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. | 10-01-2009 |
20090324935 | TRANSPARENT LIGHT-WEIGHT SAFETY GLAZINGS - Provided is a transparent and light-weight ballistic resistant safety glazing comprising an ionomer sheet. The ionomer sheet comprises an ionomer derived from a parent acid copolymer that comprises copolymerized units of an α-olefin having 2 to 10 carbon atoms and, based on the total weight of the acid copolymer, about 20 to about 30 wt % of copolymerized units of an α,β-ethylenically unsaturated carboxylic acid having 3 to 8 carbon atoms. The ionomer is neutralized to a level of about 5% to about 90%, based on the total carboxylic acid content of the acid copolymer, and further comprises at least one cation. Further provided are articles comprising the light-weight ballistic resistant safety glazing. | 12-31-2009 |
20100062236 | TRANSPARENT LIGHT-WEIGHT SAFETY GLAZINGS - Provided is a transparent and light-weight ballistic resistant safety glazing comprising an ionomer sheet. The ionomer sheet comprises an ionomer derived from a parent acid copolymer that comprises copolymerized units of an α-olefin having 2 to 10 carbon atoms and, based on the total weight of the acid copolymer, about 20 to about 30 wt % of copolymerized units of an α,β-ethylenically unsaturated carboxylic acid having 3 to 8 carbon atoms. The ionomer is neutralized to a level of about 5% to about 90%, based on the total carboxylic acid content of the acid copolymer, and further comprises at least one cation. Further provided are articles comprising the light-weight ballistic resistant safety glazing. | 03-11-2010 |
20100112356 | HIGH CLARITY LAMINATED ARTICLES COMPRISING AN IONOMER INTERLAYER - A safety laminate comprises an interlayer that comprises an ionomer that is the neutralized product of a precursor acid copolymer. The precursor acid copolymer comprises copolymerized units of a first α-olefin having 2 to 10 carbon atoms and about 20 to about 30 wt % of copolymerized units of a first α,β-ethylenically unsaturated carboxylic acid having 3 to 8 carbon atoms; and has a melt flow rate of about 10 to about 4000 g/10 min. When neutralized to a level of about 40% to about 90% and when comprising counterions that consist essentially of sodium cations, the precursor acid copolymer produces a sodium ionomer that has a melt flow rate of about 0.7 to about 25 g/10 min and a freeze enthalpy that is not detectable or that is less than about 3.0 j/g. The ionomer composition may further comprise a second ionomer that has a melt flow rate of about 10 g/10 min or less. | 05-06-2010 |
20100154867 | MECHANICALLY RELIABLE SOLAR CELL MODULES - A thin film solar cell module comprising thin film solar cells deposited on a first float glass sheet, an ionomer encapsulant sheet and a float glass protective sheet. | 06-24-2010 |
20100167061 | LAMINATES COMPRISING IONOMER INTERLAYERS WITH LOW HAZE AND HIGH MOISTURE RESISTANCE - A laminate comprises an ionomeric interlayer sheet which, in turn, comprises or is prepared from a sodium/zinc mixed ionomer that comprises carboxylate groups and a combination of counterions that consists essentially of sodium cations and zinc cations. The sodium/zinc mixed ionomer is the neutralization product of a precursor acid copolymer. The precursor acid copolymer comprises copolymerized units of an α-olefin and an α,β-ethylenically unsaturated carboxylic acid, and it has a melt flow rate of about 70 to about 1000 g/10 min. In addition, the precursor acid copolymer, when neutralized to a level of about 40% to about 90%, and when comprising counterions that consist essentially of sodium ions, produces a sodium ionomer that has a freeze enthalpy that is not detectable or that is less than about 3.0 j/g, when determined by differential scanning calorimetry. | 07-01-2010 |
20130139886 | HIGH PERFORMANCE ANTI-SPALL LAMINATE ARTICLE - 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. | 06-06-2013 |
20150158986 | POLYMERIC INTERLAYER SHEETS AND LIGHT WEIGHT LAMINATES PRODUCED THEREFROM - Provided herein are interlayer sheets formed of an acid copolymer composition, which comprises an acid copolymer resin or an ionomer that is the neutralized product of the acid copolymer resin. The acid copolymer resin comprises copolymerized units of an α-olefin having 2 to 10 carbon atoms; about 10 to about 25 wt % of copolymerized units of a first α,β-ethylenically unsaturated carboxylic acid having 3 to 10 carbon atoms; and about 15 to about 30 wt % of copolymerized units of a derivative of a second α,β-ethylenically unsaturated carboxylic acid having 3 to 10 carbon atoms. In addition, the acid copolymer resin has a melt flow rate of about 1 to about 400 g/10 min. Light weight safety laminates comprising these interlayer sheets are characterized by good strength and superior acoustic damping, due to the properties of the acid copolymer composition. | 06-11-2015 |
