Basic features
This product reacts with the decomposition product carboxylic acid or water to generate urea-based compounds that do not have any negative effects 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. Under the stabilizing effect of this product, the service life of the polymer can be extended. It can improve the hydrolysis resistance ofPU products and PU glue. It can be used in humid environments for a long time. It has high elastic elongation and strength retention, is not brittle, not easy to crack, and maintains good appearance. It is widely used in various types of esters and Polymer materials, lubricating greases and organic liquids with amide groups, especially at higher process temperatures. It can remove acid and water and prevent autocatalytic degradation. Improve the service life of the polymer, especially its hydrolysis resistance and stability under conditions such as high temperature, humidity, acid and alkali media. It has the advantages of small addition amount, low toxicity, and high product resistance to hydrolysis.

Application scope
Suitable for liftingPET, PBT, PU, ​​PU rubber, TPU, CPU, TPEE, PA6, PA66, EVA, PLA, PBS, PBAT, PHBThe hydrolysis resistance and anti-aging properties of materials such as adhesives and adhesives.

Usage suggestions
Mix the product with resin and other modifying additives and then extrude and granulate it by an extruder. The addition ratio is between 0.3-5% and it can be significantly improved. Product hydrolysis resistance.

Packaging and Storage : 25KG/bag; sealed and stored in a dry, cool and dark place.

Safety Guidance Do not eat, drink or smoke when using this product. Wash hands thoroughly after working.
