Abstract
The polyamide resin composition of the present invention comprises: about 15 to about 49 wt % of an aromatic polyamide resin containing a repeating unit represented by chemical formula 1 and a repeating unit represented by chemical formula 2; about 1 to about 30 wt % of a polyamide resin having a glass transition temperature of about 40 to about 120° C.; about 1 to about 20 wt % of an olefin-based copolymer; about 5 to about 40 wt % of calcium carbonate; and about 5 to about 40 wt % of talc. The polyamide resin composition and the molded product formed therefrom are excellent in plating adhesion, impact resistance, stiffness, heat resistance, flowability, appearance characteristics, and the like.
Claims14
A polyamide resin composition comprising:
- about 15 wt % to about 49 wt % of an aromatic polyamide resin comprising a repeat unit represented by Formula 1 and a repeat unit represented by Formula 2;
- about 1 wt % to about 30 wt % of a polyamide resin having a glass transition temperature of about 40° C. to about 120° C.;
- about 1 wt % to about 20 wt % of an olefin copolymer;
- about 5 wt % to about 40 wt % of calcium carbonate;
- and
- about 5 wt % to about 40 wt % of talc,
- wherein the aromatic polyamide resin and the polyamide resin having a glass transition temperature of about 40° C. to about 120° C. are present in a weight ratio of about 4:1 to about 10:1, and
- wherein the calcium carbonate and the talc are present in a weight ratio of about 1:0.5 to about 1:4,
- where R1 and R3 are each independently a C1 to C6 hydrocarbon group or a halogen atom, R2 and R4 are each independently a C6 to C12 linear or branched alkylene group, and n1 and n2 are each independently an integer of 0 to 4.
