Low-density polyethylene: LDPE Properties of Plastics The properties of plastics depend on the chemical composition of the subunits, the arrangement of these subunits, and the processing method. All plastics are polymers but not all polymers are plastic. Plastic polymers consist of chains of linked ...
Wild Birds Unlimited makes use of colorful new bags to attract seed buyers. The new bags are color-coded to represent the different seeds and blends it offers. The materials used for these bags are recyclable, low-density polyethylene. [SOURCE] Holli Mølle Organic Flour An environmentally frie...

Syntheticpolymers are produced in different types of reactions. Many simplehydrocarbons, such asethyleneandpropylene, can be transformed into polymers by adding onemonomerafter another to the growing chain.Polyethylene, composed of repeating ethylene monomers, is an addition polymer. It may have as many...
Plastic (Polyethylene) Artificial rubber (Polybutadiene) What are the 4 main polymers? The four main biologically important polymers are Carbohydrates Lipids Proteins Nucleic Acids There are several other types of synthetic polymers, including plastics, artificial rubber, and nylon. What is a...
In this article, we look at how Europe’s Bio Revolution could translate scientific strengths into new forms of biological innovation and impacts.
irreversible chemical bonds when cured, the bonding in thermoplastics weakens with temperature. Unlike thermosets, which decompose rather than melt, thermoplastics melt into a liquid upon heating. Examples of thermoplastics include acrylic, nylon, Teflon, polypropylene, polycarbonate, ABS, and polyethylene....
Several plastic implants, including polyethylene, polyvinylchloride, bakelite, polyamide, polystyrol, and polyurethane, led to the formation of sarcomas in rats, mice, hamsters, and dogs. The same applies to metals (gold, silver, and platinum) and other materials, such as ivory, window glass, ...
