BETTER DIMENSIONAL STABILITY AND LOWERS CREEP, COLD FLOW AND WEAR
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.
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.
