Glass for security and safety
Our Range of Products in This Series
The bulletproof glass is produced from polyvinyl butyral, polyurethane, sentryglas, and ethylene-vinyl acetate with customized thickness from 30mm to 70mm as per security required. Click here to download the brochure of “Jaipur Tuff Ballistics Resistant Glass”
Laminated glass is also a safety glass. A type of polymer layer is sandwiched between two or more layers of glass sheets. At the incident of breaking, it remains in place by that interlayer, generally, the interlayer would be polyvinyl butyral (PVB) or ethylene-vinyl acetate (EVA).
As per the many researches held on the performance of both PVB and EVA found, PVB preforms better.
PVB has very low yellowness index with high strength compare to EVA. Generally, PVB is highly recommended for laminated glass.
Laminated glass is produced in Jaipur Tuff by a heat pressure process on the fully automatic laminating line with integrated autoclave, boasts automatic loading and unloading, automatic glass positioning and a fully automatic online control system.
Jaipur Tuff practice world’s topnotch technology in lamination process. Our laminated glass is produced by world class LISEC Lamination line and highly qualified engineers.
Jaipur Tuff Laminated glass lends exceptional Safety and Security with very low visible distortion. It reduces heat, glare and sound while eliminating UV radiations.
Sentryglass has outstanding performance among all glasses, not only in security but in clarity, safety, yellowness index, delamination, open edge performance and many others.
|Sr. No.||Ionoplast Interlayer SentryGlas® (SGP)||PVB Interlayer|
|1||Ionoplast interlayer is an advanced interlayer with different chemistry specially invented for architectural applications||PVB interlayer was invented by DuPont for the automobile industry in 1930 for windshield applications|
|2||Young’s Modulus @ 30° C, E = 413 MPa|
Young’s Modulus @ 40° C, E = 187 MPa
Young’s Modulus @ 80° C, E = 3.96 MPa
SentryGlas® maintains a high Modulus value
as indicated by above values at all temperatures
|Young’s Modulus @ 30° C, E = 2.91 MPa
Young’s Modulus @ 40° C, E = 1.83 MPa
Young’s Modulus @ 80° C, E = 0.01 MPa
PVB has very low Modulus value as indicated by above values.
|3||It is not hygroscopic. It has better edge stability than PVB and can be used for open edge applications provided there is no accumulation|
|PVB being hygroscopic in nature absorbs moisture from the environment. It cannot be recommended for open edge applications.|
|4||0.89 mm calliper passes the ASTM E2353 – 06 test criteria due to its 100 times higher stiffness SentryGlas® was launched in this minimum calliper for this reason.||Minimum calliper required to pass the ASTM E 2353-06 test is 2.28 mm.|
|5||0.89mm Callipers can be laminated for Tempered glass as well.||A minimum of 1.52 mm calliper is required to laminate tempered glasses.|
|6||Has DIBT approval in Germany and France||No approval by DIBT for PVB for . coupling approach|
|7||Has a much better post breakage performance than PVB even at elevated temperatures ( > 40 C) studied through swing bag and drop bag tests. High tear strength provides safety against “Fall Through”||Poor post breakage performance and gives a “Wet Blanket ” effect. PVB interlayer tears away at rotules in point fixed glass applications thus not providing any “Fall Through ” resistance.|
|8||It can be used for making tempered laminated safety glass as the interlayer stiffness prevents panel fall out and “Wet Blanket” effect in point fixed applications||Not recommended in tempered laminated glass applications with point fixings as the interlayer cannot prevent “Wet Blanket” effect. Thus Its use can be limited to annealed or HS glass.|
|9||Yellowness Index is less than 1.5||Yellowness Index ranges from 6-12|
