Nylon 6 nanocomposites: tough + stiff + barrier.Nylon Corp. of America (Nycoa), Manchester, N.H., has two new nylon 6 nanocomposites that reportedly provide novel combinations of toughness, stiffness, and barrier properties. Nycoa's nanoTuff is for stiff structural components while nanoSeal meets new, stricter emission regulations for fuel tanks in California. Nycoa's batch polymerization polymerization Any process in which monomers combine chemically to produce a polymer. The monomer molecules—which in the polymer usually number from at least 100 to many thousands—may or may not all be the same. process incorporates surface-modified nanoclay particles into a high-meltstrength nylon 6 in the reactor. The clay is said to bond to the polymer chains. Nycoa says the result is 175% higher stiffness and 116% higher HDT HDT Heat Deflection Temperature (plastics) HDT High Dose Therapy HDT Heatpipe Direct Touch (Xigmatek) HDT Heat Distortion Temperature (plastics) HDT Henry David Thoreau than neat nylon 6. Injection moldable nanoTuff also boasts 70% higher flexural flexural pertaining to the flexure of a joint. flexural deformity fixation of joints in flexion. In the newborn called contracted calves or foals. modulus than standard supertough nylon. It reportedly meets the coldweather impact needs of sporting goods such as skate blade holders and snowboard and ski-boot bindings. Nanoclay platelets in nanoSeal barrier compound for molding or extrusion create a tortuous path for liquid or vapor to penetrate. Fuel permeation is said to be reduced up to 97% vs. neat HDPE HDPE abbr. high-density polyethylene and 40% vs. neat nylon 6. It is used in small fuel tanks and as a barrier layer in film and hose for automotive, marine, and refrigerant re·frig·er·ant adj. 1. Cooling or freezing; refrigerating. 2. Reducing fever. n. 1. A substance, such as air, ammonia, water, or carbon dioxide, used to provide cooling either as the working substance of uses. It is also being considered for barrier packaging because of its low oxygen and moisture transmission. Tel: (800) 851-2001 * PTDirect: 454DF [ILLUSTRATION OMITTED] |
