Farrat BR Materials Range BR4008TT BR4015TT HARDNESS (IRHD) BR = Nitrile (NBR) CR = Neoprene HM = Hamamat IS = Isofoam NR = Natural Rubber VR = Verlimber VM = Vidam SG = Squargrip T = Square Tread I = Isomat P = Plain AWTH WASHER High resilience High damping Low level of creep Tread pattern for improved grip and dynamic performance Manufactured by Farrat in UK Can be supplied as full sheets (1000x500 mm), cut to size pads and strips (including holes and slots if required) according to the customer’s requirements. Operating temperature range: -10 ºC to +80 ºC High resistance to oils & chemicals Applications Farrat BR materials can be used as anti-vibration & damping pads for a wide range of industrial applications. Impact machinery (e.g. PowerPress Elastomer Bearings for mechanical and hydraulic presses, turret punch presses, guillotines, etc.) General use for industrial machinery and hydraulic equipment Metal, timber and concrete production machinery Printing & packaging machinery Textile machinery Measuring, test and electronic equipment Mining equipment High-speed industrial doors Components, modules and systems in elevator industry Vibration control and damping gaskets for structures and machinery, when combined with Farrat AWTH and AWR Acoustic Washers. Damping pads on Farrat Wedgemounts & Jackmounts Note: These applications are a guide. The most suitable material will depend on the specific characteristics and constraints of your application Let us help you choose the right material for your application. Designing a resilient support or connection, and selecting a suitable material, can be complex. Without the correct consideration it is possible to adversely affect the performance of plant or machinery when incorporating a flexible support. Farrat offer a wide range of design and consultancy services, so please contact us with your requirements and we will work with you to find the right solution

Damping Ratio at Resonance vs. Pressure 1.1 The static and dynamic tests were in accordance with international standards: ISO 7743:2011 (E) and ISO 4664-1:2011 (E) although some factors were adapted to better suit typical applications of our customers. Please contact us if would like specific data or tests to be undertaken. 1.2 Optimum working pressure, (Po), is the pressure point where the natural frequency of the system, fn, starts to increase. Peak operating pressure, (PUS), is the pressure point from where the strain change would be much lower than the pressure change (de<<da). Farrat's elastomeric...
