Basic Features
The product reacts with the decomposition product carboxylic acid or water to produce urea-based compounds that do not have any negative effect on the stability of the parent material. At the same time, it can also prevent the molecular weight of the polymer from decreasing during processing, and under the stabilization of the product, the service life of the polymer can be extended. It can improve the hydrolysis resistance of PU products and PU adhesives, long-term use in humid environments, high elastic elongation and strength retention, no embrittlement, not easy to crack, good appearance, widely used in various ester and amide groups. Polymeric materials, lubricating greases and organic liquids, especially at higher process temperatures. It can remove acid and water and prevent autocatalytic degradation. Improve the service life of the polymer, especially the anti-hydrolysis stability performance under the conditions of high temperature and humidity and acid and alkali media. It has the advantages of small dosage, low toxicity and high hydrolysis resistance.
Scope of application
It is suitable for improving the anti-hydrolysis stability and anti-aging performance of materials such as PET, PBT, PU, PU rubber, TPU, CPU, TPEE, PA6, PA66, EVA, PLA, PBS, PBAT, PHB and adhesives.
Recommendations
After mixing the product with resin and other modifiers, it is extruded and granulated by an extruder. The addition ratio of 0.3-5% can significantly improve the hydrolysis resistance of the product.
Packaging and storage: 25KG/bag; sealed and stored in a dry, cool, dark place.
Safety Instructions: Do not eat, drink or smoke when using this product, and wash your hands thoroughly after work.
