Thermoadhesive films
The SK copolymers portfolio is also widely employed for the extrusion of thermoadhesive films for the lamination of flexible, flexible to rigid, or rigid structures.
SK Evatane® EVA special grades with superior transparency and aging resistance are used for the extrusion of thermoadhesive films for the encapsulation of crystalline silicon cells in photovoltaic panels, and for the construction of glass sandwich stuctures in interior and exterior architecture with outstanding safety, exhibiting also great properties for optical decoration.
Even stronger lamination adhesion levels may be obtained with SK Orevac® T or Lotader® thermoadhesive films, alone or blended with Evatane®, Lotryl® or common PE.
Applications will include all those mentioned in the above sections, for textiles, automotive, constructions, furnishing and many more.
Arkema Platamid® crystalline copolyamide (COPA) guarantees very high and universal adhesion to leather, textiles or polar substrates, excellent laundry & dry-cleaning resistance, and fast setting time (thus, fast lamination speed). Platamid® also has a high bio-source content, due to its origin from castor oil. Specific grades for film extrusion allow very thin films thickness (15µm).
Thermoadhesive films made with specific Platamid® grades will exert a durable adhesion onto natural fibres (cotton, wool, etc.), synthetic fibres (nylon, polyester, etc.), leather, wood, metals, NBR.
Platamid® films are also widely used for the decoration of clothes and textiles in the so-called Melt Print Transfer process, with superior laundry & dry-cleaning resistance.
