(which are essential for life). Most plastics are based on ethyl-ene gas derived from crude oil. A simple example of a basic plastic is PE, therepeating units of which are based on ethylene monomer. Polymeric materials fromnatural sources such as shellac, amber and natural rubber have been...

Therefore, in addition to naturally derived biopolymers, there are also petroleum-based biodegradable biopolymers. Natural Biopolymer Natural biopolymers are natural polymers produced by living organisms; in other words, they are polymeric biomolecules derived from cells or extracellular material. Biopolymers ...
What are the main differences between silicone and Silastic? Silicone is a broad category of synthetic polymers, while Silastic is a specific type of highly durable silicone rubber. 7 What are the advantages of Silastic over other materials? Silastic offers enhanced durability, chemical resistance, ...

They are widely used in the manufacture of flexible and rigid foams, fibers, coatings such as paints and varnishes, and elastomers, and are increasingly used in the automobile industry, autobody repair, and building insulation materials. How do you quench an isocyanate? isopropyl alcohol to ...
An inorganic semiconductor has to be processed within a vacuum, and extreme care must be taken in preparing materials for LEDs for wavelengths in the blue range. On the other hand, polymeric materials are very easy to process as they can be generated at ambient pressure through dip coating, ...
Polymers are both man-made and naturally occurring. Rubber, for example, is a natural polymeric material that has been used for thousands of years. It has excellent elastic qualities, the result of a molecular polymer chain created by mother nature. Another natural polymer is shellac, a resin ...
