Application
*TRUELICHT 5500 is a monomer carbodiimide type hydrolysis stabilizer for polyester polyurethanes(PU and TPU) and biodegradable resins,like PLA、PBAT、PPC、PHAs.
*TRUELICHT 5500 will significantly improve hydrolysis stability and shelf life of substance in high temperature and humidity environment.
*Suggested dosage in PU resins is 1.0 phr of polyester polyol, 1.0phr-2.0phr in adhesives.
