Polyurethane materials, as the "fifth largest plastic", are widely used in many fields such as chemical engineering, construction, consumer goods, and automobiles. Especially with the rise of new energy vehicles, technology and materials collide perfectly, making our lives more convenient and comfortable. At the same time, we have found that in recent years, consumers have increasingly high requirements for health and safety in the cabin. Although polyurethane materials have comparative advantages in product design and lightweight, they also have the release of volatile organic compounds (VOCs) and odors, which affect the air quality inside the car.
In order to better solve the odor problem of polyurethane foam, we have done a lot of work on odor screening. At present, the commonly used evaluation methods include artificial olfactory evaluation method, instrument detection method and odor detector detection method. Among them, the artificial olfactory evaluation method is the most commonly used method, which uses the nose to make sensory judgments and obtain results that are acceptable to most people.
Currently, the German automotive industry standard VDA 270 "Determination of the Odour Characteristics of Trim Materials in Motor Vehicles" is the most commonly used artificial olfactory evaluation method standard, and the evaluation is also relatively strict.
Changneng Technology has always been committed to reducing the odor level and residual VOC of polyurethane materials. After years of verification, our R&D team has successfully developed the first generation of ultra clean series products ChangWel® by carefully selecting raw materials, repeatedly optimizing formulas, and combining innovative "super pure" patented technology Make the odor level of the product better than the market average. And it has been successfully applied in scenarios such as automobiles, homes, and home decoration, creating a comfortable environment for consumers.
On the automotive application side, whether in the OEM or third-party testing, Changneng Technology's products have demonstrated excellent odor control effects, using ChangWel ® All foam products made of polyurethane combination materials have reached 3.0 odor level (VDA 270). The application of high-quality ultra clean technology has raised the air quality inside the cabin to a higher standard, providing passengers with a more comfortable and healthy riding experience.
Changneng Technology will continuously innovate around green, low-carbon, and sustainable development, making greater contributions to the sustainable development of the polyurethane industry and various end applications. Let's innovate together and redefine a better life!
