Madico’s Protekt Backsheets for PV Modules are the most vigorously tested backsheet on the Market!

At Madico we take pride in testing our products to exceed industry standards.  We have heavily invested in outfitting our facilities with the latest in state of the art testing equipment.  In doing so we ensure that our Protekt backsheet products perform at the highest level while providing safety for the life of the panel.   In addition, we rely on third party testing to further validate and certify our product reliability.

Most recently Protekt has undergone new testing to meet UL certification in the area of flame resistance and electrical insulation.

Madico Protekt has passed the material requirements for 5VB testing – UL 94 vertical burning test.  The 5VB test is a flame rating for plastic materials – the material is subjected to a flame ignition source that is approximately five times more severe than ignitions used in horizontal and other vertical flame tests; the specimen may not drip any flaming particles.

Additionally, Protekt has undergone The High-Current Arc Ignition (HAI) test it is expressed as the number of arc rupture exposures that are necessary to ignite a material when they are applied at a standard rate on the surface of the material.  HAI range means number of arcs that are assigned – the performance level category assigned are 0 -4 ranking.   The higher the exposure you receive with flame resistance the higher your product performs.  Protekt receive the highest ranking in HAI – flame resistance of 0.    In addition to the HAI testing for flame resistance, Protekt is been testing by other third party evaluators and has passed the ASTM E 162 for Flame Spread Index (FSI) and received a FSI range of 64.  These results offer a further sense of security to our customers.

The comparative tracking index or CTI testing done by UL is to measure the electrical breakdown tracking properties of an insulating material.   Protekt received the highest rated performance with a CTI value of 600.  Protekt is the thinnest backsheet on the market that boast the highest in dielectric strength ensuring safety and performance reliability.

Protekt has also under gone extensive testing in the area of Damp Heat testing,  as the industry standard from UL and TUV is 1000 hours of damp heat testing – Protekt exceeds this test by maintaining intact at 2000 hours.

Our commitment to produce the highest quality backsheets using state of the art technology with a “Leaner and Greener™” process enables Madico to have a robust supply chain with the most reliable PV Backsheets on the market.
