Title:
POLYOLEFIN FOAM SHEET AND PRESSURE-SENSITIVE ADHESIVE TAPE
Document Type and Number:
WIPO Patent Application WO/2015/152222
Kind Code:
A1
Abstract:
This polyolefin foam sheet is obtained by foaming a resin composition containing a polyolefin resin (A) and a styrene thermoplastic elastomer (B) for which the temperature that maximizes the peak value of tan δ, as per dynamic-viscoelasticity measurement, is between −30°C and 10°C, inclusive. The ratio (A/B) of the mass of the polyolefin resin (A) to the mass of the styrene thermoplastic elastomer (B) is between 50:50 and 90:10, inclusive, and the thickness of the polyolefin foam sheet is between 0.05 and 1.0 mm, inclusive.
