Title:
DISPERSION COMPOSITION, FLUORORESIN FILM, METAL-CLAD LAMINATED BOARD, AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2023/189795
Kind Code:
A1
Abstract:
The present invention contains (A) fluororesin powder and (B) an inorganic filler and further contains one of or both of: (X) one or more oligomers selected from the group consisting of aliphatic or semi-aromatic hydrocarbon-based oligomers, acrylic oligomers, urethane-based oligomers, imide-based oligomers, ester-based oligomers, and amide-based oligomers; and (Y) a resin that exhibits a storage elastic modulus of 1800 MPa or less at 50°C when formed into a film, wherein the maximum value of the storage elastic modulus in the temperature range of 180°C-260°C is 800 MPa or less. The total amount of the component (X) and the component (Y) is 3.5 parts by weight or more based on 100 parts by weight of the total amount of the component (A) and the component (B).
