Technology blocks harmful light wavelengths
Harvel Plastics, Inc., has launched EnviroKingUV, a clear PVC piping that is suitable for exposure to sunlight. Unique ultraviolet (UV)-blocking technology reduces harmful UV light wavelengths from penetrating the plastic while allowing beneficial wavelengths through. EnviroKingUV offers a solution for photobioreactor use and other outdoor applications exposed to sunlight where transparency is required.
A new website, EnviroKingUV.com, provides details on its physical properties, applications, specifications and installation parameters.
It is produced from a unique, rigid, transparent PVC compound per ASTM D1784. The pipe is produced to IPS dimensions from this material. Specialty ThinWall dimensions have been optimized in a variety of diameters that improve light transmission while maintaining product rigidity. The pipe is also available in Schedule 40 dimensions. EnviroKingUV is patent pending.
"EnviroKingUV was developed to meet the demands of innovative technologies related to the renewable energy market and other emerging green industries," said Bill Weaver, Harvel's director of technical services. "It's ideally suited for a wide range of outdoor applications including containment vessels for the commercialization of micro algae (photobioreactors), biofuel processing, carbon capture and recycling, process R&D, filtration and sight glass."
