TPU – Thermoplastic Polyurethane

**Thermoplastic Polyurethanes (TPU)** are technically thermoplastic elastomers consisting of linear segmented block copolymers composed of hard and soft segments. TPU is a block copolymer consisting of alternating sequences of hard and soft segments or domains formed by the reaction of di-isocyanates with short-chain diols (chain extenders) and di-isocyanates with long-chain diols. By varying the ratio, structure, and/or molecular weight of the reaction compounds, a wide variety of TPU can be produced, allowing chemists to fine-tune the polymer's structure to the desired final properties.

NPPL TPU industry portfolio range :

  1. Automobile Industry
  2. Consumer Electronics
  3. Consumer Footwear
  1. Engineering Polymers
  2. Wire & Cables
  3. Medical applications & many others

TPU materials are characterized primarily by their high mechanical strength, very good abrasion resistance and show good resistance to various non-polar chemicals. In contrast, the is material damage from contact with water or aqueous material and is therefore essential to dry TPU compounds before processing. This also supports the process ability of the materials.

The materials can be colored, and some manufacturers also offer translucent TPU. Customized properties include :

  1. Abrasion resistance
  2. Mechanical strength
  3. Low temperature flexibility
  1. Heat aging
  2. Resistance to various non-polar chemicals
  3. Injectability
