High mechanical properties, chemical and thermal resistance, gas barrier, permanent antistatic

Poly(vinylidenefluoride), PVDF, is a flame retardant fluoropolymer showing excellent resistance to degradation caused by heat, corrosion and weather. Kureha is one of the largest PVDF producers since 1970 and its KF Polymer resin exerts high purity with very low level of extractables (Total Organic Carbons, metals and metal ions).


Films extruded wit KF Polymer will show excellent mechanical strength with very high resistance to abrasion and to external agents (chemical, thermal or weather), good transparency, intrinsic flame retardancy. KF Polymer shows very high barrier values to many gases, making it for example a preferred choice for the production of special tapes used for the internal lining of gas hoses, etc.


Specific PA6 and PA6.6 compounds for chemical resistance are available with Poliblend Polimid® and Ambra Ambramid® portfolios. Long-chain polyamides are available with Arkema Rilsan® and Rilsamid®, and Nexis Fibers PA6.10 and 6.12. Sipol Sipolprene® flexible films will also show high chemical resistance.


Arkema Evasin® EVOH polymer resin also has the highest oxygen-barrier properties, as well as to many other gases.


Permanent antistatic properties for anti-dust, comfortability, safety are achieved with Arkema Pebax® polyamide block copolymer antistatic additive plus Lotader® or Orevac® compatibilizer in proper mixing.


Multi-layer structures obtained by coextrusion, extrusion coating, extrusion lamination, thermoadhesive lamination or hot-melt lamination will yield very specific, high performance products.

Extrusion coating and lamination

Ambra with its long-term partner has a special expertise on all sorts of coextrusion, extrusion coating, extrusion lamination, coextrusion coating, thermoadhesive calandering processes.


Arkema Evatane® EVA shows strong adhesion on all PE, PS or PVC flexible supports, while Lotryl® or Lotryl® T copolymer guarantee very strong adhesion onto PP textiles or nonvowens.


The famous Arkema Orevac®, Lotader® reactive polyolefins are the first option for high adhesion in extrusion coating and extrusion lamination processes onto reactive or polar textiles, nonvowens and other flexible supports (PA, PET, natural fibers, etc.).


The same materials are used as well for extrusion coating and extrusion lamination on rigid supports, such as wood profiles, metal plates, glasses, rigid plastics sheets for a huge number of applications in construction, interiors furnishing, technical and industrial products, consumer goods, toys, etc.


All Arkema specialty polyolefins can be used as monolayer for coating, in multilayer coating, or also can be pre-mixed or directly dosed together with PE to tune properties.


Structures with chemical resistance and gas-barrier properties (Evasin®, KF Polymer, Sipolprene®, Polimid®, Rilsan®, Rilsamid®, Pebax®, Nexis Fibers, others) will always require adhesive tie-layers with reactive features, such as Lotader® or Orevac®.

Case Study

Arkema Lotader® is the elective adhesive layer for extrusion coating for the protection of all sort of id-cards, credit cards, etc. on any type of polymer support.

Thermoadhesive films

The Arkema copolymers portfolio is also widely employed for the extrusion of thermoadhesive films for the lamination of flexible, flexible to rigid, or rigid structures.


Arkema 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 Arkema 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.
