Further information about HDPE Mortars

Someone recently raised the question as to whether there could be potential problems with high density polyethylene (HDPE) mortars from contact with detergents and from exposure to sunlight. This article was drafted in response to a request to address those concerns and also to present an update on the status of acceptance of HDPE mortars by display companies and regulatory agencies.

With respect to HDPE and contact with detergents, it was suggested that some detergents may be capable of attacking HDPE. I knew of no such detergent and after checking with an expert in the field, Mr. David Tebeau of AFD, Inc., I still do not know of any such detergents. I do not feel there is any reason to avoid contact between HDPE and detergents; in fact most liquid detergents are packaged in polyethylene containers.
