ABSTRACT:
Thermoplastic elastomeric compositions are prepared by mixing comminuted vulcanized rubber having a mean particle size of below 1.5 mm with a thermoplastic olefin or diolefin polymer, particular polyethylene, at a weight ratio of from 1:3 to 3:1, and with a non-ionic surfactant in an amount of 0.1 to 5 wt. % referring to the total amount of polymers. The addition of a non-ionic surfactant greatly improves the bonding between the two main components, thus yielding compositions of a very low level of porosity and improved mechanical properties, particularly superior thoughness.
The compositions can be moulded or extruded to a variety of products, such as profiles, roofings, fencing posts, pallets, and also shoe sales, saddle covers, solid tires, sprinkling funnels, etc.
