We are continuing with our blog series: Foams for Low Clamping Force Seals. This week we will review the features and benefits of Microcellular Urethane Foam.  Along with the many benefits this foam offers for low clamping force seals, it die-cuts cleanly and adheres to a broad range of pressure sensitive adhesives. 

Adding a gasket to seal a device, whether it is keeping out dust, air, water, or something else, seems like it would be an easy part of the design. However, there are many material options available for most gasket applications. Choosing the best material may require some research. This is why we are starting a blog series outlining the features and benefits associated with the various foams that fit into this large subset of gasket material options: Foams for Low Clamping Force Seals

We are starting this series with SILICONE FOAM.

Rogers PORON® Microcelluar Urethanes are tried and true materials for gaskets and seals. With excellent compression set resistance, this line of foam materials is easy to convert. They die-cuts cleanly and securely adhere to a broad range of pressure-sensitive adhesives. 

UL-94 V-0 Flammability Rating

Product designs of the future are required to meet increasingly rigorous specifications with safety in mind. One of these requirements is often a UL-94 V-0 flammability rating. UL 94 is a plastics flammability standard released by Underwriters Laboratories (UL) The standard classifies plastics according to how they burn in various orientations and material thicknesses. The UL V-0 classification means that burning stops within 10 seconds on a verticle part allowing for drops of plastic that are not inflames.   

Why is this important? More and more products across every industry include high-performing electronics. These electronic components generate heat.  It is important that materials that are designed into these products meet specific material standards, such as UL94 V-0. In particular, the HEV market requires advanced sealing performance while meeting very rigorous specifications for passenger safety. Visit our webpage that describes the solutions we provide for Electronic Vehichles. 

Rogers has recently released PORON® 4701-V0-M, which is specifically formulated to meet all requirements under UL94 for both V-0 and HBF flammability ratings.
