Special combination material for cushion:
1. It has a continuous and dense surface layer and a high-strength honeycomb structure with interconnect wall with the obturation rate up to 95%;
2, waterproof, heat preservation, heat insulation, gas insulation, corrosion and other characteristics.
I. material introduction:
The foam holes of the cushion sponge are distributed in a mixture of diameters and sizes, with different thickness of the skeleton and a large percentage of holes. Under compression, different supporting forces will be generated under different deformation conditions. Therefore, the cushions and mattresses made by high-resilience sponge are more comfortable. Its products include high-grade car seats, sofa seats, office seats and so on.
