TDI and MDI are chemical substances widely used in the manufacture of polyurethane rigid foam and soft foam . In the automotive industry, polyurethane foam exhibits a variety of uses, providing important support for vehicle comfort, sound insulation, safety performance, sealing and caulking, and structural strength.
First, polyurethane foam plays an important role in the manufacture of car seats. It is often used as padding in seats to provide passengers with a more comfortable driving experience. This kind of foam can not only increase the softness of the seat, but also provide support and cushioning effects, thereby reducing body fatigue during long-time driving and riding, and improving driving and riding comfort.
Secondly, the structural properties of polyurethane foam make it an excellent sound and heat insulator . In automotive interior applications, it can effectively reduce the entry of external noise and create a quiet environment for the car. In addition, polyurethane foam can also provide good temperature insulation effect, which helps to maintain a comfortable temperature in the car, so that the occupants can enjoy a pleasant driving experience in all weather conditions.
Third, polyurethane foam is excellent in energy absorption. In the event of a car crash, it can be used as a safety device to absorb the energy released during a collision, thereby mitigating the impact of the collision on passengers and drivers. For example, the door trim panel of a car is one of the important parts of the car, which can be used to install various switch panels, storage, etc., but its most important role is the use of car safety: when the vehicle has a side collision, "Secondary collision" will cause the occupant to contact the interior panel, and the interior panel assembly can greatly absorb the energy of the occupants hitting the interior panel. In addition, the cushioning foam in the interior trim made of rigid polyurethane material has a high proportion of the energy absorbed in the overall energy absorption, so it is widely used in the door interior trim, and the door interior trim has also become a passive part of the car. Indispensable and important component in safety. This feature can significantly improve the safety performance of the vehicle and reduce injuries caused by accidents.
In addition, polyurethane sealants are widely used in the automotive industry, mainly for Automotive windshield sealing, caulk/weld sealing, structural sealing, interior bonding, floor bonding sealing, bonding and sealing of air-conditioned luggage compartments, and other bonding and sealing, etc.
It protects the interior environment of the car by preventing the penetration of moisture, dust and noise Neatness and tranquility.
In some cases, polyurethane foam can also serve as a structural component of automotive components. It not only enhances the rigidity and strength of components, but also does so without increasing the weight of the overall vehicle, thereby supporting the performance and durability of the vehicle.
Not only that, but for the new energy vehicle market, recent data have shown an exciting exciting trend. In July 2023, sales of new energy vehicles in eight European countries (UK, France, Sweden, Norway, Italy, Spain, Finland, Portugal) reached 109,000 units, a year-on-year increase of 47.8%, although a month-on-month decrease of 32.9%. This shows the vigorous development of the new energy vehicle market.
Specifically speaking, in terms of national markets, the UK has an eye-catching performance in sales of new energy vehicles. The month-to-month decrease was 21.9%, but the year-on-year increase was 71.3%, and the penetration rate reached 24.1%. France also achieved positive results. In July, sales of new energy vehicles increased by 50.9% year-on-year, with a penetration rate of 23.4%. Norway not only increased by 12.44% year-on-year, but its new pure electric vehicle tax policy also helps to promote the development of new energy vehicles.
In general, the multiple applications of polyurethane foam in the automotive industry and in Europe and The rapid development of the global new energy vehicle market jointly shapes the future of the automotive industry. Through continuous innovation and policy support, automakers and related industries can jointly promote a more environmentally friendly, more comfortable and safer travel experience.
