Examination of the relationship between ESCR and the molecular structure of HDPE blow molding grades

The environmental stress crack resistance (ESCR) is an important property of HDPE (high density polyethylene) products especially of blow molded products.

The ESCR result informs us about the prediction of the longterm behaviour of the products, how suitable is HDPE for storage of several final products without cracking and which basic material is adaptable for the product.
