High-Density Slow-Rebound Memory Foam Sheet

High-density slow-rebound memory foam has significant slow-rebound characteristics. When subjected to external force, it can deform to evenly disperse the pressure and reduce local stress points. After the external pressure disappears, the material will slowly return to its original shape. This characteristic of strain lagging behind stress changes provides users with personalized support and wrapping feeling. It is especially suitable for side sleepers and can effectively reduce pressure on the shoulders and hips. The material is temperature sensitive and can adjust its hardness in different environments. In warm environments, the foam softens to provide better comfort, while in cold environments it stiffens to maintain some support. High-density slow-rebound memory foam has  energy absorption and shock-absorbing and anti-vibration capabilities, which can effectively reduce the interference caused by external impact or vibration and improve the comfort of use. The high-density foam structure gives the material durability and a long service life. It is not easy to deform and can maintain its shape and support for a long time. The synthesis process of high-density slow-rebound memory foam mainly includes chain growth reaction, foaming reaction and cross-linking reaction. By adjusting the raw material ratio and process parameters, foam materials with different properties and uses can be prepared. In order to improve certain properties of the material, such as yellowing resistance, flame retardancy, low temperature resistance, etc., functional modification can also be carried out. High-density slow-rebound memory foam is widely used in many fields due to its unique properties: Household items: such as mattresses, pillows, sofas, etc. Medical devices: such as anti-bedsore mattresses, orthotics, etc. Transport seats: such as airplane and car seats, etc. Sports equipment: such as football helmets, protective gear, etc.
