Desmopan® CQ 9385D MBC 091
What is it?
A thermoplastic polyurethane (TPU) with a reduced carbon footprint. The ISCC Plus-certified mass-balance solution with a sustainable share of approximately 36% results in improved sustainability. Within the family of thermoplastic elastomers (TPE), TPU is a typical choice because of its especially good wear and thermal resistance, and this grade represents the Polyether-Polyurethane branch of the TPU family.
Desmopan® CQ is a group of partly bio-based TPU grades ranging across a wide spectrum of hardnesses from hard and stiff to soft and elastic, for extrusion and injection moulding.

Tensile Modulus D (MPa): 2020
Flexural Modulus (MPa): 2,166
Flexural Stress (MPa): 90
Flexural Stress at 5% Strain (MPa): 89
Izod Notched Impact Strength, +23°C (kJ/m2): 64.1
Shore Hardness: 79D

This grade is characterized by a broad service temperature area. Its heat resistance is good, but its flexibility is also well preserved in cold conditions. This material offers high resistance against stress cracking and good resistance against microbes and hydrolysis.
Look and feel
Though a TPU, the look and feel of this grade is closer to what we normally experience with rigid engineering polymers, such as PBT or ABS. The surface has a high gloss and is practically free of sink marks. By bending and knocking the sample, one can sense the high ductility of the material.
According to an LCA analysis, the CO2 reduction compared with the fossil-based version is about 30%.
This material is suitable for flexible technical parts with high-temperature requirements, including shoe soles, technical housings, or structural parts requiring good chemical resistance. It’s also used in extruded film and sheets.
Why we chose this material
TPU is a widely used and highly specialized material. We are happy to see a new option with superior properties that also offers a reduced carbon footprint. We are also curious to study what kind of alternative TPU with a high Shore D value offers to hard thermoplastics.
Why you should consider this material
You need a ductile material for an application with a wide service temperature area.
You value a material choice with a reduced environmental footprint.
Your are looking for a material that can be in contact with water.
