PRODUCT TECHNICAL DATA Saflex® UV – Polyvinyl Butyral Interlayer Saflex® interlayers are plasticized polyvinyl butyral (PVB) sheeting produced by Eastman and its affiliates. These interlayers are permanently bonded through a heat and pressure process to two or more pieces of glazing to produce laminates with impact and glass containment properties. Saflex R series formulations of PVB interlayers with Ultra-violet radiation screening of 99% up to 400 nm from Eastman Chemical Company are branded as “Saflex UV”. Laminated glasses with the properly selected type of Saflex interlayer are capable of being classified as safety glass in accordance with, but not limited to, various regulations such as ANSI Z26.1, ANSI Z97.1, AS/NZS 2208; CNS 1183, CPSC 16 CFR 1201, EN 12600 and ISO 29584. Product Overview: Saflex UV interlayer, product designation RB4U, has demonstrably met or exceeded many regulations for laminated safety glazing (including those listed above) when properly selected, laminated, and installed. Saflex UV interlayer was specifically formulated to provide exceptional durability when exposed to natural weathering, especially when laminate edges are left unprotected from the elements. Saflex UV interlayer has been shown to be compatible and durable when laminated in intimate contact with most infrared reflective, metal coated glasses. A more detailed listing of Saflex UV can be found at www.saflex.com or by contacting your local Eastman representatives. Available Forms: All Saflex interlayers are supplied in roll form on 15.2 cm (6 inch) diameter cores. Saflex UV interlayer is supplied in a variety of roll lengths and widths. Most common standard roll length is 250 meters (820 feet). The thickness is 0.76mm (0.030 inch). Saflex UV interlayer is available only in clear form and is designated as RB4U. However, it can be layered with Vanceva® colors to achieve almost any desired color with enhanced UV screening. Saflex UV is supplied in rolls as refrigerated or interleaved with polyethylene that do not require refrigeration (additional charge applies). Interleaving is not available for all products. Please contact your Saflex Sales Manager, Technical Service Representative, Customer Service Representative or visit www.saflex.com for further information. Storage Conditions: Saflex UV interlayer should be stored inside the moisture barrier bag that the roll is shipped in and maintained within the temperatures recommended in the Saflex Laminating Guide. It is recommended that the interlayer be used within a two- year period from purchase to minimize the sheet adhering to itself on the roll (blocking). Laminating Conditions: Eastman makes available to our fabricating customers, a Saflex Laminating Guide which details nominal methods for storage, handling, and lamination. This technical guide is available only from a Saflex Technical Service (TS) Representative or Saflex Sales Manager. To find the name of the Saflex representative for your organization, call 1-800-636-8670.
