Why do new energy vehicles choose low VOC PP materials?

May. 13. 2019

VOC is one of the common air pollutants in non-industrial environments. VOCs in vehicles are mainly derived from new energy car carpets, plastic parts of inner dashboards, roof felts, seats and other glues used in decoration. Common VOCs are benzene, toluene, ethyl benzene, xylene, styrene, etc. These harmful substances are prone to cause imbalance of immune level, damage to the central nervous system, thus affecting the digestive system, and even cause cancer and genetic mutations. In new energy vehicles, due to their small space, limited air flow, and many organic materials, especially in the case of high temperatures, harmful substances are extremely volatile and cause great harm to human beings.


The plastics used in the interior of new energy vehicles are usually modified PP materials, usually prepared by adding modified materials to PP materials, generally including reinforcing fillers, toughening agents, inorganic photo catalysts, antioxidants, light stabilizers, etc. These modified materials preparation processes will directly affect the VOC level of the product.


Today's Low-VOC modified PP compound are an attractive option for new energy automotive interiors. Low VOC plastics are strictly controlled from molecular design, polymerization process, processing technology, etc., which greatly reduces the small molecules that are easily dispersed in the materials, making the materials more stable, less volatile, and meeting the requirements of low VOC.


Low-VOC modified PP compound for new energy vehicles can improve the air quality inside the vehicle, reduce air pollution inside the vehicle, and benefit human health in the long term.


Xinyite Plastic's PP+EPDM+TD Low-VOC modified PP compound has excellent mechanical property and good dimensional stability. At the same time, it has high heat resistance, low odor and low VOC, which is well recognized by clients. These material melt-blends the PP resin with an elastomeric such as EPDM, and disperses the elastomeric in the PP matrix by mechanical force, which can greatly improve the PP toughness. In addition, due to the high purity of the talc powder, the reasonable use of additives can reduce the production of small molecules and achieve the purpose of controlling odor.
