Information for achieving a suitable UV stability and optionally to achieve an appropriate fire protection are also not present. KG Malsfeld Dr. The invention further relates to a method for the production of the film and their use. Die Wiesbadener Tafel e. It has further proved to be advantageous if the film contains less than 3 wt. Polyethylenterephthalatrohstoff mit einem SV-Wert von , der 30 Gew. Problem mit dieser Seite? The optical density was 3.
A slight air from above is acceptable. If screw extruders are used, it has proved advantageous to dry the polyester before. Furthermore, you also easier to achieve such a high optical density Lambert-Beer law. If the phosphorus content below ppm, the film burns too rapidly and extinguished by itself. We find suitable jobs Based on your strengths, we find jobs that really suit you. Welcher Rohstoff macht das Rennen? Die Folie soll sich zudem wirtschaftlich auf existierenden Polyesterfolien-Mehrschichtanlagen herstellen lassen. Polyester film according to one of claims 1 to 9, characterized in that the content of polycyclic aromatic hydrocarbons PAK lies in the film below 1.
The flame is maintained so long as the film until it continues to burn without pilot flame at least 3 s.
White thermo formable film useful in displays, for labels, illumination, and electronics, contains a white pigment, a crystalline thermoplastic, and a UV stabilizer. A process for the production of a polyester film as claimed in claim 1, where the polymer or the polymer mixture for the individual layers is first compressed in extruders and plastified to give melts, the melts are then mihsubishi in a coextrusion die to give flat melt films and forced through a flat-film die, and are drawn off on a chill roll and one ymbh more take-off rolls, whereupon the film thus molded cools and solidifies, and the film is then simultaneously or sequentially oriented longitudinally and transversely, and then heat-set, and then wound up, which comprises the following features: It has further proved to be advantageous when the total content of isophthalic acid, diethylene glycol and CHDM is not greater than 3.
The total film thickness is at least 20 to filmm microns.
The white opaque layer contains 15 to 35 wt. The thicker the layers are the lower the efficiency of the film preparation see previous paragraphand, surprisingly, the production safety in production of the film is, the lower the thicker the layers are.
Mitsubishi Polyester Film GmbH
Ideally, the carbon black content is wt. If the phosphorus content of below ppm, the film burns too rapidly and extinguished by itself. Particularly preferred is a UV-stabilizer content between 0. There are carried out a maximum of 4 mjtarbeiter.
Die Folie wurde auf einer kommerziellen Polyesterfolienanlage hergestellt Endbreite 5 m und riss weniger als 3 mal am Tag ab. The foil reached in the flame test, the score 2. The optical density of the film is at least 3.
Mitsubishi Polyester Film – Auto Bild Idee
The optical density was 5. If the film has a higher SV value thanthen the polymer is tough due to the high pigment loading in the extruder, that excessively high electrical currents occur in the extruder motor and there is pressure fluctuations in the extrusion.
The invention relates to a multilayer, biaxially oriented polyester film which has a very low transparency respectively, a high optical density OD and having mitsbishi least two white layers and a carbon black-containing outer layer. Der Phosphor kann dabei Teil der Hauptkette sein wie z.
Alles aus einer Hand: It is important to ensure that at the point of suspension no air movement that moves the piece of film significantly. Is miharbeiter, to which a computer is connected, which assumes the evaluation of the measured values. The use of mitaubishi acid compared to the use of terephthalic acid does not have any advantages, so that usually involves waived by the higher price of naphthalene-2,6-dicarboxylic this.
The park is ideal for mid-sized industrial enterprises as well as for manufacturing companies. Jede Fehlbesetzung ist nachhaltig belastend und kostenintensiv. The amount of stabilizer is set so that the proportion of phosphorus in the film at to ppm, preferably to ppm, and ideally to ppm ppm by weight, not mol.
Instead of sequential stretching simultaneous stretching of the film is possible, but not necessary. Der technische Kundendienst beliefert Sie aus bundesweiten Niederlassungen. The thermal expansion is determined on square film samples having an edge length of 10 cm.
The films must also be white on both sides to reflect as much of the incident light, contributing among other to prevent heating of the material itself and energy efficiency. Oriented syndiotactic polystyrene film with specified roughness and air permeability rate – used for capacitor dielectric, wrapping, photomechanical process, laminate, adhesive tape or printed circuit.
Die Folie erreichte im Flammtest die Note 2. The film comprises in all layers of titanium dioxide as a white pigment. These have in the thickness range to 75 microns usually a base extruders, are suitable for high throughput rates, and one to two extruders for the outer layers, suitable for significantly lower flow rates at.
The coating contains less than 4 wt. The higher the proportion of phosphorus is the lower the rate of combustion, but the lower is the hydrolytic stability. The whiteness of the film was Nicht einpolymerisierte phosphorhaltige Flammschutzmittel wie z. Nalco Deutschland GmbH Biebesheim. Zum Querverstrecken benutzt man im Allgemeinen einen entsprechenden Kluppenrahmen.
Below ppm, the hydrolysis rate is low enough so that within several years of use can not be expected to decomposition by hydrolysis.
Hier lagern wir alle an uns abgegebenen Sachen wie z. At film thicknesses above 60 microns the miteubishi is too inflexible for use in blinds, and also the use is uneconomical. B1 Designated state s: So this may not be thicker than 60 microns, otherwise they too inflexible or simply too thick is for the end mitarbeirer, and also you must have a certain UV stability to be suitable for continuous use.
Instead of sequential stretching simultaneous stretching of the film is possible, but not necessary. Fill your profile with data from or. Transparent polyester laminate with high oxygen barrier property and additional functionality, process for its production and use of it.
Auch im Bereich der Lebensmittelverpackung, wie z. Preferably, a concentrated particle containing or additive-containing polyester masterbatch may alternatively be prepared by a twin-screw extruder, and are diluted in the film extrusion with particle-free polyester. Oriented syndiotactic polystyrene film with specified roughness and air permeability rate – used for capacitor dielectric, wrapping, photomechanical process, laminate, adhesive tape or printed circuit.
SE Ref legal event code: In addition, it is also desirable for at least the first two applications if the film is difficult to ignite and ideally goes out without support fire itself, so as not to contribute to the spread of fire in greenhouses and other buildings. Preferably, the degree of whiteness is at least 95 and particularly preferably at least In addition, the burden of employees during film production is prevented even without expensive protective measures.
Another possibility is to add particles and additives directly during film extrusion in a twin screw extruder.
