March 12, 2025 – Pritech (002324) has recently announced that the company has successfully secured authorization for a national invention patent, titled “Innovative Composite Material and Its Manufacturing Process for Low-Gloss, Soft-Touch Seamless Airbag Dashboards.” The patent was officially granted on March 11, 2025. According to the patent abstract, this invention is at the forefront of polypropylene composite material technology, specifically revealing a novel composite material and its preparation method tailored for automotive dashboards. This composite not only boasts an outstanding appearance and superior performance but also features a low-gloss finish and a soft touch. Its unique formula incorporates a polypropylene matrix, natural plant fiber reinforcements, polysiloxane modifiers, crosslinking agent masterbatches, compatibilizers, and color pigments, among other additives.
Insights from the Color Masterbatch Industry Network reveal that the core of this invention lies in the ingenious incorporation of polydimethylsiloxane, effectively addressing the brittleness of natural plant fiber-reinforced polypropylene in low-temperature environments while imparting the material with low-gloss and soft-touch characteristics. This innovation not only meets the high aesthetic quality requirements of automotive components but also holds promise for replacing traditional leather-covered materials by reducing production costs, offering a more environmentally friendly and economical solution for the automotive industry.
