PTFE as the basis for gaskets of the newest generation... Numerous advantages make our PTFE-products an ideal and extremely versatile sealing material: chemical resistance from pH 0 – 14 temperature range from –240°C up to + 270°C (+310°C for short periods) high residual stress physiologically harmless conforms to FDA regulations non-ageing, UV resistant non-inflammable vacuum resistant ...perfected by special TEADIT® manufacturing processes Based on the production process The latest addition to our family expanded PTFE joint sealant tapes of our monoaxially expanded PTFE of ePTFE sealing...

Structured PTFE gasket material TF The TF range of PTFE gasket sheets are made from pure PTFE with special filler substances. Because of the multidirectionally orientated fibre structure of these PTFE-sheets, the problems usually associated with PTFE, like cold flow and creep, have been largely eliminated. Gaskets from those sheets can be used in considerably higher temperature/pressure combinations than conventional PTFE materials. Advantages - excellent compressibility - outstanding recovery - low hot creep during service - excellent sealability - drastically reduced cold flow and creep -...

Structured PTFE gasket material TF TF 1570 filled with hollow glass micro spheres colour: blue Special advantages - excellent adaptability - high compressibility - very good chemical resistance Application areas - suitable for pressure sensitive connections made of glass, ceramics, plastic etc. - compensates for irregularities, roughness and/or damages on the sealing areas - ll-round gasket material, specially suited for the a chemical and pharmaceutical industry Tests and approvals: TA Luft, FDA, BAM, GL, Blow-out test (VDI 2200) Technical data density (at delivery): = 1.7 g/cm³...

Welded gaskets Welded gaskets made from our TEADIT® TF sheets For over 20 years TEADIT has been welding large size PTFE-gaskets and PTFE envelope gaskets. We enhanced this practical knowledge, the technology and materials to provide customers with gaskets in big dimensions (larger than sheet size) made from our structured TF materials. Our precisely manufactured welded gaskets achieve the same tightness classes as gaskets made from one single piece. Application areas: - Equipment which requires gaskets bigger than the available sheet(s). - Bigger gaskets, where the focus is on material cost...

Multi-directional ePTFE gasket material TEADIT® 24 SH TEADIT® 24 SH is a gasket sheet produced from pure, multidirectionally expanded PTFE. A special production process ensures equal tensile strength in all directions. This makes gaskets cut from TEADIT ® 24 SH one of the best, most versatile and most reliable gasket materials on the market. Cold flow and creep have been eliminated, gasket parameters have been drastically improved, while all the excellent physical properties of PTFE have been fully retained. Advantages - material does not get wider under compression - easy to cut or punch -...

Mono-directional ePTFE gasket material TEADIT® 25 BI This top of the range PTFE joint sealant tape belongs also to the group of multi-directionally expanded PTFE sealing materials. Again, a very complex production process ensures equal rigidity in longitudinal and cross direction, resulting in high dimensional stability and extremely low cold flow, combined with excellent malleability and very easy handling. This makes TEADIT ® 25 BI particularly well suited for use with all pressure sensitive and stress sensitive connections, it also compensates for irregularities and/or damages on the...

Mono-directional ePTFE gasket material TEADIT® 25 BI installation instructions 1.) he sealing area has to be clean and free of grease. Damaged parts have to T be repaired or replaced. All bolts and nuts should be well greased. 3.) emove the backing paper from the adhesive strip R and stick the tape onto the sealing area, beginning at a bolt hole. 2.) ut the beginning of the tape with a sharp knife in a skived manner as shown C in sketch below. 4.) oin the two ends as shown in the sketch below. J Firstly the bolts should be torqued in a star pattern. This should be done in three stages,...

Mono-directional ePTFE gasket material TEADIT® 24 B TEADIT® 24 B is a high-grade PTFE joint sealant tape, produced by a special monoaxial stretching process from 100% pure PTFE. An adhesive strip - approved for use with foodstuffs makes installation quick and easy. Advantages Safety - chemically inert against most substances - covers a wide temperature range - non ageing, UV resistant - eliminates the risk of using the wrong gasket material Quick and easy installation - adhesive strip aides installation - excellent malleability compensates for irregularities - used tape can be removed...

Mono-directional ePTFE gasket material TEADIT® 24 BB TEADIT® 24 BB is the wider version of our universally applicable, 100% pure, expanded PTFE gasket tape. Although the fibres have a multi-directional orientation, tensile strength is considerably higher along the longitudinal axis. TEADIT® 24 BB is suitable to cut or punch gaskets from and has a full width adhesive tape on one side, approved for use with foodstuffs (also available without adhesive tape). Advantages - all physical properties of 100% pure PTFE - gaskets can be economically cut from the tape - intricate shapes can be cut or...
