☑ Polyester, polyamide, EVA and polyurethane, Soluble in organic solvents            ☑ It is an effective additive to prevent polymer degradation due to an exposure to humidity and acids.it helps maintain the molar mass and, thus, mechanical properties as well as melt strength of our bio-based polyester in spite of detrimental processing steps;

☑ Improve the viscosity drop, yellowing and cracking of plastics due to hydrolysis

☑ It’s especially suitable for bio-based polyesters. it’s also an efficient antihydrolysis agent for polyester-polyurethane elasomers also widely used in other thermoplastic resins such as PLA,PET/PBT, elastomers, adhesives and coating systems.as the antihydrolysis agent for PET,PBT,PA,CO-PET, PU, TPU,CPU,TPEE,EVA,PLA,PHA,PBS,PTT,it can extend the usage life of these polymers under hot and high humid conditions.
☑ It is used in matting adhesives;

☑ it is used in the production of polyglycolic acid (PGA) which is intended to be used for : i) layers behind polyesters such as polyethylene terephthalate (PET) or polylactic acid (PLA) and other low diffusivity materials not in direct contact with foodstuffs, ii) blends of PGA with PET, PLA or other low diffusivity materials in direct contact with foodstuffs.

☑ It is used as auxiliary in pharmaceutical or agrochemical formulation.
