The Fifth China International New Material Industry Expo concluded on Sept 8. The ETPU micro-hole popcorn bead super elastic material developed by Harbin Engineering University has attracted wide attention in the industry. It’s said this kind of material can be applied in tires to raise the safety and flexibility greatly.
