The present application discloses a method for making a rubber blade. The method includes applying a first coating composition and a second coating composition in separate steps on at least a part of a surface of a polyurethane elastic substrate; and solidifying the first coating composition and the second coating composition by ultraviolet light irradiating to form a hardened layer on the surface of the polyurethane elastic substrate. The first coating composition includes an isocyanate-group-terminated polyisocyanate and a first solvent. The second coating composition includes a first monomer, a photoinitiator, and a second solvent. The first monomer is at least one of an acrylate monomer and a methacrylate monomer each having an reactive hydroxyl group. The isocyanate group of the polyisocyanate is reacted with the reactive hydroxyl group of the first monomer to generate a urethane group to form a polyurethane acrylate. The present application also discloses a rubber blade.

A thermoplastic polyurethane elastomer material with micro air holes and preparation thereof are provided. The formula of the thermoplastic polyurethane elastomer material with micro air holes comprises the following ingredients in percentage by weight: 0.1-97% of support polymer material, 0.1-97% of pressure-resistant slow-rebound polymer material, 0.01-0.5% of nucleator and 0.1-10% of foaming agent. The support polymer material is a polymer material with a high molecular weight, high hardness, high crystallization or high polarity. The pressure-resistant slow-rebound polymer material is a polymer material with a low molecular weight, low hardness, crystallization as low as to amorphous state or low polarity/no polarity, corresponding to the support polymer material.

An article has a density of from 0.03 to 0.45 g/cc. The article includes a plurality of anisotropic tubular particles that are randomly oriented in the article. The tubular particles include a thermoplastic elastomer foam and a non-foamed polymer disposed on an exterior surface of the thermoplastic elastomer foam as an outermost layer of the tubular particles. Each of the thermoplastic elastomer foam and the non-foamed polymer independently has a softening temperature determined according to DIN ISO 306. Moreover, the non-foamed polymer includes an additive that is responsive to non-heat energy to selectively heat the non-foamed polymer to its softening temperature prior to the thermoplastic elastomer foam reaching its softening temperature.
