Additive Boosts Flow And Abrasion Resistance.A new processing aid and internal lubricant is said to improve the abrasion resistance of both thermoplastics and thermosets thermosets, materials that can not be softened on heating. In thermosetting polymers, the polymer chains are joined (or cross-linked) by intermolecular bonding. Thermosets are usually supplied as partially polymerized or as monomer-polymer mixtures. . Fluoroguard from DuPont Performance Lubricants, Wilmington, Del., is a colorless, odorless o·dor·less adj. Having no odor. o  dor·less·ly adv.o , and chemically inert additive based on a fluorinated fluorinated material to which a fluoride has been added, e.g. water for human consumption treated as a prophylaxis against tooth decay. synthetic oil. It is aimed at gears, bushings, automotive weatherstripping, footwear, o-rings, seals, and films. Thermally stable to 572 F, it reportedly can be used in most polymers. It is said to improve melt flow and mold release, cut machine power consumption, boost extrusion rates, and reduce die buildup. DuPont says it may eliminate the need for silicone or PTFE PTFE polytetrafluoroethylene. . |
