| The main uses for TERATHANE® PTMEG involve the reaction of the hydroxyl groups with either organic acids or isocyanates. Thus, these glycols become segments or building blocks in a variety of modern polymers, chiefly in polyurethanes but also in copolyesters and polyamides. See the page Worldwide Applications which illustrates the broad uses of TERATHANE® PTMEG. Also visit the Home Pages of some TERATHANE® PTMEG customers via the links down on this page and see their applications ... |

| Reaction with diisocyanates permits the use of TERATHANE® PTMEG as soft segments in polyurethanes. If the diisocyanate is TDI ( toluene diisocyanate), amines such as MBCA (4,4-methylene-bis 2-chloroaniline), formerly known as the trademarked MOCA, are favored as chain extenders or curatives. MBCA is a possible carcinogene and subject of OSHA activity. If MDI (diphenyl methane 4,4-diisocyanate) as diisocyanate is used, then 1,4 butanediol is the favored chain extender. |

TERATHANE® PTMEG gives urethanes with superb resistance to low temperatures and hydrolysis. They also have excellent dynamic properties including resilience. For example, TERATHANE® 2000 gives a higher resilience than any other commercially available soft segment in many polyurethane formulations. TERATHANE® PTMEG itself and its prepolymers have low viscosities, leading to easier handling. The prepolymers have long shelf-lives.
