Low VOC Is The Environmental Protection Requirement For Automotive Polyurethane Materials
- Jan 22, 2018 -

Environmental protection is the innovation direction of polyurethane materials, but at present, the VOCs produced by the interior polyurethane foam, adhesive, paint and synthetic leather will affect the quality of the air in the vehicle.

The German DIN 55649 standard defines VOC as any organic liquid and / or solid that can spontaneously volatize at normal temperature and pressure. At the same time, the German DIN 55649 standard in the determination of VOC content, has made a limitation, that is, under normal pressure conditions, the boiling point or initial boiling point less than or equal to 250 ℃ of any organic compounds.

VOC is a volatile organic compound that has a huge impact on human health. When indoor VOC reaches a certain concentration, people may feel headache, nausea, vomiting and fatigue in a short period of time. In severe cases, convulsions and coma occur and people's liver, kidneys, brain and nervous system may be injured, causing memory loss Other serious consequences. When the car's VOC reaches a certain concentration, the damage to the human body is more obvious.

With the continuous improvement of consumers' requirements for odor VOCs in vehicles and the compulsory standard of air quality in vehicles, the VOC control of interior parts has become a challenge for all vehicle manufacturers, interior parts manufacturers and polyurethane materials companies.


"Functional optimization, lightweight, improved process efficiency, low VOC, low fogging." This is a requirement for the automotive industry to develop a polyurethane for the automotive industry. Lee Kuan Yew, a senior engineer at CNHTC (Hong Kong) Co., Ltd., believes that the SRIM process, low density, MDI modification technology and low atomization technology have become the focus of the automotive polyurethane industry.

"The car's internal environment, especially the smell of the car, has been classified as a new standard of comfort or not." Zhang Wei, deputy general manager of Jiangsu Meistech Co., Ltd. mentioned the indoor air quality of the upstream business Pay attention.
