Ekonol Filled PTFE Products
PTFE products have excellent performance in chemical, thermal and electrical resistance, but their own creep characteristics also affect the working efficiency and service life.
PTFE products have excellent performance in chemical, thermal and electrical resistance, but their own creep characteristics also affect the working efficiency and service life. Therefore, modification of this property with related materials and technologies can increase the application of PTFE in more defensive fields.
Polyparahydroxybenzoic acid (abbreviated polybonzoate,structural formula PHBA,trade name Ekonol) is a kind of aromatic high polymer crystallization with excellent thermostability, chemical resistance, good thermal conductivity, good compression creep, high hardness, and excellent frictionperformances, it stands wear and tear, and almost has no corrosive effect for metal mould pieces. However, the property of Ekonol and PTFE could complement each other, which overcomes the creepocity of PTFE and the brieeleness of Ekonol.
Polybenzoate filled PTFE composite materials is mainly used for the production of high-temperature oil-free lubrication bearings, bearing pads, sliders, piston ring, gaskets and packings, especially the operation of thebearings in water and water vapor. It can be used for high temperature valvea, cocks, rails, mercury sealing materials, thrust rings,seats, bridge sliders and other parts.
