High bio-content polymer.


A polymer with a high bio-content uses castor oil castor oil, yellowish oil obtained from the seed of the castor bean. The oil content of the seeds varies from about 20% to 50%. After the hulls are removed the seeds are cold-pressed.  extracted from the seeds of the castor bean castor bean, bean produced by Ricinus communis, a plant of the spurge family, widely cultivated as an ornamental. Moles die when they eat the roots. It has long been used as an ordeal poison in parts of Africa. . The bio-based polymer is said to feature superior flexibility that can withstand repeated bending. Concern over carbon dioxide carbon dioxide, chemical compound, CO2, a colorless, odorless, tasteless gas that is about one and one-half times as dense as air under ordinary conditions of temperature and pressure.  emissions has raised interest in the use of bio-based polymers, according to the company.
