The addition of Bronze to PTFE gives better dimensional stability and lowers creep, cold flow and wear. It increases hardness and compressive strength whilst also increasing thermal and electrical conductivity.
EXPERIENCE & CAPABILITY
Here at Fluorotec, we have serviced many customers who have trusted us to machine bronze filled PTFE sheets into a whole range of components, including piston rings, compressor parts and high-performance slide plates utilising in-house CNC machinery. Whether it is machined parts, PTFE tubes and rods, or bespoke PTFE coatings, our expert engineers can solve any problems you may be having.

BRONZE FILLED PTFE PROPERTIES
Bronze Filled PTFE is reinforced with bronze powder with the percentage varying between 40% and 60%, resulting in a very hard-wearing material. It has weaker chemical resistance than other grades of PTFE and isn’t suitable for electrical applications.
Extremely hard-wearing material
Very heavy – high specific gravity
Electrically conductive
The best wear properties of any filled PTFE
Great deformation strengths
Good thermal conductivity
Not suitable for electrical applications
Poor chemical resistance
