The automotive industry is setting increasingly stringent requirements for materials: interior parts require excellent scratch resistance, low‑VOC and low‑odor performance; exterior parts demand good weather resistance and impact resistance; components around engines need long‑term resistance to high‑temperature, high‑humidity and oil‑contaminated environments. Meanwhile, the lightweight trend fuels the large‑scale adoption of modified polypropylene and glass‑fiber‑reinforced nylon, which also brings new challenges including surface scratching, glass‑fiber blooming and insufficient processing flowability. Handian New Materials delivers one‑stop additive solutions for the automotive industry. AS‑series scratch‑resistant agents can significantly enhance scratch resistance and stress‑whitening resistance of polypropylene interior parts. HD‑6000 anti‑glass‑fiber‑blooming masterbatch effectively solves glass‑fiber blooming on glass‑fiber‑reinforced nylon products and improves surface appearance quality. High‑molecular‑weight silicone masterbatch and GTF‑650 silicone powder optimize processing flowability, mold‑release property and surface tactility of finished products, while boosting wear resistance. KSJ‑series anti‑hydrolysis agents ensure long‑term reliability for polyester‑based engine‑surrounding components under high‑temperature and high‑humidity conditions. Main applicable products: AS‑series, HD‑6000, TM‑500G, GTF‑650, KSJ‑series

Chemical fiber spinning processes set harsh requirements for additives: additives should withstand high‑temperature processing without decomposition, exert no negative influence on fiber color and dyeing performance, and realize high dispersion of inorganic powders in color masterbatches so as to avoid filament breakage and filter blockage. Polyester fibers used in hot‑humid environments also need excellent hydrolysis resistance to secure long service life of end‑products. Additives from Handian New Materials cover multiple procedures in the textile industry. HD‑series inorganic‑powder dispersants are used in spinning color masterbatches to efficiently disperse fillers such as carbon black, titanium dioxide and calcium carbonate, improving spinnability and color uniformity. KSJ‑series anti‑hydrolysis agents enhance durability of polyester fibers in hot‑humid conditions. High‑molecular‑weight silicone masterbatch and silicone powder boost flowability and inorganic‑powder dispersion during masterbatch preparation.
