The technical data on this page represents only average values and not minimum values.  Safety factors must be added into the design.

 

Chemical Resistance

High-Density Polyethylene has a high resistance to most acids and chemicals.  Plastic Lumber has a high tolerance to exposure by most substances.

 

Ultraviolet Weathering

An ultraviolet stabilizer is added at the time of manufacture to help protect against ultraviolet degradation of the plastic surface in exterior applications.
