What is Bronze Filled PTFE Tubes?
Bronze when used as filler, is added in percentages of weight between 40 and 60%. Bronze filled ptfe tubes has the best wear properties, remarkable compression strengths and good thermal conductivity, but poor electrical characteristics and chemical resistance. Bronze-filled PTFE is often used in hydraulic systems, particularly superb as linear bearings, slides, gibs, guide ways.Bronze filled ptfe tube are easily machined. Bronze-filled ptfe product is useful in applications which undergo high mechanical loads or high-speed rubbing contacts where the bronze filler supplies the strength and conductivity to carry away excess, unwanted heat.
Key Benefits
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 is not suitable for electrical applications. Bronze filled ptfe tube has high resistance to deformation under load, wear and cold flow. It is easily processed mechanically.
