Non-halogenated FRs for glass-reinforced nylons.Two developmental non-halogenated flame retardants are the first of a new generation of FR additives for glass-reinforced nylon 6 and 66 electrical/electronic components. Developed by Clariant Corp.'s Pigments & Additives Div., Coventry, R.I., Exolit OP 1311 and 1312 are based on metal phosphinates and synergists suitable for glass-reinforced compounds. Exolit OP 1312 is a specially stabilized system for injection molding injection molding n. A manufacturing process for forming objects, as of plastic or metal, by heating the molding material to a fluid state and injecting it into a mold. nylon 66 into complex shapes that may require high temperatures and injection speeds. Both are said to give a Comparative Tracking Index The Comparative Tracking Index or CTI is used to measure the electrical breakdown (tracking) properties of an insulating material. To measure the tracking, 50 drops of 0. (CTI (Computer Telephone Integration) Combining data with voice systems in order to enhance telephone services. For example, automatic number identification (ANI) allows a caller's records to be retrieved from the database while the call is routed to the appropriate party. ) of 600 V and low compound density. They reportedly have little or no adverse affect on mechanical properties, unlike most halogenated halogenated pertaining to a substance to which a halogen is added. halogenated salicylanilides see rafoxanide, clioxanide. FRs. Amounts needed to achieve UL 94V-0 or a Glow Wire Flammability Index (GWFI) of 960 C are said to be well below those for other FRs except for red phosphorus (Chem.) an allotropic modification of phosphorus, obtained as a dark red powder by heating ordinary phosphorus in closed vessels. It is not poisonous, is not phosphorescent, and is only moderately active chemically. . They also reportedly allow easy dispersion and good flow and colorability. Pilot quantities are currently available. A large-scale plant in Germany will be brought on line at the end of 2004. Tel: (401.) 823-2000, www.clariant.com |
