The liner, (or contact surface), is made of a clear, chemically inert, low-density polyethylene (LDPE) material. The outer shell is manufactured from high-purity ethylene vinyl acetate (EVA), which gives superior flexibility and clarity along with good burst strength.
While Chem-A-Line and Chem-A-Line XL are made of the same base materials, Chem-A-Line XL is gamma-irradiated, which cross-links the material for even greater thermal, chemical and mechanical performance. Chem-A-Line is certified, and it can resist attack from most solvents. It is plasticizer free and REACH compliant. Chem-A-Line has excellent barrier characteristics along with very low gas and liquid permeability. It works well with compression and other types of push-on fittings.
Chem-A-Line meets the most stringent criteria for bio-pha maceutical product transfer. They are also widely used in the water and printing industries.
