Hits: 521 img
Huawei and Samsung’s latest foldables feature hinges made of specialty silicone rubber, enduring 300,000 folds – a 50% improvement over previous generations. The material maintains elasticity from -40°C to 150°C, enabling "crease-free" folding with ultra-thin glass (UTG). Lab tests confirm 12MPa tear strength, outperforming traditional polyurethane.
Supply chain sources reveal hinge costs have decreased from 18% to 12% of total device value, driving retail prices down to $800 range. With Apple entering the foldable market, global electronic-grade silicone rubber demand is forecasted to grow 45% in 2024. Products-IOTA
