If the laminate is supplied with pressure sensitive adhesive, the laminate may be applied to the substrate with hand pressure or a roller and heat may be applied to facilitate stretching and forming over edges, corners and other three-dimensional features in the surface to be covered. Manufacture of the decorative laminate may be achieved in either a continuous process to produce rolls of up to yards or greater in length or in a batch or semi-continuous press process to produce sheets. Vinyl color layer was laminated to a fluoropolymer layer in the manner of example 1. The color layer is then laminated onto the surface layer at temperatures and pressures appropriate for the materials being employed. Next Patent High strength monoli Please check your email for login instructions it may take up to 24 hours. Revision Level Applicable NO. For more than two centuries, DuPont has delivered innovative solutions to tackle global challenges.
Example 2 Vinyl color layer was laminated to a fluoropolymer layer in the manner of example 1. Example 5 A decorative laminate was made according to the method in Example 3 using a 3 mil film of Lexan FR83 as the backing layer. Login above to view price. A 4 mil layer was sequentially laminated to a clear fluoropolymer layer on a polyester carrier in a continuous lamination process.

DuPont Agriculture offerings deliver global nutrition through higher crop yields and healthier foods while developing solutions to help meet the world’s energy needs. The clear surface layer is placed on top of the print layer. Weight reduction is particularly important in vehicles for mass transportation such as trains and commercial airliners.
See how our broad family of materials and global development experts can help the automotive industry reduce emissions and improve fuel economy, design, safety, and affordability. The 2 minute total heat release was Your request has been submitted. The resulting laminates had an average tear strength of 1.
DuPont offers a broad range of food protection products to help you meet the rigorous standards of your food safety programs For good adhesion the laminate must be heated above the melting or softening point of at least one of the component layers. Example 11 A layer of fluoropolymer, a 4 mil vinyl color layer, a 2 mil layer of film produced from Lexan FST resin, and a 2 mil PVF backing layer were laid up with a texture paper on the fluoropolymer face.
Durable, polyvinyl sschneller films that are used schnrller a long-lasting finish for pf exposed to harsh environments. When used as a surface layer, the engineering thermoplastic film thickness is preferably between 0.
Therefore, this product can only maintain two-dimensional formability and is therefore used, for example, in relatively flat laminate panels. DuPont Agriculture offerings deliver global nutrition through higher crop yields and healthier foods while developing solutions to help meet the world’s energy needs. Typical tear strength is 1.
A surface texture may be imparted into the surface of the decorative laminate by heating the laminate to near or slightly above the softening point of the surface layer. At DuPont, we’re focused on dynamic science that generates real-world solutions.
If this is not your username. Manufacture of schbeller decorative laminate may be achieved in either a continuous schneoler to produce rolls of up to schnellsr or greater in length or in a batch or semi-continuous press process to produce sheets. Alternatively, contact adhesive may be used to apply the laminate to a surface.
Tedlar® PVF films Aerospace Applications | DuPont USA
This application claims priority to U. Films based on polybutylene terphthalate such as Valox FR1, available from Sabic Innovative Plastics, may also be used. The present invention relates to decorative laminates incorporating flame retardant engineering thermoplastic films as either a surface layer, a backing layer or both. The color layer or layers are removed from release paper and placed on top of the backing layer and if a print layer is coated onto a color layer it is placed with print layer facing up.
The material produced a 2 minute total heat release of Recover Your Username Please enter the email address associated with your account to recover your username. Harmonized Tariff Schedule Code. Example 3 A layer of fluoropolymer, a 4 mil vinyl color layer and a 5 mil layer of film produced from Lexan FST resin were laid up with an epoxy texture plate or a texture paper on the fluoropolymer face. The present invention overcomes problems or limitations in the prior art by disclosing a thermoformable decorative laminate with high, and in some cases, improved tear and tensile strength while maintaining the highest required flame and smoke retardancy standards without substantially increasing the weight or density of the laminate.
Provisional Patent Application No.
At DuPont, we’re putting science to work in the food and beverage industry — improving the nutritional value of food, ensuring food safety, and finding smart, sustainable solutions to feed a growing population. Please enter any email address associated with your account. Flame resistance properties were measured according to FAR Flaming smoke measurements produced a smoke density of at 4 min Ds 4 min of Tear strength for this laminate was 2.
Example 1 Color layer was coated from a solution formulated with solution-grade PVC in MEK onto release paper on a reverse roll coater. The assembly is then placed between the platens of a heated press at sufficient temperature and pressure and for sufficient time to consolidate the layers of the construction and impart the texture onto the surface layer. The decorative laminate of the invention may be used to decorate the interior surfaces of buildings or vehicles for mass transportation such as trains or commercial airliners.
Thin layers of acrylic primer, ca 0. The thickness of the backing layer varies depending on the application requirements of the laminate but preferably is from 0. This will minimize loss of texture if the material is to be heated and formed in a subsequent forming step.
Please schnellerr for the sales rep approval. For example, pre-laminating the clear surface layer to a color layer in a continuous process can eliminate or reduce the risk of trapping dust or other airborne particles between the clear surface and color layer.
DuPont Performance Polymers can be that partner. A layer of fluoropolymer, a 4 mil vinyl color layer, a 2 mil layer of film produced from Lexan FST resin, and a 1 mil PVF backing layer were laid up with a texture paper on the fluoropolymer face.
