Elastollan
Elastollan is a series of thermoplastic polyurethane (TPU) products manufactured by BASF. TPUs are known for their exceptional mechanical properties, including high elasticity, abrasion resistance, and chemical resistance. Elastollan products are available in a wide range of hardness and viscosity options to meet different application requirements.

Formulation and Characterization of TPU
Characterizing TPU Elastollan Material Properties
The TPU material was supplied already granulated, with the granules having the shape of an elongated spheroid. The typical size of a single granule is approximately 4.95 mm about the long axis and 3 mm about the shorter axis, and it weighs 0.03 g. The material was always stored in its original resealed package bag in a dry room. Other physical properties of the two materials can be found online on the manufacturer’s websites [49 ], but some relevant values are also presented here in
Polymer Substrate Fabrication Protocol
A heating press from VOGT Maschinenbau GmbH (Berlin, Germany) was used to produce flat samples. The temperature control to the target value for the upper and lower plates was carried out separately. The pressing process of the pre-dried granulate was carried out with the aid of intermediate layers of Polytetrafluorethylene-coated glass fabric Type 7069 from TACONIC (Rensselaer, NY, USA). Spacers between the glass fabrics were used to achieve a defined layer thickness of the flat samples. The processing temperature for the respective polymer is shown in
After the press plates had reached the spacers, a residence time of 30 s was observed to ensure complete melting of the polymer. The intermediate layers were then removed and cooled in a water bath. After cooling, the sample could be removed easily from the intermediate layers.
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
