摘要： A resin tube is a tube that is composed of a first fluoropolymer and a second fluoropolymer. The first fluoropolymer is made of a melt-type fluoropolymer that melts at a temperature higher than a melting point, and the second fluoropolymer is made of polytetrafluoroethylene or a cross-linked fluoropolymer. An inner circumferential surface of the tube has irregularities with arithmetic average roughness Ra of 1 μm or more.

摘要： Embossing resins, methods of manufacturing such resins, and electrokinetic display system, which includes display cells containing such resins. The resins include a fluoropolymer in weight percentage 5%-60%, a difunctional diluent in weight percentage 0-30%, a monofunctional diluent in weight percentage 0-40%, a urethane diacrylate or functionalized nanoscale material, e.g., a functionalized urethane material, in weight percentage 5-50%, a photoinitiator in weight percentage 0.5-5%, and a surfactant in weight percentage less than 0.5%. The difunctional diluent may be Hexanediol Diacrylate, and the monofunctional diluent may be a monofunctional hydrocarbon. The resins are made by identifying a target index of refraction for a cured state thereof, and combining together, by weight percentage, the constituent components to produce the liquid state version of the embossing resin having a desired composite index of refraction.
