Cancarb Limited has published a Technical Bulletin that describes the advantages of incorporating Thermax® Thermal Carbon Black in various formulations of polystyrene (PS) foam. The study documents the dispersion and processing benefits of Thermax® and uses similar expansion, density, open-cell content, and compression properties as the control. Adding 4 wt.% thermal black resulted in a ~ 3% reduction in thermal conductivity and a ~ 14% reduction in thermal effusivity.
The Alpha Technologies AT10™ is a CE certified universal tensile tester for rubber, plastics, and additional materials. A table-top model with a maximum load value of 10kN, the AT10 performs tension, compression, peel, tear, adhesion, O-ring and other tests for quality control and R&D applications.
