Dyneon Polytetrafluoroethylene TM Product Comparison Guide a 3M company Dyneon PTFE and ™ ™ Dyneon TFM PTFE ™ PTFE is the acronym for polytetrafluoroethylene and is sold by Dyneon under the Dyneon brand name. Dyneon entered the market as a worldwide leader in advanced fluoropolymer technology. In addition, Dyneon has earned a reputation as an industry leader in providing PTFE-based compounds that feature exceptional physical properties – providing thousands of solutions for some of the most difficult applications. ● ● ● ● very high thermal stability broad and excellent chemical resistance wide service temperature range excellent dielectric properties no embrittlement or aging Dyneon™ TFM™ PTFE, a second-generation PTFE with improved properties, allows new designs and processing methods to be used, especially in applications where high safety and reliability standards are specified. In comparison with classic PTFE products Dyneon™ TFM™ PTFE grades are distinguished by: ● ● ● ● ● Electrical/Electronic Engineering Excellent electrical insulation properties, very low dielectric constant, high thermal stability and flame resistant properties. Semiconductor Well suited for use in manufacturing equipment due to the ultra-smooth surfaces of machined components enabling reduced wash, rinse and dry cycles, exceptionally low ion extractables and fusibility. The linear molecular structure of classic PTFE is arranged in a helical configuration. The fluorine atoms sterically shield the carbon atoms. This structure, in conjunction with the high carbonfluorine bond energy, explains the exceptional thermal stability and chemical resistance of the material. Chemical Processing/Plant Construction Recognized for its corrosion protection and as a sealing material because of its broad and excellent chemical resistance and continuous service temperature ranging from -200 °C to +260 °C. Dyneon™ Polytetrafluoroethylene Suspension polymers Non-free-flowing grades unfilled and filled (compounds) Free-flowing grades unfilled and filled (compounds) Semi-finished and finished products Billets Skived films Rods Sheets Tubes Emulsion polymers Micropowders Dispersions Additives for plastics, lubricants and printing inks Non-stick and antifriction coatings Formulation of metal coating systems Impregnation Coating of glass fibre fabrics Fine Powder extrusion grades unfilled and filled (compounds) Tubing Unsintered sealing tapes Electrical insulating tapes Wire and cable insulation Lining Yarns Dyneon™ PTFE is supplied in the form of: ● The exceptional property profile of DyneonTM TFMTM PTFE is achieved by chemical modification and a specially tailored molecular structure. DyneonTM TFMTM PTFE bridges the gap between classic PTFE and DyneonTM PFA fluorothermoplastics. The DyneonTM TFMTM PTFE range of specially tailored suspension and emulsion polymers is continually being extended. 2 in modern types of roof membrane. Sliding bearings have proved themselves over the years in the building construction and civil engineering, for example as bridge pads. Construction Offers weathering resistance, non-stick properties and does not support combustion; used to advantage substantially lower deformation under load denser polymer structure lower permeability excellent weldability with special methods higher economic value PTFE is rapidly becoming the material of choice where low friction, high durability, excellent thermal properties and chemical inertness characteristics are required. Automotive Its outstanding properties make it ideally suitable for self-lubricating bearings, sliding elements and seals, especially when reinforced with special fillers. Consumer Markets For coating household utensils and engineering parts, the non-stick/slip properties and heat resistance are essential. The unique properties of polytetrafluoroethylene (PTFE) have made it an indispensable material for modern industry. PTFE offers the following exceptional characteristics: ● Dyneon™ PTFE meets tough demands for new applications and maintains proven success and high reliability in the following industries: ● Free-flowing and non-free-flowing compression moulding powders (suspension polymers) – unfilled and filled (compounds) with carbon, glass, bronze etc. For the manufacture of semi-finished and finished products, such as pipes, rods, sheets, skived films, linings and billets. Emulsion polymer powders (paste extrusion grades) – unfilled and filled (compounds) with glass, carbon etc. for processing on paste extruders. For the manufacture of wire and cable insulations, unsintered and sintered tapes, thin-walled tubings, pipe linings, sintered and unsintered cords and profiles. ● Dispersions: For impregnating yarns and woven fabrics and coating metal surfaces, an extensive range of different dispersions is available. ● Micropowders: Very fine-particle, low-molecularweight PTFE powders used as additives for thermoplastics, lubricants, printing inks, paint and coating systems to improve slip and non-stick characteristics. 3 Dyneon PTFE Dispersions ™ with bimodal particle-size distribution Significantly improved coating performance obtained by using DyneonTM PTFE Dispersions with bimodal particle-size distribution: ● ● improved film formation better adhesion ● ● ● far fewer pores better gloss higher hardness This principle is already being successfully applied in various DyneonTM PTFE Dispersions, e.g. DyneonTM TF 5050 Z PTFE, our best product for formulation systems and impregnation. Dyneon TFM PTFE ™ ™ a second-generation PTFE with improved properties An important further development on classic polytetrafluoroethylene is Dyneon™ TFM™ PTFE, a second-generation PTFE, which represents a unique extension to the Dyneon™ Fluoroplastics product portfolio. Skived films under a optical microscope at 25x magnification Dyneon™ TFM™ PTFE offers a significantly improved property profile: ● ● ● ● ● ● ● ● substantially lower deformation under load denser polymer structure with fewer voids lower permeability smoother surfaces of machined parts higher transparency excellent weldability with special methods meets many specifications (e.g. FDA compliance; UL94 listing) The denser polymer structure of DyneonTM TFMTM PTFE is apparent under the microscope. Monomodal particle-size distribution Higher packing density with bimodal particle-size distribution. The variable sized particles form a more tightly packed particle arrangement and thus produce a denser coating film. 4 5 Dyneon TM Polytetrafluoroethylene Powder properties Unit Test method Test specimen ASTM D 4894 , D 4895 , ASTM D 47457) 5) 6) Physical properties (typical values)1) Suspension polymer (compression moulding) powders Dyneon™ TFM™ PTFE – second-generation PTFE Selection of free-flowing compounds made from Dyneon™ PTFE and Dyneon™ TFM™ PTFE8) Dyneon™ PTFE TFM 1700 TFM 1705 TFM 1600 TFM 1610 TFM 1635 TFR 1502A TF 1750 TF 1620 TF 1641 TF 1645 TF 4103 TF 4104 TF 4105 TFM 4105 type III gr. 1 type III gr. 1 type III gr. 2 type IV gr. 1 type IV type VI type II type IV gr. 2 type IV gr. 2 type IV gr. 2 type II type II type II type II Bulk density g/l DIN EN ISO 60 410 410 820 760 825 800 380 870 840 840 820 820 820 820 Average particle size µm ISO 13320 25 25 450 430 230 800 25 220 450 450 500 500 500 500 non-freeflowing non-freeflowing very good free-flowing very good free-flowing limited free-flowing very good free-flowing non-freeflowing limited free-flowing very good free-flowing very good free-flowing very good free-flowing very good free-flowing very good free-flowing very good free-flowing 15 15 30 30 20 – 15 20 30 30 50 60 70 70 ASTM D 4895 ASTM D 4895 – – – – – – – – – – – – – – – – – – – – – – – – – – – – min.
