water absorption

Let us learn about water absorption

The quantity of water absorbed by a composite material, when immersed in water occurs for a stipulated period of time. The ratio of weighted water absorbed by a material so to the weight of the dry materials. All organic polymeric materials will fascinate moisture to some extent resulting in swelling, leaching, dissolving, plasticizing and/or hydrolyzing, events which can result in discoloration, embitterment, loss of mechanical and electrical properties, lower resistance to heat and weathering and stress cracking

Water absorption is used to determine the quantity of water absorbed under specified conditions. Factors affecting water absorption consist: type of plastic, additives used, temperature & length of exposure. The data sheds light on the implementation of the materials in water or humid environments.
