Polycarbonate Diols to produce extremely durable PU

Polycarbonate Diols (PCD) are used for a wide range of polyurethane-based material formulations, providing an extreme durability and a high performance to the final polymer.

These products offer customizable possibilities for superior & long-term retention of designed performances, with no modification of initial properties after being exposed in harsh environments.

The Polyurethane produced from PCD is superior to the one
produced from polyether-diol or polyester-diol in terms of durability.

Why? Because it can provide outstanding performances, such as:
  • Excellent hydrolytic stability
  • Increased chemical and stain resistance
  • High thermal stability / lower yellowish
  • Improved mechanical properties
  • Better retention of gloss
  • Very good scratch & abrasion resistance, and others!

Case Studies from Polycarbonate Diols for durable PU Center

Improve the performance & endurance of PU based elastomer rollers

Elastomer rollers can be used to protect, squeeze, feed, insulate or convey products. For this, TPU covered rollers have always offered many advantages. 

They are now significantly upgraded with new Polycarbonate diol-based TPUs, integrating the Eternacoll® Polycarbonate diol technology: they are very resistant to friction & heat, as well as solvents and hydrolysis.
