UL94 V0 Flame Retardant Silicone Sponge Rubber

St. Gobain’s R-10400-M flame retardant silicone sponge is a unique expanded silicone sheet product. It has similar mechanical properties as standard silicone sponge rubber but with flame resistance, R-10400 holds an aggressive UL94 V0 flame rating. Silicone is a naturally heat resistant rubber, however without enhanced chemistry it is capable of burning in the presence of a flame. R-10400 may be used similarly to standard silicone sponge products such as enclosure gaskets, soft gasket, vibration dampening, environmental gaskets, and water sealing but also for application such as military and electronics that require a UL94 V0 flame rating or flame resistance.

Silicone Materials Selection Guide Updated

Stockwell Elastomerics updated Silicone Materials Selection Guide - a comprehensive guide offering insight on the properties and benefits of using silicone for gasketing, sealing, and cushioning applications. This guide details Stockwell Elastomerics’ silicone rubber materials offerings in closed cell silicone sponge, cast silicone foams, gum based solid silicone and liquid based solid silicone. In addition, many common pressure sensitive adhesives offerings and product-enhancing surface lamination options for silicone foam and silicone sponge rubber are listed. This updated Silicone Materials Selection Guide is a quick “go-to” reference for engineers and designers. Silicone has become the material of choice by engineers for critical gasketing and cushioning applications. This can be attributed to its wide operating temperature range, resistance to compression set (good memory), UV resistance and long life.

Stockwell Elastomerics offers fast-turn prototyping for most silicone materials, often utilizing its extensive water jet cutting capabilities to produce cut to size parts from customer supplied CAD files.

Rogers purchase of MTI / Groendyk Silicone Sheet Operations

One of Stockwell Elastomerics’ strategic channel partners is Rogers Bisco™ Silicone Materials Unit. Bisco is our leading provider of Silicone Foam and thin Liquid Silicone Rubber Sheet materials for gaskets, cushioning pads and custom components.

Rogers recently acquired certain assets of MTI’s Groendyk Silicone operations. Groendyk has been producing closed cell silicone sponge and solid silicone sheets for many years. MTI has been casting Open Cell Silicone Foam as well. Rogers’ acquisition will further enhance their leadership position in the marketplace and provide a presence in the closed cell silicone sponge market.

During periods of transition – there may be gaps in material availability of the traditional MTI / Groendyk Silicone Sheet product line. As situations occur – Stockwell Elastomerics may be able to help customers in tight inventory situations. See the following cross listing as a reference – we are glad to supply evaluation samples.

• MTI Siltec-SD can be matched by Bisco BF1000 lightweight silicone foam
• MTI MF8000 can be matched by Bisco HT800 medium density silicone foam
• MTI MF8500 can be matched by Bisco HT820 firm density silicone foam
• Groendyk 7104 can be matched by Cohrlastic® R10480-S soft closed cell silicone sponge
• Groendyk 7304 can be matched by Cohrlastic R10470-M medium density closed cell silicone sponge
• Groendyk 7404 can be matched by Cohrlastic R10470-F firm density closed cell silicone sponge
• Groendyk 7314 can be matched by Cohrlastic R10400-M medium density, flame retardant closed cell silicone sponge.
  
  Further – Stockwell has over 15 acrylic adhesives to aid in assembly of gaskets and cushioning pads.

Fluorosilicone – Fluorosilicone Sponge, Solid Fluorosilicone, Electrically Conductive Fluorosilicone

Fluorosilicone (FVMQ) is fluorinated version of silicone which gives this polymer superior chemical resistance. Fluorosilicone is used where extreme temperature ranges (relative to “rubber”) are required and where aggressive fluids may be present.

The Aerospace, Automotive and Green Energy industries often use fluorosilicone for its cross-functionality. Fluorosilicone has ability to maintain its mechanical properties over a wide temperature range, is UV and ozone resistant and has excellent chemical resistance particularly to fuels and oils.

Stockwell offers fluorosilicone in its many forms including solid fluorosilicone sheets, soft fluorosilicone sponge, molded fluorosilicone parts, and electrically conductive fluorosilicone (used for EMI gaskets). Sheet grades are readily die cut or waterjet cut on site. Similarly, fluorosilicone parts are molded onsite at Stockwell Elastomerics.

For more information about solid fluorosilicone gaskets, fluorosilicone sponge, or other gasket fabrication applications, please contact Stockwell at (215) 335-3005 or browse our website.
