Instructions for use:
The anti hydrolysis agent FT-9188 is a polycarbodiimide formed by condensation under specific reactions, belonging to the sterically hindered aromatic anti hydrolysis stabilizer; It reacts with water or hydrolysis product hydroxy acid, and has strong reactivity with hydroxy acid and sulfonic acid at high temperatures, thereby eliminating hydroxyl groups produced by ester groups, urea groups, and other easily hydrolyzable groups in polymer materials, resulting in chain breaking and reconnection effects, preventing the degradation process and occurrence of self catalytic hydrolysis, improving and extending the service life of the polymer, and reducing the acid value of the material; Especially in harsh usage environments such as high temperature, high humidity, and acid-base environments, the product's resistance to hydrolysis and hydrolysis stability can be improved.
Application scope:
Especially suitable for polyester (PET, PBT, TPEE), such as fishing nets and chemical fibers; Nylon polyamide (PA6, PA66, PA11, PA12); It is also suitable for polyurethane (PU, TPU) products, EVA, as well as easily hydrolyzable materials such as adhesives and resins.
Suggested dosage: PET and PA nylon: 0.5-1.5%;
PU and TPU: 0.7-1.5%;
EVA: 2-3%;
Glue, ink, resin: 2-3%.
Packaging: 25KG/packaging; Paper barrel packaging with PE inner bag inside.
