SU Chemistry Dept develops new cardo groups

Rajkot, Apr 26 (UNI) Dr P H Parsania and his team under the polymer group of Department of Chemistry of Saurashtra University has developed new cardo groups containing phenolic, epoxy, polyurethane, polyester polyor resins for surface coating application on glass, wood steel, aluminum, tin, copper etc and claimed to be obtained promising results in humid, acidic and saline environments.

These resin are also found to be good for water proofing, Dr Parsania said here in a release.

These resins are also used in combination with glass and jute fibers and also with agricultural wastes such as wheat, rice, wood, bamboo and sugarcane husks for the development of biocomposites, the release said.

These composites possess good mechanical and electrical properties indicating their usefulness in low cost housing units, furniture, marine and electrical industries, the release added.

The potential and future benefits of polymers to mankind are unlimited.

In India natutral fibers such as jute, coir, sisal, pineapple, ramie, bamboo, and banana are available in abundant, the release said.

Natural fibers bases composites are well suited as wood susbstitutes for housing and construction applications. They prevent depletion of forest resources and ensure good returns to the cultivators.

During natural calamities such as earthquakes, floods and cyclones, light weight building materials are very important in saving life and house hold commodities.
