Title:

NET-SHAPED OBJECT WITH EXCELLENT HIGH-TEMPERATURE DURABILITY

Document Type and Number:

WIPO Patent Application WO/2016/093334

Kind Code:

A1

Abstract:

The purpose of the present invention is to provide a net-shaped object which, although being obtained using a polyolefin-based thermoplastic elastomer, has a given hardness, has a reduced compressive residual set even at a high temperature and a high humidity, and is suitable for use in applications such as cushions. The net-shaped object has a three-dimensional, randomly loop-bonded structure configured of continuous filaments of a polyolefin-based thermoplastic elastomer comprising an olefin block copolymer, the filaments having a fiber diameter of 0.1-3.0 mm. The net-shaped object has an apparent density of 0.005-0.20 g/cm3 and a compressive residual set measured at 70°C of 30% or less.
