Product HuntTrosifol® Sound Control: Advancedacoustic interlayer from KurarayDistributed By Saugaat In India, Product Available As Single Layer InThicknesses Of 0.76 mm & 1.52 mmTrosifol SC from Kuraray is an advanced acoustic PVB interlayer that is based on monolayertechnology and has a great competitive edge over the conventional acoustic PVB based onmultilayer technology.Trosifol SC is available as asingle layer in thicknessesof 0.76 mm (for heatstrengthened glass) and 1.52 mm(for fully tempered glass). Withthe monolayer technology availablein 1.52 mm thickness, there is noneed for the laminators to stackacoustic PVB with clear PVB toachieve 1.52 mm calliper desiredfor fully tempered glass laminateconstructions.Basic differences between advanced acoustic PVB and conventional acoustic PVB.Advance Acoustic PVB(Monolayer Technology)It’s a homogeneous monolayer. Available in 0.76 & 1.52 mmImproves acoustic performance by 3dB compared to standard PVBStacking not required as 1.52 mm thickness is available. Normal de-airingprocess is sufficient as there are no interfaces.No ice flower defects as structure is homogeneous.Has a high adhesion that makes it ideal choice for tempered glass.No optical distortionConventional Acoustic PVB(Trilayer Technology)Based on trilayer technology. Softer core layer is sandwiched between two layers of standard PVB. Itsavailable in 0.76 mm thicknessImproves acoustic performance by 3 dB compared to standard PVBRequires stacking with 0.76 mm Clear PVB to achieve 1.52 mm. A good de-airing process is necessaryto remove entrapped air pockets between the interfacesVulnerable to Ice Flower defects due to heterogeneous structure of the interlayerBest suited for automotive applications that make use of annealed glass laminates. Does not have ahigh adhesion and thus not suitable for tempered glass laminates.Optical distortion is apparent when used laminated IGUsFigure showing “Ice Flower” defect in alaminated glass made with conventionalacoustic PVB interlayer.48 Glass Bulletin | January - March, 2021
Kuraray• 2Figure showing Acoustic performance comparison for singleglass, laminated glass with Trosifol® PVB (Standard) &Trosifol® SC (Monolayer) Advanced Acoustic PVBAbout KurarayKuraray was founded in 1926 for thepurpose of commercializing syntheticrayon, which was cutting edgetechnology at the time. In 1950 duringthe post-World War II period, as Japan’sfirst domestic producer of syntheticfiber based on original Japanesetechnologies, Kuraray became a worldleader in the commercialization of PVA(poval) fiber under the KURALONbrand, ushering in Japan’s pioneeringera in the chemical synthetic fiberindustry. Kuraray Group are committedto opening new fields of business usingpioneering technology and contributingto an improved natural environmentand quality of life.Kuraray products are marketedand sold in India by the company’sauthorised distributor Saugaat Inc(west India)About Saugaat IncFounded in 2016, Saugaat Incis involved in different businessactivities, glass being the core source ofbusiness.
