PU shaping sponge is a kind of molded high-resilience sponge. This material cotton is made of polyamide material, mixed with various additives such as foaming agent, and the pressure agent is put into a simple mold and heated to extrude sponges of different shapes. It is suitable for swivel sofa seat cushion, back cotton, and a small amount of armrests are also made of stereotyped cotton.

At present, the material density is 55#~60#, and its elasticity is more in line with relevant standards. The elasticity and hardness of the sponge can be adjusted according to different parts of the product. Generally, the seat cotton is higher in hardness and density, followed by the back cotton, and the pillow cotton is softer.

Of course, the sponge not only has pu high-resilience stereotyped sponge, but also special-shaped high-resilience sponge.

The polyether polyols used in high resilience sponges are generally end-capped with EO, and the polyether activity is relatively large. The diameters of the produced sponges are mixed in size, the thickness of the skeleton is different, and there is a large open porosity. The rebound force with different support forces is generated under different deformation states.

Advantages of high resilience sponge:

1. Good shock resistance and flexibility;

2. Good tear resistance;

3. The hardness is easy to adjust;

4. Good resilience and flexibility;

5. The foam has good remodeling properties (it can be restored to its original shape immediately after being changed, and has good elasticity);

6. Can be made into any shape;

High resilience sponges are mainly used in car seats, furniture, sofas, bedding, etc.

Therefore, sofas, cushions and mattresses made of high resilience foam can provide better comfort, that is, a more ideal comfort factor, and are ideal for car seats, sofa seats and office seats.

Does the high resilience sponge also have low, medium and high density?
