Anmei-TPU Flame Retardant for Engineering Plastics

TPU thermoplastic polyurethane elastomer is a type of polyurethane elastomer. It not only has the high elasticity of rubber but also has the plasticity of polymer materials.TPU (polyurethane) is flammable, and its limiting oxygen index (LOI) is about 18%. The flame-retardant TPU produced by Anmei has good tensile strength and abrasion resistance. 

TPU Flame Retardant Features

Main features：

Hardness 92 ShA

Density 1.25g/cc

Chemical resistance(hydrocarbon, petrol,oil and grease)

3.2mm Flammability Class: UL 94, V0

The color masterbatch uses TPU resin as the carrier, and the addition amount is1%~2%

In order to ensure the best performance index after extrusion, the material mustbe dried before processing, and the moisture content of the particles shouldnot exceed 0.02%.It is recommended that the material be dried at 80~110C for2~4h

It is suitable for cables that work at low temperature (-50~-70°C, relative humidity 95±3%)

TPU Flame Retardant Application

Flame retardant TPU is widely used in the field of 5G optical cables and cables, power cords, data cables and plugs in the electrical and electronic fields as well as in the automotive and new energy fields. It is essential for such a use that the polymers should have been flame-retarded, to help protect against ignition due to sparks and short-circuits. 

With the enhancement of environmental protection awareness, the electrical and electronic industries are fully halogen-free.

New Cable Sheath Material-TPU Flame Retardant Introduction

TPU has good flame-retardant technology and mechanical properties, making it a new type of cable halogen-free and low-smoke flame-retardant sheath material.

The flame-retardant TPU tensile strength is 20-50MPa, and the stress at break is 300-700%. Compared with other commonly used cable sheath materials like PVC or natural rubber or neoprene, it has wear resistance, oil resistance, high-energy radiation resistance, tear resistance, ozone resistance, low-temperature flexural resistance and other comprehensive properties are better.
