The characteristic of caoutchouc elasticity, shows excellent in terms of tolerance to cold, wearability and antibiotic property.Polyurethane Thermoplastic Elastomer be applied to from
Low-voltage is to the cable jacket of 1KV, because it has unmatched hardness, and 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, with polychloroethylene blended, prepares urethane/polyvinyl chloride thermoplastic elastomer (TPE), can comprehensive polyurethane elastomer
With the advantage of polrvinyl chloride, the price of pure Polyurethane Thermoplastic Elastomer raw material can be reduced simultaneously.
By melt blending extrusion preparation in " preparation and the technique of PUR T/PVC thermoplastic elastomer (TPE) are probed into " literary composition
PUR T/PVC blending thermoplastic elastomer, when PUR T/PVC blending ratio is 70:30, plasticizer phthalic acid dioctyl ester is used
Amount is 20 parts, and extrusion temperature is 160 DEG C, and when screw speed is 330 r/min, the combination property of elastomeric material is optimal.
Although Polyurethane Thermoplastic Elastomer improves the toughness of pvc material, the mould of composite the most also can be reduced
Amount, and have employed dioctyl phthalate as plasticizer, its contained benzene ring structure has potential physiology to human body
Toxicity, and environmental pollution can be caused.The plasticiser utilizing environment-protecting asepsis is thus needed to substitute dioctyl phthalate, and
Add a series of altered contents and improve other additional properties of composite, make the electricity more conforming to society demand
Cable, cable sheath material.
