INVISTA’s TERATE® polyols are aromatic polyester polyols used in polyisocyanurate and polyurethane foams, as well as a variety of CASE (Cast, Adhesive, Sealant and Elastomer) applications. TERATE® polyols are used in rigid polyurethane foam systems for appliance, bunstock, roof and wall boardstock, spray foams and insulated composite sandwich panel applications; in addition to polyurethane coatings for polymer binders and resin systems.
INVISTA's TERRIN™ polyols can be used in lieu of or in combination with conventional polyether or polyester polyols to formulate a variety of polyurethane products designed to be soft and flexible—or hard and stiff. Versatile, aliphatic TERRIN™ polyols can be used in applications ranging from viscoelastic foam to spray coatings and adhesives to elastomeric resins.
TERATHANE® polyether glycol
INVISTA’s TERATHANE® polyether glycol, also known as PTMEG, is a premium intermediate used as a soft-segment building block in high-performance polyurethanes, polyesters and other polymers. Typical end-uses for TERATHANE® PTMEG include spandex fiber such as LYCRA® fiber; solid elastomers, including skate wheels, belts and rollers; and flexible adhesives and coatings.
Butanediol (1.4 BDO) is used to make a variety of esters, including monomeric plasticizers. It is also used in the engineering of plastic polybutylene terephthalate (PBT) and polyester glycols with low molecular weight.
BDO is used in the hard segments of polyurethanes, particularly those made with modified dipole interaction (MDI). Because BDO produces a good balance between hardness and low temperature flexibility, it is used a cross linker and a chain extender. BDO is also found in the soft segments of polyurethanes, acting as polyesterdiols, such as polybutylene adipate glycol. When BDO reacts with various dibasic acids, such as adipic and sebacic acid, polyester glycols in polyurethanes and are formed.
