PTFE Materials for Welding Platen Protection 

During the welding process, softened or molten PVC can adhere to the heated platens of the welding machinery. Over time, this build-up can affect production efficiency, increase cleaning requirements and contribute to inconsistent weld quality. 

Teastech supplies high-performance PTFE sheets that provide an effective non-stick release surface between the PVC profile and the welding platen. 

With temperature resistance of up to 260°C / 500°F, these materials are well suited to demanding uPVC welding applications. 

Supporting Reliable and Efficient Production

The combination of temperature resistance and excellent release properties provides a number of practical benefits for uPVC window and door manufacturers. 

The easy-to-clean, non-stick surface can also help reduce downtime associated with cleaning and maintenance. 

PTFE welding sheets can help to: 

  • Prevent melted PVC from sticking to welding platens 
  • Reduce material build-up on machinery 
  • Protect welding plates from contamination and wear 
  • Reduce the risk of weld defects caused by contaminated surfaces 
  • Simplify cleaning and routine maintenance 
  • Support consistent production across high-volume manufacturing processes 

Suitable for a Range of Welding Processes 

The PTFE materials supplied by Teastech can be used across a variety of hot plate welding processes and equipment configurations. 

They are suitable for applications including conventional hot plate welding, RF systems and microwave welding processes, subject to the requirements of the individual installation. 

Our team can advise on the appropriate material and fabrication specification for the particular machinery and production environment. 

Product Options

Fabricated to Suit Your Machinery 

Sheets can be customised to meet specific requirements, including dimensions, shape and material specification. 

This allows manufacturers to source both the specialist PTFE material and the required fabrication from a single supplier. 

Teastech can manufacture a wide range of fabricated welding sheets from stock, allowing the material to be supplied ready for use within the customer’s production equipment. 

Discuss Your uPVC Welding Application

If you require replacement welding sheets, are reviewing material performance on an existing production line or need a customised fabricated solution, contact the Teastech team to discuss your requirements.

We can advise on the most suitable material and manufacture the finished sheets to suit your machinery and application.
