Product Structure


Typical Application Methods

Bio-SAH™372N is a polymerized carbodiimide that can be widely used in mixed modification materials such as TPU, PET, PBT, PBAT, PLA, PHA, PBS, PTT, and PA. It is a high-temperature resistant and long-lasting hydrolysis resistant stabilizer.

Application Methods
PLA/PBAT The addition amount is 0.6-1.5phr to the resin, can effectively reduce acid value and improve hydrolysis resistance.
TPEE The addition amount is 1.0-3.0phr, the resulting elastomer product can be used for a long time in high temperature and humid environments and maintain good mechanical properties.
PET/PBT Industrial rubber  filament The addition amount is 1.0-3.0phr, can extend the hydrolysis resistance of the rubber  filament by 3 to 8 times.

Why Choose KSTO Anti-hydrolysis Additives ?

Carbodiimide anti-hydrolysis agents can provide excellent hydrolysis resistance protection for polymers containing ester, urethane and amide groups, maintain the initial mechanical properties of products, prolong the service life of products, and make your polymer products widely used in harsh environments such as high temperature and humidity.

Compared with the traditional thiourea process, our company takes the lead in using isocyanate condensation process to produce carbodiimide hydrolysis resistant products, which have the characteristics of high purity, high activity, no smell, no discoloration and no sulfur residue.

KSTO has been committed to providing our customers with high-quality, cost-effective carbodiimide anti-hydrolysis additives.
