CIRCULUM® Standard grades

Our standard grades play an important role in people’s everyday life. Although they’re tiny and 98% of them is air, they offer vast possibilities and serve critical applications.

home/RAW/CIRCULUM® Standard grades

Combined into boxes, these beads keep salmon fresh from the sea to the dinner table. Our shape moulded packaging ensures that critical vaccines arrive safely at their destination. Through block moulding, our standard grades help provide optimal temperature in people’s homes. Their outstanding insulation capacity, high quality and moulding capabilities make them ideal for these applications, and many more. We’re happy to discuss your needs and offer the full power of our combined knowledge and capacity to meet them.
