Background

In automobiles, interior articles such as automobile foot pads, steering wheel covers, back-up pillow neck pillows, window films, seat cushions, trunk cushions and the like are all made of foaming materials. In addition, many interior articles in public transportation such as airplanes, subways, high-speed rails, buses, ships and the like are made of foamed materials, and in addition, some daily necessities and furniture articles are also made of foamed materials. In products made with foamed materials, safety and comfort are critical, which is not possible with ordinary foamed materials.

The common foaming material has poor elasticity, slow rebound and poor foaming weight plasticity. Therefore, it is necessary to develop a high resilience foam material having good elasticity, fast resilience and good foaming weight plasticity.

The high-resilience foam material has better shock resistance and flexibility; the tearing strength is good; the hardness is easy to adjust; the rebound resilience and the elasticity are good; the foaming has good plasticity, which means that the foam can be restored to the original shape immediately after changing the shape, and has good elasticity. Therefore, safety and comfort-oriented products made of foam materials are mostly made of high resilience foam materials.

However, the existing high resilience foaming material has the problems of too fast curing and unsatisfactory foaming, or the problem that the mold opening is delayed and the foaming material is easy to deform because the curing is slow.
