Abstract
Official abstract text for this publication.
A resin composition and a molded article. The resin composition contains a fluororesin and boron nitride particles, the fluororesin being present in an amount of 35 to 70% by mass and the boron nitride particles being present in an amount of 30 to 65% by mass, each relative to the resin composition, the resin composition having a melt flow rate of 5.0 g/10 min or more.
First claim
Opening claim text (preview).
The invention claimed is: 1. A resin composition comprising a fluororesin and boron nitride particles, the fluororesin being present in an amount of 35 to 70% by mass and the boron nitride particles being present in an amount of 30 to 65% by mass, each relative to the resin composition, the resin composition having a melt flow rate of 5.0 g/10 min or more, wherein the boron nitride particles have a 90% particle size (D90) of 5.0 μm to 9.0 μm. 2. The resin composition according to claim 1 , wherein the boron nitride particles have a ratio of a proportion (b) of particles having a particle size of 24.6 to 29.4 μm to a proportion (a) of particles having a particle size of 14.6 to 20.6 μm ((b)/(a)) of 1.0 or higher. 3. The resin composition according to claim 1 , wherein the boron nitride particles include particles having a particle size of 14.6 to 20.6 μm in a proportion (a) of 5.0% or less. 4. The resin composition according to claim 1 , wherein the boron nitride particles include particles having a particle size of 24.6 to 29.4 μm in a proportion (b) of 10.0% or less. 5. The resin composition according to claim 1 , wherein the fluororesin is a melt-fabricable fluororesin. 6. The resin composition according to claim 1 , wherein the fluororesin includes at least one selected from the group consisting of a tetrafluoroethylene/perfluoro(alkyl vinyl ether) copolymer, a tetrafluoroethylene/hexafluoropropylene copolymer, and an ethylene/tetrafluoroethylene copolymer. 7. The resin composition according to claim 1 , wherein the resin composition has a thermal conductivity of 1.5 W/m·K or higher. 8. The resin composition according to claim 1 , wherein the resin composition has a tensile strain at break of 1.0% or higher. 9. A molded article obtained by injection molding the resin composition according to claim 1 .
