Abstract: A polymer composite contains tubular particles, which contain at least one resin with fibres embedded. The tubular particles have an average length in the range of 0.5 mm to 60 mm and an average wall thickness in the range of 0.0005 mm to 30 mm, whereas the fibers have an average diameter in the range of 0.0005 mm to 5.0 mm. A process can be used to prepare the polymer composite containing tubular particles. The polymer composite can be used as a cushioning material, which can be formed into a cushioning article such as a shoe sole, a furniture cushion, a bed mattress, an automotive seat cushion, a flooring substrate, an outdoor/walking surface, a mat, a pad, and the like.

Abstract: 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.
