New metallocene TPE tried first as modifier.A new series of propylene-based TP elastomers is expected to find use in a wide variety of applications, though their initial target is as modifiers for polyolefins and other resins resins, n.pl complex, insoluble, sticky substances secreted by plants. Used as astringents, antimicrobials, and antiinflammatories, and are burned as incense. Can cause oral ulcers and epidermal irritations. in automotive and electrical appliance A stand-alone hardware device or software environment dedicated to a specific task.

The Tafmer XM from Japan's Mitsui Chemicals (represented here by Mitsui Plastics, Inc., White Plains, N.Y.), is produced with the company's proprietary metallocene catalyst Metallocene catalyst A transition-metal atom sandwiched between ring structures having a well-defined single catalytic site and well-understood molecular structure used to produce uniform polyolefins with unique structures and physical properties. technology. Commercial production of the new soft materials started last month. XM-series elastomers boast higher performance than Tafmer resin resin, any of a class of amorphous solids or semisolids. Resins are found in nature and are chiefly of vegetable origin. They are typically light yellow to dark brown in color; tasteless; odorless or faintly aromatic; translucent or transparent; brittle, fracturing modifiers produced with Ziegler catalysts. For example, when blended with PP for the heat-seal layer of PP films, XM elastomers have been shown to allow sealing at 20[degrees]C (36[degrees]F) lower temperature than previous Tafmer grades. Their excellent antiblocking properties are said to prevent film from sticking together during storage and transportation. Tel: (914)251-237 * PT Direct: 473DD |
