MATERIALS: The High Performance Foams (HPF) Div. of Rogers Corp. has announced the global introduction of a new acoustic sound barrier material for demanding aircraft applications.The new BISCO® A2 Sound Barrier has been designed to meet challenging aircraft standards for flammability, smoke density and toxicity, and is already approved to the Airbus ABS5708 material specification. BISCO A2 is used to block the transmission of sound and demonstrates excellent performance in low frequency noise reduction.
An engineered solid silicone rubber, BISCO A2 provides excellent transmission loss performance in extreme environments while maintaining physical properties. BISCO A2 provides good temperature stability (-50 to 180C), outstanding flame resistance and low moisture absorption.
Innovative filler technology allows the A2 material to pass the aircraft radiant panel flame test FAR25.856 (a) from aeral densities of 1.2 kg/m² to 8.2 kg/m² (0.25 lbs/ft² to 1.68 lbs/ft²). Also appropriate for use in railcars, the BISCO A2 sound barrier is an extremely safe choice for acoustic insulation applications where extreme flame resistance is required.
BISCO A2 is available in a light gray color in a standard width of 1000mm in roll lengths of 5m and 10m. Samples are available upon request.

A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
