Proud to be part of the Worthen family
Endurans™ Solar is a subsidiary of Worthen Industries -a family-owned, highly diversified manufacturing company headquartered in Nashua, New Hampshire, USA. Worthen Industries has been applying science and technology to develop high-quality adhesives, coatings, extruded films, and laminated products, since 1866.

Get ahead with our polymers & extrusion expertise
Co-extrusion is a single-step process with no adhesives that creates super-strong, multi-material sheets with the strength of a mono-layer and excellent adhesion (for example, to the junction box, encapsulant and frame).
Here at Endurans™ Solar we’re the global market leader in this technology, with decades of experience. What does this mean for you?
- Enhanced inter-layer strength: so high it can’t be measured by standard tests.
- Full control of, and flexibility in, the bill-of-materials. No unknown materials. No nasty surprises
- Environmentally friendly: no adhesives or organic solvents – so no crosslinking; and the potential for full recycling at end-of-life. Unlike laminated backsheet, co-extruded backsheets are thermoplastics and can be fully remelted, reprocessed and reshaped. It’s what we call circular-by-design.

Co-extrusion is a highly cost-effective process that delivers ultimate value for money.
