EVOH

Ethylene vinyl alcohol copolymer

EVOH gives the best oxygen and aroma barrier among thermoplastics; it is used as a thin middle layer in multilayer packaging, wrapped by polyethylene or polypropylene to protect it from moisture. Lower ethylene content raises the barrier and lowers processability. Uses include food packaging, fuel tanks and underfloor-heating pipe.

Overview

EVOH is the standard grade of the EVOH family in the general-purpose plastics group. It is used in applications such as multilayer food packaging and lidding, automotive fuel-tank barrier layer, oxygen-barrier pex and ppr pipe. The grade with the right flow for injection, extrusion or another process is specified in the quotation together with your quantity and colour; TDS and SDS are sent with the quotation.
