Application

Polytetrahydrofuran, as an important chemical raw material, is mainly used in the field of chemical fiber for the preparation of spandex, and in the field of non-fiber for the preparation of elastomers, adhesives, coatings, sealants and other fields. The polyurethane products prepared with it are wear-resistant, chemical corrosion resistant, and have good flexibility and resilience

Used for the production of TPU, CPU, PU resin, PU paste, polyurethane elastomer, etc

PTMEG is one of the important raw materials for the production of spandex and polyamino acid elastomer. It is used as the soft segment in ammonia ester and can provide good hydrolysis resistance, low temperature resistance and dynamic properties of polyurethane products. It can also be used as the main raw material for elastomer products, synthetic leather resins, elastic fibers (spandex).
