Kynar® PVDF Film and KPK® Backsheet

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.


Premium KPK® Backsheet Laminates

KPK® (Kynar® PVDF/PET/Kynar® PVDF) backsheet laminates are comprised of a thick PET mid-layer 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. 

KPK® and KPE® are registered trademarks of Arkema.


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

Application: Focus on Cable Ties

Outdoor photovoltaic cable management systems require durable cable ties which can withstand a variety of severe environmental conditions. Kynar® PVDF cable ties maintain mechanical integrity at both high and low temperatures, even after continuous exposure to UV radiation. Additionally, the excellent abrasion resistance of Kynar® PVDF makes the cable ties extremely resistant to mechanical damage caused by installation, sand, and debris. Are your standard cable ties failing? Upgrade to Kynar® PVDF cable ties today!
