Skin, hair, and nails are made of keratin, a protein. Silk is a protein, too. Chitin, the material of the lobsters' and insects' exoskeleton, is a polysaccharide similar to starch.
Some examples: - plastics have a very low density - plastics are not corroded - platics are easily machined - plastics are non-corrodable
Cellulose: Found in plant cell walls, it is the most abundant natural polymer. Chitin: Found in the exoskeletons of arthropods and the cell walls of fungi, it is a versatile natural polymer. Casein: A protein found in milk that can be used to create biodegradable plastics.
A wellknown example is bakelite.
Plastics are usually derived from petroleum or natural gas.
Examples of natural fibers include cotton, wool, silk, jute, and hemp. These fibers are sourced from plants and animals, making them biodegradable and environmentally friendly.
natural rubber and much more! x
which of these natural resources is not being renewed
Yes
Biodegradable plastics are plastic materials that degrade through the natural process of living organisms into humus, gas, water or other basic elemental materials. Non-biodegradable plastics are any plastics that either do not break down at all or plastics that require mechanical or chemical breakdown. PLA and oxodegradable plastics are examples of non-biodegradable plastics. PHA and ENSO plastics are examples of biodegradable plastics.
No. Plastics are mostly made from fossil fuel oil, so they're not renewable and they're not natural either, but man-made.

Medicine, Polymers & Plastics
Plastics have many applications in medicine. Some examples are IV Tubes, Prostectics, and Instruments.
Examples of thermosetting plastics (or just thermosets) include amino, epoxy, and phenolic and unsaturated polyesters.
Plastics that can be broken down by microorganisms are known as biodegradable plastics. These types of plastics can be decomposed into natural elements like water, carbon dioxide, and biomass by bacteria, fungi, or other microorganisms, helping to reduce their impact on the environment.
Molded plastics is a huge business. Some examples of molded plastics include piping that carries water and sewage when constructing houses, housing for electrical goods such as DVD players and television sets and even parts for aeroplanes making them more fuel efficient.
Some examples of PET plastics include water bottles, soda bottles, food containers, and polyester clothing. These plastics are commonly used for packaging beverages, food, and personal care products due to their lightweight, durable, and recyclable properties.
