Just how buoyant can a material be? In the case of a "new generation" of continuous cured and modified rubber compounds from Sentinel Products Corp., "they can outperform existing PVC/vinyl nitrile materials at a competitive price," according to Scott Smith, COO. The new elastomeric metallocene-based compounds, EMR(TM) 220FL, recently received UL recognition for personal flotation devices. They have a buoyancy rating of 60, provide softness properties similar to PVC/vinyl nitrile materials, and can be easily thermoformed into 3D parts. The compounds remain flexible at low temperatures, resist fungal and bacterial growth, and have high UV and chemical resistance. Sentinel Products Corp.: Product Code 4372
