GB/T 16576-2010Plastics - Trihydroxy polyether polyols (English PDF)

1 Scope

This standard specifies the trihydroxy polyether polyols 330,330E, 330H, 348H, 360H, 330X, 303,310,337E, 370H to

Requirements, test methods, inspection rules and signs, packaging, transportation, storage and so on.

This standard applies to the triol as the initiator in the catalyst with propylene oxide, (or) with propylene oxide, ethylene oxide ring-opening polymerization

The resulting polyether polyol 330,330E, 330H, 348H, 360H, 330X, 303,310,337E, 370H.
