Vulcanized TPEs.

Vulcanized thermoplastic elastomers (TPVs) are said to feature the company's proprietary cure technology. Designated NexPrene 9500 SHF (super high flow) materials, TPVs in the series are said to exhibit viscosities that are up to 60% lower than those of conventional thermoplastic elastomers. There are currently six grades in the 9500 SHF Series, ranging in hardness from 55 to 85 durometer A. Each material has been developed to offer injection molders higher melt-flow rates, shorter fill times, longer flow paths and lower injection pressures. These products are non-hygroscopic, so they require no pre-drying prior to processing. The SHF grades are said to flow so much better that injection molding cycles can be as much as 15% shorter than with traditional vulcanized thermoplastic elastomers. Initial evaluations of molded parts are said to indicate that surface aesthetics attainable using NexPrene 9500 SHF materials are superior to those achieved using conventional thermoplastic elastomers. Materials in the NexPrene 9500 SHF series are said to be very stable. (Solvay Engineered Polymers)
