Document Type and Number:
WIPO Patent Application WO/2024/058210
Kind Code:
A1
Abstract:
One embodiment of the present invention relates to a sliding composition film or a method for producing a sliding composition; the sliding composition contains an ethylene/α-olefin/non-conjugated polyene copolymer (A), a propylene random copolymer (B1) and a propylene homopolymer (B2) that each have a melt flow rate (MFR) of 0.1 to 4.0 g/10 min, a high density polyethylene (C1) that has a density of 940 to 970 kg/m3 and an MFR of 0.1 g/10 min or less, an ultra high molecular weight polyethylene (C2) that has a limiting viscosity (η) of 10 to 40 dl/g (at 135°C in decalin), an average particle diameter D50 of 22 to 50 µm and a density of less than 940 kg/m3, and a silicone compound (D) that has a kinematic viscosity of 3,000 to 1,000,000 cSt (at 25°C), respectively in specific amounts; and at least some of the copolymer (A) is crosslinked by a phenolic resin-based crosslinking agent.
