With the development trend of automobile lightweight, the proportion of modified plastics used in automobiles is increasing. Automotive plastic interior parts have the characteristics of safety, environmental protection and comfort. The use of elastomers and foamed plastics that can absorb impact energy and vibration energy to make dashboards, seats, headrests and other products can reduce the damage to the human body during a collision. Improve the safety factor of the car. According to statistics, the amount of plastic used in automotive interior parts has accounted for about 50% of the total amount of plastic used in the vehicle. Automotive plastic interior parts especially emphasize the sense of touch, feel, comfort and visibility, so the material should meet the requirements of non-reflective surface, no peculiar smell, no substances that make the car glass obscure, easy removal of surface dirt, and good flame retardancy and so on.

People have higher and higher requirements for environmental protection and their own health, and plastic parts have also become a major part of automotive VOC detection. When the toxic and volatile gases used in automotive interior materials reach a certain concentration, people will experience headaches, nausea, and even convulsions within a short period of time, and will damage the liver, kidneys, brain and nervous system, posing a serious threat to human health. Environmentally friendly, healthy, and safe interior space has always been an eternal topic in the automotive industry. To fundamentally improve the air pollution in the car, OEMs need to control from the source-strictly select environmentally friendly plastic particles to make auto parts.

In 2018, Qingdao Yishibao developed a low-odor, low-VOC modified PP special material for car interiors in response to the problem of air pollution in the car. The material has the characteristics of balanced mechanical properties, excellent processing performance, high heat resistance, low odor (PP material odor ≤ 3), low emission, etc., which can effectively reduce the content of harmful substances in the car. Modified PP special materials for automotive interiors have become the best choice for automotive interior plastics that care about the health of users.


Advantages of low-odor, low-VOC automotive interior pp modified materials:

1、Select high-quality raw materials, low content of small molecules and low VOC content.

2、Use preferred fillers and additives to inhibit material degradation and achieve the purpose of reducing VOC content.

3、Use a specific process: vacuum devolatilization (multi-level vacuum and vacuum degree requirements), high temperature thermal desorption
