The invention relates to a TPE (
Thermoplastic Elastomer) material for a foamed floating cable extruded by a common extruder and a method. According to the technical scheme, the TPE material comprises at least one of ultra-high molecular weight SEBS and ultra-high molecular weight SEEPS, 10-100 parts of
long chain branch olefin polymers, 20-50 parts of
white oil, 20-160 parts of reinforced resins, 5-30 parts of
maleic anhydride grafted
polypropylene, 5-30 parts of nano-clay, 10-40 parts of aids, and 20-200 parts of a TPE base material foamed water master batch. The material has the beneficial effects that by utilizing the low
temperature sensitive and strain hardening phenomena of
long chain branch olefin polymers and the characteristics of low
melt viscosity and high melt strength of ultra-high molecular weight elastomers, the foamed melt has good foam structure stability at a certain temperature, the dependence on equipment and
processing parameters is reduced, the
product processing stability is improved, and the production cost is reduced; and moreover, foaming
extrusion of the common extruder can be realized, the
foaming agent is uniformly dispersed, the foaming process is stable, foam is uniform and dense, and the foamed product is fine, smooth and soft in surface, high in strength and high in
weather resistance.
