Formulate extremely durable Polyurethane elastomers

Formulating the right Polyurethane elastomers that can resist to extreme environmental conditions such as high and low temperatures, humidity, stain and chemical aggressions while ensuring durable high performance is a challenge.

Polycarbonate Diols (PCD) offer customizable possibilities with superior and long-term retention of designed performances, without modification of initial properties after being exposed in harsh environments.

The outstanding durability of Polyurethane elastomers based on PCS is obtained thanks to different performances, such as:

Excellent water resistance of Polyurethane elastomers

Polycarbonate Diols (PCD) allow formulators to provide extremely durable Polyurethane elastomers thanks to increased resistance to water / hydrolysis.

Figure 1 shows that water absorption is less important (-52%) for Polyurethane elastomers based on PCD.
This leads to minor weight increment and better resistance to hydrolysis than Polyurethane based on benchmark Diols.

Therefore, Polyurethane elastomers formulated with Eternacoll® withstand extreme humid conditions and remain intact after long-term exposure to water and humidity.

Increased chemical & stain resistance of Polyurethane elastomers

Exposure to harsh solvents and fluids tends to damage materials over time, causing them to fade, discolor and get stained.
Polycarbonate Diols (PCD) can help you to overcome this annoying constraint by enhancing the chemical and stain resistance of your Polyurethane elastomers.

ArrowChemical resistance

An ethanol resistance test was run in order to compare the chemical resistance of Diol-based Polyurethanes (see picture 1).
As illustrated on Figure 2, Polyurethane formulated with Eternacoll® PCD shows an improved resistance to harsh solvents compared to Polyurethane based on benchmark Diols.

The use of Eternacoll® PCD in your Polyurethane formulations allows you to provide highly durable Polyurethane elastomers that can better resist to exposure of chemicals.

This makes Eternacoll® PCD suitable for applications in which Polyurethane elastomers have to resist to very harsh environmental conditions, such as oil & mining pipes inner cast.

Arrow Stain resistance

Last but not least, Polycarbonate Diols also have the advantage of providing an outstanding stain resistance to Polyurethane-based materials.

High thermal stability of Polyurethane elastomers

If temperature resistance is a must-have for your Polyurethane elastomers and if you can’t afford to provide Polyurethane that tends to yellowish over time, then PCD is the technology you have always been looking for!

Polycarbonate Diols provide a very high thermal stability to Polyurethane elastomers compared to traditional Polyester and Polyether Diols, thanks to excellent heat resistance.

Figure 3 illustrates that Eternacoll® PCD has a very low increment of yellowness index after artificial weathering compared to standard Polyether and Polyester Diols.

Improved mechanical properties of Polyurethane elastomers

Formulating Polyurethane with Polycarbonate Diols (PCD) maximizes the performance of elastomer formulations. How?

Polyurethane based on Eternacoll® PCD shows better mechanical properties compared to Polyurethane based on traditional Diols:
  • The Polyurethane elastomer has a better tensile strength (+329%) and is therefore less elastic (Figure 5)
  • It also shows a better hardness (+173%), as illustrated on Figure 6

Hardness of Diol-based PU

The improvement of mechanical properties allows you to provide a Polyurethane which is less elastic and shows a better hardness, for highly durable materials!

Increased scratch & abrasion resistance of Polyurethane elastomers

Polyurethane elastomers formulated with Polycarbonate Diols show increased abrasion and scratch resistance, and are therefore more durable than the ones formulated with standard Diols.

ArrowAbrasion resistance

Figure 7 shows that Polyurethane based on Eternacoll® Polycarbonate Diols loses less volume when exposed to harsh conditions than Polyurethane based on traditional Diols, and has therefore a better resistance to abrasion:

ArrowScratch resistance

Scratch resistance of PCD-based Polyurethane has been tested thanks to the determination of film hardness with pencil test.
Figure 8 illustrates that Polyurethane elastomers based on Eternacoll® PCD have a higher hardness and therefore an increased scratch resistance than benchmark Diols.
