PVC 

National Pipe & Plastics' PVC Pipe and Conduit compounds are processed with rutile titanium dioxide (TiO2) which serves as an ultraviolet inhibitor. The level of TiO2 proportioned into these compounds is sufficient to protect the product against the effects of ultraviolet degradation for a minimum of two years to accommodate storage, transportation and handling, prior to installation.

HDPE

National Pipe & Plastics' HDPE PE 3608 Polyethylene Pipe products are processed from plastic compounds that are properly stabilized for conditions of ultraviolet radiation and weather ability.  Our compound stabilization package is formulated with a minimum of 2 percent finely dispersed carbon black.  It has been determined that this percentage of well-dispersed very fine particle carbon black is considered sufficient to protect out Polyethylene Pipe for continuous outdoor service.
