There are 3 principal classes of polymers – thermoplastics, thermosets, and elastomers. Differentiation between these classes is best defined by their behaviour under applied heat. Thermoplastic polymers can be either amorphous or crystalline.

Examples of naturally occurring polymers are silk, wool, DNA, cellulose and proteins.

Synthetic polymers are human-made polymers. They can be classified into four main categories: thermoplastics, thermosets, elastomers, and synthetic fibers. They are commonly found in a variety of consumer products.

The eight most common types of synthetic organic polymers, which are commonly found in households are:

• Low-density polyethylene (LDPE)
• High-density polyethylene (HDPE)
• Polypropylene (PP)
• Polyvinyl chloride (PVC)
• Polystyrene (PS)
• Nylon, nylon 6, nylon 6,6.
• Teflon (Polytetrafluoroethylene)
• Thermoplastic polyurethanes (TPU)

Polymers fall into two categories:

• thermosetting plastic or thermoset.
• thermoforming plastic or thermoplastic.

Cotton fibers are the purest form of cellulose, nature’s most abundant polymer. Nearly 90% of the cotton fibers are cellulose.

And even our DNA is a polymer—it’s made of monomers called nucleotides. The first man-made polymers were actually modified versions of these natural polymers.

Wood itself contains polymers such as lignin, cellulose, and various hemi- celluloses but has very different properties from the synthetic polymers with which it is most often combined. Wood is less expensive, stiffer, and stronger than these synthetic polymers, making it a useful filler or reinforcement.

Salt is not a polymer. Common table salt is sodium chloride, which is an ionic complex.

A polymer is a very large, chain-like molecule made up of monomers, which are small molecules. It can be naturally occurring or synthetic. Since poly- means “many,” a polymer means “many parts.” You’ll find polymers everywhere: they’re what make spandex stretch and sneakers bounce.

Natural rubber is a polymer, a long, chain like molecule that contains repeating subunits. The term polymer comes from the Greek “poly” meaning many and “mer” meaning parts. The chemical name for natural rubber is polyisoprene. The monomer (meaning “one-part”) from which it is built is isoprene.

The word’s origins can be traced back to the 1600s, when the English used the term “rubber” as a reference to an object used for rubbing, or cleaning. The term found its way into the popular 16th century game of lawn bowling, which is similar to bocce ball.

Natural rubber is a polymer of isoprene (also known as 2-methylbuta-1,3-diene) with the chemical formula (C5H8)n. To put it more simply, it’s made of many thousands of basic C5H8 units (the monomer of isoprene) loosely joined to make long, tangled chains.

Hevea brasiliensis

Rubber is a natural product produced by plants and is present in many of the goods used in our daily lives. Nowadays, 99% of the natural rubber we use is extracted from a tree called Hevea brasiliensis.

Yes, rubber plant is capable of producing flowers and, subsequently, small fruits. But popular houseplant species such as rubber trees and their cousins, the weeping figs (Ficus benjamina), rarely bloom or yield fruits. …

In the wild, the rubber tree will grow to heights of 100 to 130 feet, and can live up to 100 years. Its most famous feature is the milky white sap, known as latex, which flows freely from the tree when a sliver of bark is removed.

Rubber Plant (Ficus Elastica) The rubber plant or rubber tree plant is one of popular Vastu plants. Vastu Shastra considers this plant as a very powerful indoors plant that brings good furniture, prosperity, and positivity to the family.

Most water meters should read a 4 at optimum moisture levels. Rubber plants need to be checked weekly during the growing season. A good sign that you are overwatering is yellow leaves. At the first sign of yellowing, decrease watering slightly and healthy green, glossy leaves should appear.
