The resin composition contains a polyamide resin and cerium oxide, with a lanthanum content in the resin composition of more than 0 ppm by mass and 40 ppm by mass or less.

Resin composition, molded article, and method for producing resin composition

To provide a resin composition that contains a glass fiber, but having reduced warpage of a formed article and high transmittance; as well as a formed article, a kit, and a method for manufacturing a formed article using the same. The polyamide resin composition contains a polyamide resin, a glass fiber, a light-transmitting dye, and muscovite.

Resin composition, formed article, kit, and method for manufacturing formed article

To provide a resin composition having large light transmittance and capable of providing a molded article which is highly laser-weldable to an absorbing resin member, as well as a kit, a method for manufacturing the resin composition, a method for manufacturing a formed article, and a formed article. The resin composition contains a polyamide resin, a maleic anhydride-modified polyphenylene ether-based resin, a phosphazene-based flame retardant, a zinc metal oxide, and a light transmitting dye.

Resin composition, kit, method for manufacturing resin composition, method for manufacturing formed article, and formed article

To provide a polyamide resin composition that contains a halogen-containing flame retardant, which excels in flame retardance, well suppressed from degrading the transmittance due to darkening, and such molded article. The polyamide resin composition contains a polyamide resin, 1 to 10% by mass of a halogen-containing flame retardant, and 1 to 5% by mass of antimony oxide, the polyamide resin composition having a phosphorus atom concentration of 1.50&#xd7;10% by mass or less.

Polyamide resin composition and molded article

Provided is a molded article which contains a first enclosure; a second enclosure adjoined with the first enclosure; and a transparent member held by the second enclosure, each of the first enclosure and the second enclosure being independently made from a resin composition that contains a polyamide resin having a semi-crystallization time of 10 to 60 seconds, and a melting point of 200 to 280&#xb0; C., and the transparent member having a pencil hardness of 8H or larger, and a linear expansion coefficient of 1&#xd7;10to 9&#xd7;10/&#xb0; C., where the semi-crystallization time means a time measured by depolarization photometry at a temperature 20&#xb0; C. higher than the melting point of the polyamide resin, for a melting time of polyamide resin of 5 minutes, and at a temperature of crystallization bath of 150&#xb0; C.

Molded article and method for manufacturing molded article

Provided is a polyamide resin composition that has a large light transmittance with respect to 940 nm laser beam, and is capable of yielding a molded article that is highly laser weldable; and a kit, a method for manufacturing a molded article, and a molded article, using such polyamide resin composition.
