Abstract (English):
The present study examined the application of ethylene vinyl alcohol copolymer (EVOH) as additive to the polyethylene matrix of wood-plastic composites (WPC). Composite samples were prepared with softwood sawdust and mixtures of EVOH with polyethylene in various proportions. The hardness, tensile strength, elastic modulus, flexural strength, toughness, tensile elongation, and water absorption of this samples were measured. Analysis of the properties of obtained composites showed that EVOH additive to the polyethylene matrix WPC increases toughness, flexural strength and reducing water absorption.
