Bayer MaterialScience's Letter to customers

Bayer Substitute - Makrolon® UV (Enhanced UV stability grade)

Tuffak® XL weatherable polycarbonate sheet is a newer grade of polycarbonate sheet product from Altuglas International. It’s 300 times stronger than single-strength glass and significantly stronger than other transparent sheet materials.

Tuffak® XL polycarbonate sheet is produced via a proprietary process that creates a built-in UV barrier. As a result, sign makers using this sheet gain many advantages, including extended life of its impact properties, longer term yellowing resistance and higher light transmission over standard, general-purpose polycarbonate sheet.

Surface haze and yellowing will combine to reduce light transmission through a sign material. Tuffak® XL polycarbonate sheet retains a high degree of light transmission over standard polycarbonate, allowing your sign image to remain crisp and clear for a longer period of time.
