What are DOT or UN regulations affecting permeation?
A. The US Department of Transportation requirement for products transported over US highways is that chemicals and solvents lose less than 2% weight per year per package. This serves to protect warehouse and shipping personnel from excessive fume exposure and to protect the consumer from underweight packaging. Note that for certain hazardous materials the permissible weight loss is only 0.5% per year per package! Fluorination can often boost HDPE container performance enough to help you meet these targets. Over 20,000 of our customers worldwide have been able to maintain use of impact resistant HDPE packaging and avoid switching to less desirable glass or metal containers or to more expensive barrier resin or barrier coated containers.
