Description

Technical Field

[0001] The utility model belongs to the technical field of silicone sheets, and in particular relates to an organic silicone leather silicone foam. Background Art

[0002] Silicone foam, also known as expanded silicone, is a high-resilience, low-density organic material that offers high and low temperature resistance, low compression set, and superior mechanical fatigue resistance. It is also environmentally friendly, odorless, waterproof, fireproof (V-0), mildew-proof, antibacterial, has a wide operating temperature range, and can be adhesively bonded to other materials. With the increasing international focus on environmental protection and public awareness of health, more and more silicone products are entering our lives and are now widely used in various industries.

[0003] Traditional car seat cushions, sofa seat cushions, etc. are all filled with PU or PVC foam. Toxic substances are added during the production of PU / PVC, which will continue to evaporate in the natural environment such as sunlight, affecting the air quality of the use environment. PU / PVC is easy to ignite, and the added flame retardants not only affect the environment, but also have no real effect and cannot guarantee safety. After long-term use or storage, the residual solvents and plasticizers in PU / PVC are continuously released, which is very harmful to human health. Utility Model Content
