Enhance abrasion resistance & flexibility of your PVC compounds thanks to TPU

Market: Wires & Hoses, Coatings, Artificial Leather, Footwear  Polymer: Specialty Thermoplastic Polyurethane (TPU)  Key performance: Improved Compatibility with PVC Enhanced low Temperature Flexibility High Mechanical Properties and Wear Resistance Transparency

When it comes to PVC compounds, either for automotive or industrial applications, additives are required in order to improve impact modification resistance and flexibility at low temperature.

Today, a TPU alternative specifically developed for PVC compatibility does exist to overcome most challenges.

Indeed, Pearlcoat® DIPP 119 has shown the following benefits over traditional solutions:

       Low Melting Range for easy blending (120-130°C) and reduced PVC degradation

       Soft∗ for comfort and a wider range of applications (70 Sh A)

       Copolyester Polycaprolactone backbone for improved compatibility.

Used as additives, Thermoplastic Polyurethanes (TPUs) make PVC parts tougher, more flexible at low temperatures, as well as more abrasion resistant, as can be seen in the charts below:

Graph 1: Brittleness enhancement of PVC / TPU blend

Graph 2: Abrasion loss improvement thanks to TPU in PVC

While many TPUs in the market may be said to be compatible with soft PVC, they are often hard to blend with PVC, due to standard ester chemistry with limited chemical affinity as well as higher melting point and hardness (75-85 Sh A).

Pearlcoat® DIPP 119 shows a higher quality compound benefit over traditional solutions.

For applications which need to use clear PVC, Pearlcoat® DIPP 119 allows to preserve transparency.
