Abstract
Official abstract text for this publication.
The present invention aims to provide a film having excellent mechanical strength and abrasion resistance. The film of the present invention contains an aromatic polyether ketone resin (I) and a fluororesin (II). The aromatic polyether ketone resin (I) has a crystallinity of 10% or higher.
First claim
Opening claim text (preview).
The invention claimed is: 1. A film comprising: an aromatic polyether ketone resin (I); and a fluororesin (II), the aromatic polyether ketone resin (I) having a crystallinity of 15% or higher. 2. The film according to claim 1 , wherein the fluororesin (II) is a copolymer of tetrafluoroethylene and a perfluoroethylenic unsaturated compound represented by the following formula (1): CF 2 ═CF—Rf 1 (1) wherein Rf 1 is —CF 3 or —ORf 2 ; and Rf 2 is a C1-C5 perfluoroalkyl group. 3. The film according to claim 1 , wherein the aromatic polyether ketone resin (I) and the fluororesin (II) have a mass ratio (I):(II) of 40:60 to 99:1. 4. The film according to claim 1 , wherein the fluororesin (II) is dispersed as particles in the aromatic polyether ketone resin (I). 5. The film according to claim 4 , wherein the fluororesin (II) has an average dispersed particle size of 3.0 μm or smaller in the aromatic polyether ketone resin (I). 6. The film according to claim 1 , wherein the aromatic polyether ketone resin (I) and the fluororesin (II) have a melt viscosity ratio (I)/(II) of 0.01 to 5.0. 7. The film according to claim 1 , wherein the fluororesin (II) has a melt flow rate of 0.1 to 100 g/10 min. 8. The film according to claim 1 , wherein the aromatic polyether ketone resin (I) is polyether ether ketone. 9. A diaphragm for speakers, comprising the film according to claim 1 . 10. A thrust washer comprising the film according to claim 1 .
