PRODUCT TECHNICAL DATA Saflex® Clear (R series) – 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 from Eastman Chemical Company, when in clear form, are branded as “Saflex Clear”. 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 Clear interlayers, have demonstrably met or exceeded many regulations for laminated safety glazing (including those listed above) when properly selected, laminated, and installed. Saflex Clear interlayers were specifically formulated to provide exceptional durability when exposed to natural weathering, especially when laminate edges are left unprotected from the elements. Saflex Clear interlayers have been shown to be compatible and durable when laminated in intimate contact with most infrared reflective, metal coated, ceramic frit and printed glasses. Compatibility should always be verified through the coating or ink manufacturer. The level of adhesion should be selected in order to meet specific applications requirements. A more detailed listing of Saflex Clear formulations can be found at www.saflex.com o r 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 Clear interlayers are supplied in a variety of roll lengths and widths. Most common standard roll length is 250 meters (820 feet). The most common thicknesses are 0.38 mm (0.015 inch), 0.76mm (0.030 inch), 1.14mm (0.045 inch) and 1.52mm (0.060 inch). Saflex Clear interlayers are produced in various adhesion levels to meet fabrication needs. Saflex Clear interlayers are available only as our conventional R series formulation in clear form. Saflex Clear 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 Clear interlayers 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: A Laminating Guide which details recommended practices for storage, handling and lamination is available to Eastman’s laminating partners. This technical guide is available only from a Saflex Technical Service (TS) Representative or Saflex Sales Manager.
