Development and Application of Low Odor, Low VOC Thermoplastic Composite Materials

Polymer materials (plastics) are widely used in various fields of the national economy and people's lives due to their low density, corrosion resistance, and ease of processing. Throughout the entire lifecycle of plastics, volatile organic compounds (VOCs) and odors are produced, especially during plastic modification where new VOCs are often generated due to the introduction of additives and processing degradation. In the past few decades, many researchers have conducted extensive research on the VOC composition, low VOC treatment technology, and spray free treatment technology of plastics, achieving some good results, but still unable to meet people's requirements.  

Chongqing Kejufu New Materials Co., Ltd. focuses on low odor and low VOC in plastic processing. Through self-made extrusion processing equipment and the use of self created multi-stage directional extraction and multi-stage adsorption methods, the company fully utilizes the good synergistic effect of independently developed high-efficiency adsorbents and environmentally friendly extractants in the preparation process. It has independent intellectual property rights, obtained 11 invention patents, and obtained a set of technologies to improve plastic odor and VOC, and prepared multifunctional composite materials with low odor and low VOC. Among them, polyolefin materials: odor ≤ 2.5 level, TVOC≤3000μg.m-3； PC/ABS material: odor ≤ 3.0 level, TVOC≤3000μg.m-3； There are other thermoplastic composite materials with low odor and low VOC, all of which meet the EU ROHS standard requirements.

The low odor, low VOC thermoplastic composite materials developed and produced by Kejufu Company are widely used in automotive interior, seats, instruments, air conditioning and other components.
