Description
ThermoLyn PETG clear 616T183 is a highly transparent PETG sheet for prosthetic fabrication, particularly well suited as the first layer in definitive sockets. It is designed for prosthetics workshops looking to create a clean, stable and reproducible foundation for above-knee prostheses, with or without a liner. Thanks to its smooth inner surface and shatterproof construction, ThermoLyn PETG clear 616T183 supports precise processing in everyday workshop use.
As a copolyester, ThermoLyn PETG clear 616T183 is typically used as the first layer in definitive sockets, for example in Harmony fittings. Its high transparency makes visual inspection during fabrication easier and helps achieve a clean result. At the same time, the material is shatterproof and impact-resistant—ideal when durable components are needed for everyday use. With low shrinkage of approx. 1%, ThermoLyn PETG clear 616T183 can be processed reliably, helping to ensure a consistent fit.
Practical workflow benefits: the plaster does not need to dry after the test socket has been transferred. Even damp plaster does not need to be isolated before lamination—saving time and simplifying preparation. PETG can also replace the inner film, reducing material changes while providing a very smooth inner surface. ThermoLyn PETG clear 616T183 is suitable for liner fittings with or without a distal connection, supporting different fitting strategies for above-knee prostheses.
