[Performance and application]
1.Soluble in ethanol and other organic solvents, stable to heat.
2.Polyether 303, 310 and 330 can be used to produce polyurethane elastomer, which can enhance hardness; It can also be used as an intermediate in chemical synthesis.
3.Polyether 310 compounded with polyoxypropylene glycol can be used to make polyurethane adhesive, and can be used in waterproof materials, rubber, pavement materials and other fields.
4.Polyether 330 can be used to prepare soft foam polyurethane plastics. Polyurethane paint and coating are prepared by compounding with sorbitol polyether polyol, with bright and bright surface, strong color fastness and no yellowing. It can also be used as an intermediate in chemical synthesis.
5.Polyether 330 can be used as defoamer in pharmaceutical, monosodium glutamate, paint and sugar production. It has the effect of eliminating foam and inhibiting foaming.
