PTMEG-250 for flexible TPU adhesives with high tensile strength

Description
Polytetramethylene etherglycol, also known as polytetrahydrofuran, referred to as PTMEG or PTG, is a linear polyether glycol with hydroxyl groups at both ends of the molecule, which is formed by ring-opening polymerization of tetrahydrofuran.

Application

PTMEG has excellent reactivity and is widely used in elastomer block polymers, showing excellent low-temperature elasticity, microbial resistance and hydrolysis stability, including polyurethane fiber (spandex), polyurethane elastomer, synthetic Leather, coating, adhesive, sealant, polyester elastomer and polyamide elastomer.

Technical Specification

Water	ppm	≤300
Color	APHA	≤50

Package

200kg / drum or ISO tank for packaging and transportation

Shelf Life

Shelf life of PTMEG is approximate 2 years, under condition that the product is stored in unopened, tightly sealed original container at no greater than 90℃ and is not contacted with air under a dry nitrogen blanket.

Shelf life is only guidance and is not a guarantee because there are various possibilities in site of end users to affect the quality of PTMEG.
