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.
