Wanhua Chemical launched a new polyurethane product!

Recently, Wanhua Chemical announced that through technological innovation and continuous iterative upgrading, it has launched a low-density polyurethane roof system:

WANNATE® PM-8228E

WANEFLEX® 590F

Low-density system to meet the needs of lightweight development

High opening, high air permeability, providing excellent sound absorption performance

Low odor, low VOC, care for healthy driving experience

As a car NVH interior part, the car roof plays the role of sound insulation and heat insulation and also has a decorative effect. As consumers continue to upgrade their pursuit of driving safety, comfort and economy, the automotive industry is also putting forward higher requirements for the lightweight and sound-absorbing performance of roof materials.

Due to its excellent NVH performance, polyurethane foam has been widely used in the field of automotive roofs.

Hidden behind the roof finish, the low-density urethane roof system is invisible to the eye but helps the car

It is an important force to reduce the weight of the vehicle and improve the NVH performance of the vehicle.

Polyurethane (PU)

Polyurethane (PU), the full name of polyurethane, was first developed by German scientists in the 1930s. German scientists polycondensed liquid isocyanate and liquid polyether or glycol polyester to form a new type of material. . At present, the world’s largest MDI manufacturer is Wanhua Chemical.

The following figure shows the industrial chain of Wanhua Chemical Polyurethane:

Polyurethane is mainly divided into soft polyurethane and rigid polyurethane. Soft polyurethane mainly has a thermoplastic linear structure, which has better stability, chemical resistance, resilience and mechanical properties than PVC foam materials, and has smaller compression set. Good heat insulation, sound insulation, shock resistance and anti-virus performance. Therefore, it is used as packaging, sound insulation, and filter materials. Rigid polyurethane plastic is light in weight, excellent in sound insulation and heat insulation performance, chemical resistance, good electrical performance, easy to process, and low water absorption. It is mainly used in construction, automobile, aviation industry, and structural materials for thermal insulation.
