Highly Durable Kynar® Film

Kynar® PGM TR 3-layer film is made of two outer surface layers of pure Kynar® PVDF sandwiching an inner layer of pigmented fluoropolymer alloy, which gives the characteristic white color.


The pure PVDF outer layer ensures a higher fluorine content than competitive technologies whose fluoropolymer content is often diluted by pigments and additives:


  • Kynar® 3-Layer PGM TR Film: ~59% fluorine in outer layer
  • Generic PVDF Films: <50% fluorine
  • Typical PVF Films: <41% fluorine
  • FEVE Coatings: <<40% fluorine – highly dependent on supplier


This outer layer surface ensures excellent weather resistance, fouling/dirt resistance, extended reflectivity, chemical resistance and outstanding burn/smoke resistance. Long term moisture barrier properties are proven to be outstanding.

Designed for Premium KPK® Backsheet Laminates

KPK® ("Kynar®/PET/Kynar®") backsheet laminates are comprised of a thick PET midlayer sandwiched between two 3-layer Kynar PGM TR film layers.


Over 25 years...

EPC (Engineering, Procurement and Construction) firms across the globe insist upon solutions that are specified and proven to meet the most extreme application conditions across the world. The proven legacy performance of Kynar® resins and films in some of the world’s harshest environments gives the end user confidence and peace of mind.


In 2014, the International Energy Agency predicted that solar power will be the world’s largest source of electricity by 2050. They stated that 25% of the total worldwide electrical energy demand will come from solar photovoltaics and concentrated solar power.  In order to meet these ambitious adoption records, Photovoltaic modules must demonstrate truly outstanding performance and durability.

Kynar® PVDF resins have been used in some of the most challenging material applications in the world for several decades.
