This plastic is remarkably strong and has good chemical resistance. All sizes have easy to read graduations. Each vessel has ribs for stacking. Their square design also saves shelf space.
Polymethylpenetene plastic is clear like glass.
It will resist breaking after frequent impacts. The chemical resistance is outstanding except for very strong oxidizing agents. Prolonged exposure to hydrocarbons will cause the plastic to cloud. These are an excellent choice. These bottles are made from high density polyethylene.
