<p>Material for moulding shoe soles comprises (a) 100 pts. wt 1,2-polybutadiene, (b) 5-90 pts. wt. of a diene rubber (e.g. polyisoprene) and (c) (per 100 pts. wt. 1,2-polybutadiene and diene rubber) 30-120 pts. rubber processing additives. The diene rubber component may be e.g. natural rubber SBR polybutadiene rubber and/or polyisoprene rubber. The rubber compsns. have good injection moulding props. and the shoe soles produced have the desired physical characteristics. e.g. tensile strength >=75 kg/cm2, elongation >=300%, good wear resistance (abrasion resistance) high resistance to flex cracking etc.</p> |
