Q:When were rubber wheels invented?

A: In 1839 an American, Charles Goodyear, discovered a method to mqke rubber stronger, more elastic, and less sticky. In 1845 the first air-filled rubber tire was patented by Scottish inventor Robert W. Thomson, but it was not until 1888, when British inventor John Boyd Dunlop patented his tire design, that the rubber tire industry really started.

Q:What is a rubber?

A: It is a sticky, elastic solid produced from a milky liquid called "latex," which has different properties than the sap found in trees. Although latex is found in the bark, roots, and stems, branches, leaves, and fruit of over 400 different plants and trees, the bulk is found, and extracted, from the inner bark of the branches, and from the trunk, of the rubber tree. Quite simply, it would not be cost-effective to extract the latex from rubber producing plants, such as the dandelion, the milkweed, and the sagebrush. Just visualize some poor soul laboring over one of these with a syringe!

Rubber, derived from the gum of a tree, has existed since prehistoric times. For example, fossils of rubber-producing plants date back almost 3,000,000 years. Crude rubber balls, discovered in ruins of ancient Incan and Mayan civilizations in Central and in South America, are, at very least, 900 years old. Natives of Southeastern Asia used rubber, prepared from the "juice" of trees to waterproof their baskets and jars. Even Columbus, on his second voyage to the New World, observed Haitian natives playing with balls made from "the gum of a tree."
Latex consists of tiny particles of liquid, solid, or semi-fluid material, that appears in the form of a watery liquor, not to be drunk! The breakdown on this watery liquid is only about 33% rubber, with the remainder being, not surprisingly, water! When the rubber particles in the latex join together, they form a ball of rubber.
Rubber producing plants grow best within 10 degrees of the Equator, where the climate is hot and moist, and the soil is deep and rich. For this reason, the area of about 700 miles on each side of the Equator is known as the "Rubber Belt." Brazil, from whence the best, and top-producing rubber tree hails, is firmly planted within the Rubber Belt. This Latino tree with a Latin name, Hevea brasiliensis, produces approximately 96% of the world's supply of natural rubber, and now is cultivated in other Rubber Belt countries.
Most likely, the French, prior to the 1800s, were the first white men to take advantage of rubbers' elasticity. They manufactured "rubber bands" for use with their garters and their suspenders, to help to keep their pants up. Rubber belts did not exist at that time.

Q:What Is Polyurethane?

A: Polyurethane is a synthetic material that is used in various applications in nearly every field imaginable. It is renowned for its durability and flexibility and can be produced in a number of different forms based on what it will be used for. Everything from airplane wings to tires can be made with polyurethane.
·

Q: Polyurethane Identification

A: Polyurethane is identified as a polymer, which is basically a string of smaller molecules known as monomers. In this case, it is a string of urethane. An entire polyurethane chain consists of nitrogen, carbon and oxygen atoms double-bonded to a hydroxyl group, which is also known as an alcohol and is a bonded molecule of oxygen and hydrogen. When various other elements are added to this basic chain, the polyurethane changes, sometimes becoming a rubbery solid, liquid or even a foam.

Q: Polyurethane Features
A: Polyurethane can be manufactured synthetically to have a number of different features, depending on the specific molecules that are added to its basic string of urethane molecules. Some of the more sought-after features of polyurethane are its elasticity and durability. This makes it popular for use with tires and other rubber devices that need to be strong and bendable. Polyurethane can also be made into a squishy, foam-like substance or a substance similar to glue, with the same bonding ability.

Q Polyurethane Function

A: Polyurethane is used in so many different fields and in so many different forms that it is one of the most used synthetic materials. Look around your house, and you will be able to find many things that are made of polyurethane. Much of the firmer rubber used for various reasons is polyurethane, and because as an adhesive it is water and heat resistant, it's used in outdoor and exceptionally hot areas. It is also used in walls as extra padding, and in foam form for soundproofing.

Q: Warning
A: For the most part, polyurethane is not a dangerous substance--which is why there is no limit on exposure to it. However, there are times where it can let off harmful chemicals, including carbon monoxide and other hazardous fumes. This is generally when polyurethane is heated to over 200 degrees C. For this reason, handling this polymer at high temperatures should be done with gloves and a personal breathing apparatus.

Q:Polyurethane Benefits
A: One of the major benefits of polyurethane is its resistance to heat and flames. Using the substance means that it will offer protection from this, which makes it particularly beneficial in the home and in making important substances and materials. It is often used as a coat for wood, plastic or other substances because of this protective property.
