Super-tough material

Initial materials of this super-tough type were blends of nylon 66 with an ionomer resin (see Chapter 11). More recent materials are understood to be blends of nylon 66 with a modified ethylene-propylene-diene terpolymer rubber (EPDM rubber—also see Chapter 11). One such modification involves treatment of the rubber with maleic anhydride, this reacting by a Diels—Alder or other... 

The coating of soft, scratchable materials with a super-tough diamond layer should improve many types of consumer products in the near future. 

Theoretically, just a few years ago. It would have been Impossible to achieve super toughness In a highly crystalline material such as acetal homopolymer. That theory was disproved with the discovery of super tough Delrln lOOST. With continued high quality research effort the future will hold even more technological breakthrou s. 

The nylon 6,6 family has produced reviews on Zytel 5T, a new super tough system and its applications, and Maranyl nylon 6,6 range of materials. Precision moulding from Vespel polyamides and aromatic polyamides are discussed together with electrical and engineering applications. ...

Only the oil palm industry in Malaysia produces more than a million tones of empty fruit bunches annually as a by-product [48]. Oil palm fiber is anticipated to be a promising raw material due to its toughness [49]. Hasibuan and Daud [48] investigated the effect of super heated steam drying on the surface morphology, color and tensile properties of oil palm empty fruit bunch fibers. John et al. [49] developed oil palm... 

Another interesting development in the field of crystalline polymer blends was initiated by the Toyota Motor Corporation, which recently introduced a super-olefin polymer. This material was designed on a lamellar level (on a nanometer scale), and it has been speculated that this material is a blend of low-molecular-weight poly (propylene)(PP) with a new olefinic copolymer. This material, which has excellent hardness and toughness, as well as good flow properties, was designed to replace the expensive reaction injection molding (RIM) polyurethane [3].
