 0 to about 1% by weight of polyethylene,
- wherein the epoxy compound has an epoxide equivalent weight of less than 550 g/eq as measured according to ASTM D-1652,
- wherein the plastic composition does not include polyethylene terephthalate, and
- wherein the total percentage by weight of all components is 100.
