Title:
RESIN COMPOSITION, FLUORORESIN FILM USING SAME, AND FLUORORESIN METAL-CLAD LAMINATE
Document Type and Number:
WIPO Patent Application WO/2024/070495
Kind Code:
A1
Abstract:
Provided are: a resin composition capable of ensuring adhesion of a fluororesin, when employed in a substrate material in which the fluororesin is laminated on a metal substrate or the like, while enhancing the filling properties of an inorganic filler; a fluororesin film obtained by using said resin composition; and a fluororesin metal-clad laminate. The present invention provides a resin composition having a resin component (A) containing a fluororesin and an inorganic filler (B), wherein: the ratio of the component (A) relative to the sum of the components (A) and (B) is 20-50 mass% and the ratio of the component (B) relative to the sum is 50-80 mass%; the proportion of the fluororesin in the component (A) is 50 mass% or more; and regarding the component (B), the volume ratio of particles having a size of 3 μm or less is at least 10% and less than 30%, D50 indicating 50% of the volume-based cumulative distribution is 8-15 μm, and D90 is 30 μm or less. The present invention also provides a fluororesin film obtained by using said resin composition and a fluororesin metal-clad laminate.
