Prolonged exposure to the sun can weather even the most durable of surfaces.
In the past, acrylic was often chosen for plastic glazing applications because
of its inherent resistance to yellowing over time. But compared to
polycarbonate, the relative brittleness of acrylic made its impact strength
insufficient for demanding, vandal resistant applications.
To meet this need, Sheffield Plastics developed MAKROLON SL SunLife
polycarbonate sheet. It offers the best of both worlds—the impact protection of
MAKROLON sheet and the UV resistance of acrylic. Utilizing advanced
formulations combined with state-of-the-art extrusion technology, Sheffield
Plastics has created a tough, consistent quality product that will exhibit
superior performance for years to come.
The performance of MAKROLON SL has been well documented through years
of laboratory and field testing. In side-by-side comparative testing under
severe conditions, MAKROLON SunLife consistently outperformed
competitive materials utilizing older technology. Materials were also tested in
forms and bends well beyond recommended guidelines, proving that the integrity
of SunLife as well as its UV resistance will not change if the sheet is bent or
cold-formed. So conclusive was this testing that Sheffield offers a full
warranty against excessive yellowing, loss of light transmission and breakage.
