Polyvinyl chloride（PVC）Characteristic be proof voltage and insulaion resistance is higher, and there is fire-retardant, oil resistant, weathering, chemically-resistant
The performances such as product, but dielectric constant and dielectric loss are larger, and cold resistance is poor, but has low price, makes as general-purpose plastics
Consumption is big, all excellent characteristic of various aspects of performance, is mainly used in 1kV and following electric wire and local communication cable
The sheath of insulation, semi-conductive screen and various electric wire.TPUE have plastics repeat processability and
The characteristic of caoutchouc elasticity, in terms of cold resistance, wearability and antibiotic property, performance is excellent.TPUE be applied to from
Low-voltage to the cable jacket of 1KV, because it has unmatched hardness, low temperature flexibility, wearability, resistance to environment and weather-proof
Property, these characteristics all extend endurance and the service life of cable, and sharpest edges are environmental protection.By thermoplastic poly
Urethane elastomer and polychloroethylene blended, prepared urethane/polyvinyl chloride thermoplastic elastomer (TPE), can comprehensive polyurethane elastomer
With the advantage of polyvinyl chloride, the price of pure TPUE raw material can be reduced simultaneously.
《The preparation of PUR T/PVC thermoplastic elastomer (TPE) and technique are probed into》In one literary composition, preparation is extruded by melt blending
PUR T/PVC blending thermoplastic elastomer, when PUR T/PVC blending ratio is 70:30, plasticizer phthalic acid dioctyl ester is used
Measure as 20 parts, extrusion temperature is 160 DEG C, when screw speed is 330 r/min, the combination property of elastomeric material is optimal.
Although TPUE improves the toughness of pvc material, the mould of composite meanwhile also can be reduced
Amount, and employ dioctyl phthalate as plasticizer, its contained benzene ring structure has potential physiology to human body
Toxicity, and environmental pollution can be caused.So it is accomplished by substituting dioctyl phthalate using the plasticiser of environment-protecting asepsis, and
Add other additional properties that a series of altered contents improve composite, make the electricity more conforming to today's society demand
Cable, cable sheath material.
