US Patent:
20090242030, Oct 1, 2009
Filed:
Mar 26, 2009
Appl. No.:
12/411863
Inventors:
CYNTHIA H. KIRSCHNER - Beaumont TX, US
Jerrel C. Anderson - Vienna WV, US
Stephen J. Bennison - Wilmington DE, US
Richard Allen Hayes - Beaumont TX, US
David F. Kristunas - Townsend DE, US
Assignee:
E. I. DU PONT DE NEMOURS AND COMPANY - Wilmington DE
International Classification:
H01L 31/0256
US Classification:
136260, 136261, 136262, 136263, 136264, 136265, 428480
Abstract:
Provided is a high performance anti-spall laminate article comprising a bi-layer polymeric composite. The bi-layer composite includes a polymeric sheet and a poly(ethylene terephthalate) (PET) film laminated to each other. The PET film has a tensile modulus of about 600,000 psi or higher in both the machine direction (MD) and the transverse direction (TD), a shock brittleness index of about 55 Joules or higher in the machine direction and about 25 joules or higher in the transverse direction, and a percent elongation at break (EOB) of about 110-160 in the machine direction and about 60-110 in the transverse direction.

US Patent:
20090029174, Jan 29, 2009
Filed:
Jul 24, 2008
Appl. No.:
12/220633
Inventors:
Cynthia H. Kirschner - Washington WV, US
Jerrel C. Anderson - Vienna WV, US
Luther W. Center - Circleville OH, US
Charles Anthony Smith - Vienna WV, US
International Classification:
B32B 17/10
B32B 38/10
B32B 27/36
B32B 37/00
B32B 27/00
US Classification:
428413, 156247, 4284111, 428426, 428480, 156 60, 428447, 4284231, 428522
Abstract:
Provided is a process for manufacturing a glass/plastic laminate or a glass-less laminate having improved optical qualities. The process involves the use of a bi-layer film as a removable release liner. The bi-layer film comprises an inbound layer and an outbound layer. In the lamination process, the inbound layer is disposed adjacent to the plastic film outer layer and the outbound layer is disposed adjacent to a rigid cover plate. The polymeric material comprised in the outbound layer has a melting temperature that is higher than the temperature reached by the outbound layer in the lamination process. The melting temperature of the inbound layer is preferably at least 10 C. higher than the melting temperature of the outbound layer. Preferred bi-layer release liners include polyethylene/polypropylene films.
