Abstract
A polyamide composition comprising: 100 parts by mass of polyamide (A) with a melting point of 270° C. to 340° C., 1 to 100 parts by mass of flame retardant (B), and 1 to 10 parts by mass of anti-dripping agent (C), wherein the anti-dripping agent (C) comprises a fluorine resin (C1) and at least one polymer (C2) selected from the group consisting of an ionomer and a modified aromatic vinyl-based polymer containing less than 15 mass % of halogen atom, in which a mass ratio of the fluorine resin (C1)/the polymer (C2) is 1/4 to 4/1.

A polyamide composition comprising:
- 100 parts by mass of polyamide (A) with a melting point of 270° C. to 340° C.,
- 1 to 100 parts by mass of flame retardant (B), and
- 1 to 10 parts by mass of anti-dripping agent (C),
- wherein the anti-dripping agent (C) comprises a fluorine resin (C1) and at least one polymer (C2) selected from the group consisting of an ionomer and a modified aromatic vinyl-based polymer containing less than 15 mass % of halogen atom, in which a mass ratio of the fluorine resin (C1)/the polymer (C2) is 1/4 to 4/1.
A method for manufacturing of a polyamide composition comprising:
- preparing an anti-dripping agent (C) comprising a fluorine resin (C1) and at least one polymer (C2) selected from the group consisting of an ionomer and a modified aromatic vinyl-based polymer containing less than 15 mass % of halogen atom, in which a mass ratio of the fluorine resin (C1)/the polymer (C2) is 1/4 to 4/1;
- and
- melt-kneading 100 parts by mass of polyamide (A) with a melting point of 270° C. to 340° C., 1 to 100 parts by mass of flame retardant (B), and 1 to 10 parts by mass of the anti-dripping agent (C).
