Product Description Kel-F? (PolyChloroTriFluoroEthylene) is a fluorocarbon based polymer and is frequently abbreviated as PCTFE. PCTFE combines physical and mechanical properties, non-flammability, chemical resistance, near zero moisture absorption and excellent electrical properties not found in any other thermoplastic fluropolymer.Kel-F? also known as PCTFE or CTFE has many of the properties similar to other fluoropolymers such as PTFE, FEP, or PFA, but is mechanically superior in rigidity and has very low gas permeability.Kel-F? maintains an outstanding electrical-insulating capability through thermal cycling and in high humidity environments. This material's high compressive strength and dimensional stability make it a good choice for structural material, while its low outgassing rate and permeability make PCTFE a great choice for laboratory, aerospace, flight applications, and instrumentation.Please Note: The Kel-F? brand belongs to 3M, but their production was discontinued in 1995. The only remaining resin is made by Daikin Industries of Japan and called Neoflon?.NEOFLON PCTFE M-300H is a high hardness fluororesin with excellent gas barrier properties.Introduction- NEOFLON PCTFE M-300H is a polymer with a structure in which all hydrogen atoms of polyvinyl chloride (CH2 --CHCl) n are substituted with fluorine atoms.It is in the form of one chlorine atom in PTFE structural unit.- Highly transparent due to this chlorine atom. - It is a fluororesin with the highest gas barrier property and high hardness.- Excellent in mechanical properties, although it is slightly inferior to PFA and FEP in heat resistance and chemical resistance.- M- 300H can reduce the mold volume during compression molding of thick molded products. Because it is granular.- Compression molding and extrusion molding are suitable. Product DescriptionPCTFE is a homopolymer of chlorotrifluoroethylene. PCTFE is melt processible and can be extruded or molded. PCTFE has a number of unique properties. In addition to excellent thermal and chemical stability, it has very low moisture absorption and permeation. It also is highly resistant to cold flow, is very rigid, is tough, has excellent dimensional stability and extremely good low temperature properties. It is especially applicable as a valve component material in cryogenic fluid service.PCTFE Main Advantage:Especially suitable for cryogenic applicationsExcellent resistance to creepDimensionally stable over a wide temperature rangeExtremely low gas permeabilityFDA approvalTransparent and coloured compoundsWorking temperature from -240°C to +180?C PCTFE - Poly (chloro trifluoro ethylene) TYPICAL PROPERTIESPCTFE - Poly (chloro trifluoro ethylene) TYPICAL PROPERTIESPropertyValueUnitsMethodMECHANICAL PROPERTIESTensile Strength4860 - 571034 - 39psiMPaD 638Elongation100 - 250%D 638Flexural Strength, 73°F9570 - 1030066 - 71psiMPa Flex Modulus200 - 243 x 1031.4 - 1.7psiMPa Impact Strength, Izod, 23 deg C2.5 - 3.5ft-lb/inD 256Compressive Stress at 1% deformation,1570 - 186011 - 13psiMPaD 695Density2.10 to 2.17gm/cu.cm THERMAL PROPERTIESCoefficient of Linear Expansion7 x 10-5K-1 Melting Point410 -414210 - 212deg Fdeg C Thermal Conductivity1.450.84Btu·in/h·ft2·°FW/m·KASTM C 177Specific Heat0.220.92Btu/lb/deg FkJ/Kg/deg K Heat Distortion Temperature, 66 lb/sq.in (0.455 MPa)259126deg Fdeg CD 648Processing Temperature620327deg Fdeg C ELECTRICAL PROPERTIESDielectric Strength, short time, 0.004"3000Volt/milD 149Arc-Resistance360secD 495Volume Resistivity, @ 50% RH2 x 1017ohm-cmD 257Surface Resistivity, @ 100% RH1 x 1015Ohm sq-1D 257Dielectric Constant, 1 kHz2.6εD150-81Dissipation Factor, @ 1 kHz0.02 D150-81OTHER PROPERTIESWater Absorption0.00% increase in weightD570-81Flame Rating+Non-flammable D 635Coefficient of friction D 1894Specific Gravity2.10 to 2.17 D792Moisture Permeability Constant0.2g/m, 24 hours O2 Permeability1.5 x 10-10Cc, cm/sq.cm, sec, atm N2 Permeability0.18 x 10-10Cc, cm/sq.cm, sec, atm CO2 Permeability2.9 x 10-10Cc, cm/sq.cm, sec, atm H2 Permeability56.4 x 10-10Cc, cm/sq.cm, sec, atm + Numerical rating for flame spread is not intended to reflect hazards presented by this or any other material under actual fire conditions MaterialBrandSize (Rod)ServicesApplication PCTFEMBHDia. 4 /5/6/7/8/9/10/13/16/18/22/25/26/40/45/50/55/sheet/rod extrusionand machiningand plastic modified servicesmedical, pharmaceutical,and semi-conductor, Aerospace, Auto etc. Detailed PhotosOur AdvantagesCompany ProfileCertifications Packaging & Shipping
