Abstract
A pellet including a liquid crystal polyester and a fibrous filler (A), in which a ratio (N1/C1) of the number of spots per unit area N1 (/mm2), which are derived from the fibrous filler (A) and observed in a cross section perpendicular, to the extrusion direction of the pellet to a content rate C1 of the fibrous filler (A) is 3,500 or more and 20,000 or less.
Claims7
A pellet comprising a liquid crystal polyester and a fibrous filler (A),
- wherein a ratio (N1/C1) of the number of spots per unit area N1 (/mm2), which are derived from the fibrous filler (A) and observed in a cross section perpendicular to the extrusion direction of the pellet, to a content rate C1 of the fibrous filler (A) is 3,500 or more and 20,000 or less.
A method for producing a pellet, comprising a step of melt-kneading a liquid crystal polyester and a fibrous filler and forming the mixture to obtain a pellet,
- wherein the step is a step of carrying out the melt-kneading and forming so that a ratio (N1/C1) of the number of spots per unit area N1 (/mm2), which are derived from the fibrous filler (A) and observed in a cross section perpendicular to the extrusion direction of the pellet, to a content rate C1 of the fibrous filler (A) in the pellet is 3,500 or more and 20,000 or less.
