Modified PTFE

Derived from standard PTFE, a new product – modified PTFE – is created by co-polymerization with a small quantity of a perfluorinated modifier and reduction of the molecular weight.


Modified PTFE


Derived from standard PTFE, a new product – modified PTFE – is created by co-polymerization with a small quantity of a perfluorinated modifier and reduction of the molecular weight. Although modified PTFE can be processed by the same methods used for standard PTFE, it has a clearly improved profile of properties, such as reduced cold flow and permeation as well as smaller pore volume and a lower stretch void index (SVI).


Innovations in Plastics


For over 30 years, ElringKlinger Kunststofftechnik and FTL Seals have been technology leaders in the field of seals and engineering design elements. For our customers around the world, we develop and produce individual, user-oriented solutions from PTFE or PTFE compounds and other high-performance plastics as well as PTFE composite components, including plastics or metals. Our solutions successfully stand the test of the toughest requirements in the field – at high levels of cost effectiveness and reliability. PTFE – the material that provides the basis for technical solutions in a wide range of applications. Tailormade by the specialist. With superior properties offering a host of functional and cost benefits.


Standard


Standard PTFE, has an exceptionally wide thermal application range. It offers virtually unlimited chemical resistance as well as being resistant to light, weather and hot water vapor. It has very good sliding properties, good electric and dielectric properties, it is anti-adhesive and physiologically harmless.


Compounds


Compounds based on PTFE and modified PTFE are filled with glass fibers, carbon fibers, carbon, graphite, molybdenum sulfide, bronze or organic fillers (high-performance thermoplastics). Fillers are used to achieve a multiple of the material’s original wear resistance and thermal conductivity as well as a significant reduction of cold flow under load and reduction of thermal expansion.
