DuPont Glass Laminating Solutions has launched an innovative, durable, highly transparent, polyethylene terephthalate (PET) film known as SpallShieldÂ CPET having a proprietary hard coat to ensure scratch resistance. It can be utilized as an exterior surface on glass laminates requiring spall protection.
Standard applications are in trains, buses for occupant and driver safety, in light-weight automotive skylights for fuel-savings as well as in buildings for additional protection against flying glass pieces especially during blasts, ballistic attack or vandalism
The innovative anti-spall sheet can be utilized on safety glasses of varying thicknesses along with a range of other laminating sheets, which include polyurethane (PU) and DuPontâ ButaciteÂ and polyvinyl butyral (PVB) sheeting. Recently, DuPont used a hard-coated film of this kind to create a pre-composited PET/PVB laminating sheet known as SpallshieldÂ.It is now possible for customers to make film composites with their own selection of materials, which can be used along with the SpallshieldÂ CPET surface film.
According to Ron Hull, DuPont Glass Laminating Solutions business director, the DuPontâ SpallshieldÂ CPET is an excellent product for clients who require scratch resistance and anti-spalling features in high-performance and threat-resistant safety glass. By offering the PET hard coat as a laminating sheet enables a large number of glass companies to use it for their range of shielding glass solutions ensuring lesser costs for the additional safety. The film is available worldwide. Standard roll width is 60 ” or 1.52 m having 820 ft or 250 m length. Sample rolls with 60 ” or 1.52 m widths and 164 ft and 50 m length are offered for production trials and physical testing.
