At Intercarat, moulded parts made of PTFE and modified PTFE (TFM™) are press moulded and sintered.
Due to its excellent resistance to numerous chemicals, polytetrafluoroethylene (PTFE) is primarily used in the chemical industry as well as in the microelectronics and semiconductor industries. This material is also used for processes in other industrial sectors, for example for the dosing and flushing of process plants with cleaning agents in the pharmaceutical industry, and in the production of foodstuffs. In addition to standard PTFE, a second-generation PTFE is now also available. This type (brand name TFM™) boasts, for example, a much higher dynamic strength and an optimised setting behaviour.
At Intercarat, thermoplastic materials are compressed on hydrodynamic 5-axis presses pulverulently at room temperature in a cleanroom based on class 9. This involves compressing and compacting the loose bulk powder. After press moulding, the moulded parts are subjected to a defined sintering cycle. Once the crystallisation smelting point is exceeded, the PTFE/TFM™ combines to form a homogeneous structure, achieving the desired chemical and physical properties as a result. After this process, our employees carry out a visual check of all unmachined parts. The product is then transferred to the final mould in an additional process step.
