Plastic Film Metallized Polyester Film Used for Capacitors

Plastic Film Metallized Polyester Film Used for CapacitorsOur company has 8 large-scale high vacuum coating equipment, 24 intellectualized slitting machines.  Professional manufactures variours formations of metallizded polypropylene & polyester film for capacitors use.Types of Metallized Layer:Base filmpolypropylene filmPolyester filmNormal thickness2.0μm ~12.0μm1.9μm ~12.0μmMargin typeSingle marginCoating metal Zinc-Aluminum alloyCoating side SingleEdge structure Heavy edge  Square resistance:            Normal film Width and MarginNote: If customer needs other resistance, film width or margin, please contact us.Inside/outside core diameter:  Inside core diameter/ToleranceOutside core diameter/Tolerance75mm+1/-0.5mm175220280320±25mm±20mm±20mm±20mmNote: A pair tolerance of outside core diameter ≤2mm.More type Metallised capacitor plastic film pictures:Metallised capacitor film Application:To produce all kinds of the film capacitorsMetallised capacitor film producinng and packing:Specifications of metallized film:Metallised polypropylene film (MPP Film):PropertiesUnitTypical valueDensityg/cm30.905±0.005 Thicknessµm2.0 ~ 12Tensile StrengthMD (MPa)≥100Elongation at BreakMD (%)20~200Elastic ModulusMD (MPa)2800Heat ShrinkageMD (%)≤5 ( 120°C, 10min)Wetting TensionmN/m38  (Corona treated side)Surface Roughnessµm0.08Melting PointºC172Volume ResistivityΩ.m>1015Break-dowm VoltageV/µm≥350 ( 23°C, DC )Dielectric Constant 2.2  (20ºC,1KHz)Dissipation Factor ≤4×10-4 (20ºC,1KHz )RCΩF≥5×104Metallised Polyester Film (MPET Film):PropertiesUnitTypical valueDensityg/cm31.4 Thicknessµm1015  ( 23°C, Humidity 50%)Dielectric Constant 3.2  (20ºC,1KHz)Dissipation Factor-≤60×10-4 (20ºC,1KHz )RCΩF≥1×104Packing:Film rolls are packed in plastic bags, vacuumed and put into desiccant for heat sealing.The Bags are marked with type labels, mark thickness width, free margin width and resistance.The bags are packed in carton cases.The cartons are wrapped by wooden cases or reinforced carton.Storage:Metallized film should be stored in its original package with temperature 5 - 35ºC and humidity less than 85%RH before using.Metallized layer is easily oxidized when exposure to moisture. Therefore, the film should be used as soon as possible when opened. The recommended temperature is 15 -25ºC with humidity less than 60%RH after openingWith original sealed package, and stored as mentioned above, the storage time can be as following: Al metallized film: 12 months from the delivery date. Al/Zn Alloy metallized film: As zinc is quite unstable , the storage period (from delivery date) depends on the resistance of the film:≤10 Ω/square: 6 months 10 ~30Ω/square: 3 months >30Ω/square: 1monthFAQ: Ask: Which type of the metallized capacitor film your factory producing ?Reply: Metallized polypropylene film & Metallised polyester film for capacitor use.Ask: What are the thickness you are producing ?Reply: Metallized polypropylene film from 2um to12um.      Metallized polyester film from 1.9um-12umAsk: If your factory could produce the wave cut metallized film ?Reply: Yes, we could be according to your requirement to wave cut.Ask:  For the metallized capacitor film are very easy oxidation, how do you protect the film and transport them safty to our factory ? Reply:  For our packing is as follows:1.Roll films are packed in vacuum plastic bag and heat-sealed with desiccants.2.Bags are marked with labels of types.3.The bags are packed in carton cases.4. The cartons are wrapped in wooden cases or reinforced carton.   5. If the goods are bad of packing problems,we will Indemnify the goods.Ask: what is the quantity for one 20ft container loading?Reply: usually 7-8tons.
