Carbon filled PTFE has excellent compressive strength, wear and chemical resistance. PTFE has a very high melting point and is capable of continued service at 500F (260 C). 0000076226 00000 n
When a filler ratio or type is unspecified, it is fair to assume this is the material. The type and percentage of carbon added to PTFE is a variable and is critical to material performance. The secret is knowing which is the right material for any given application and ensuring that is what is being supplied. Carbon Filled PTFE was developed to provide a PTFE based material with improved mechanical strength. trailer<] >> startxref 0 %%EOF 5 0 obj <> endobj 34 0 obj<, Presented courtesy of Aetna Plastics Corp. \(www.aetnaplastics.com\). ���OVU8L?��^i_��|�������i�w#����b[�.8 =���)�ciA,��|��O?

AT AFT we offer an almost limitless range of base materials and fillers to suit practically any application. Carbon in itself is a brittle material with poor wear properties and mechanical strength. PTFE on its own has excellent frictional properties, elasticity and wear resistance but relatively poor mechanical strength and tends to fail in high PV applications. 0000002463 00000 n The properties of 25% glass-filled and 25% carbon-filled PTFE grades are shown below for comparison purposes. As long as the gas being compressed is relatively clear of solids and liquids, you can expect favorable performance for this family of filled PTFE in the following gas service: HYDROGEN AMMONIA, NITROGEN ETHANE, NATURAL GAS PROPANE, … Commonly used in sealing applications ! The addition of Carbon Fibre to PTFE increases the compressive strength and wear resistance. It provides good thermal conductivity and low permeability. filled PTFE's maintain their excellent chemical and high temperature characteristics, while fillers improve mechanical strength, stability, and wear resistance. stream for ptfe and teflon@ surface treatment of ptfe ptfe sheet & film (see astm d3308) ptfe rods, molded & extruded (see astm-di 71 0) ptfe rod ptfe molded sheet or shapes ptfe skived tape filled compounds of ptfe molding & extrusion materials ptfe molding & ram extrusion materials ptfe skived sheets 5% carbon-filled ptfe skived tape 0000028263 00000 n ?�?>?�!|A��:������9a��~�v��-J�o�0��}ev���9j �6��?�W���M����&t NF�a���*�l�i�40�x}g�7��R�/8������*K�ɽS�˵֭R^��Z��y"J1��J��­�K��ف�58��J��+;'����+ɮ��_~���O�����W��p�UZ(������2�v�u��X\O����k�ف�-6�'�_�S�oM������΀�ή^_l7>F�yҽ��[���krv��{������?��ߡ�����������>`�:N���F*�U���Pl�������S����? 0000001013 00000 n
