Foamed TPU Material

TPU Cable Compound: Foamed Thermoplastic Polyurethane

Product features:

1.Lightweight and low density (below 0.4-0.8g/cm³)

2.Cracking resistance and high tensile strength

3.Acid and alkali resistance, corrosion resistance

4.Excellent oil resistance

5.Excellent elasticity and soft appearance

6.Good hydrolysis resistance

7.Good wear resistance and heat resistance

8.The surface of the foamed cable is dense, the internal pores are uniform, and the foaming rate is high

Application areas:

Commonly used in the manufacture of new energy charging pile wires and cables, plug materials, wire outer sheaths, medical cables, and marine floating cables.

Foamed TPU cable material is a cable material that uses thermoplastic polyurethane (TPU) as a base material and is foamed by adding a foaming agent. This material is increasingly used in the wire and cable industry due to its unique properties.

Characteristics

Light weight: The density of foamed TPU can be controlled at 0.70-0.80 g/cm³, which enables the cable to float on the water surface and is suitable for marine and water applications.

High flexibility: Foamed TPU cable materials maintain the flexibility of TPU and are easy to install and deploy.

Good wear resistance and tensile strength: Foamed TPU cable materials inherit the wear resistance and high tensile strength of TPU and are suitable for harsh environments.

Thermal insulation performance: The pore structure of foamed TPU provides good thermal insulation and is suitable for cables that require heat preservation or insulation.

Environmental protection: TPU materials can be recycled, and foamed TPU cable materials meet environmental protection requirements.

Preparation Method

Raw material preparation: TPU and compatibilizer are dried to remove moisture.

Mixing: Add TPU, foaming agent, antioxidant, PP (polypropylene), compatibilizer and anti-hydrolysis agent into the mixer in a certain proportion and mix at high speed.

Extrusion granulation: Extrusion granulation of the mixed raw materials through an extruder to form a foamed TPU composition.
