Isoplast engineering thermoplastic polyurethane resins of Dow [15] combine the toughness and dimensional stability of amorphous resins with the superior performance and chemical resistance associated with semicrystalline resins. Isoplast is available in impact-modified, clear and glass-reinforced resins, with a range of options to meet the most demanding applications. Table 15 gives descriptions and applications of Isoplast TPE-U products. 

The Hquid monomers are suitable for bulk polymerization processes. The reaction can be conducted in a mold (casting, reaction injection mol ding), continuously on a conveyor (block and panel foam production), or in an extmder (thermoplastic polyurethane elastomers and engineering thermoplastics). Also, spraying of the monomers onto the surface of suitable substrates provides insulation barriers or cross-linked coatings. 

Polyurethane engineering thermoplastics are also manufactured from MDI and short-chain glycols (49). These polymers were introduced by Upjohn/Dow under the trade name Isoplast. The glycols used are 1,6-hexanediol and cyclohexanedimethanol. 1,4-Butanediol is too volatile at the high processing temperatures used in the reaction extmsion process. Blends of engineering thermoplastics with TPU are also finding uses in many appHcations...

Polyacetal polyphenylene oxide are widely used as engineering thermoplastics, and epoxy resins are used in adhesive and casting application. The main uses of poly(ethylene oxide) and poly(propylene oxide) are as macroglycols in the production of polyurethanes. Polysulfone is one of the high-temperature-resistant engineering plastics. 

Polyurethane adhesives are typically more flexible than epoxies, with good shear and high peel strengths on metals and engineering thermoplastics. These types of adhesives are particularly well-suited for joining substrates with dissimilar coefficients of thermal expansion and for securing various types of inserts in composite panels.
