Gloves

Gloves have been made of many materials including cloth, knitted or felted wool, leather, rubber, latex, neoprene and metal (as in chain mail). Modern gloves made of kevlar protect the wearer from cuts. Gloves and gauntlets are also integral components of pressure suits and spacesuits such as the Apollo/Skylab A7L which went to the moon. Spacesuit gloves must combine extreme toughness and environmental protection with a degree of sensitivity and flexibility if the astronaut is to do any manual work.
Today gloves are made around the world. Most expensive women's fashion gloves are still made in France, with some made in Canada. For cheaper male gloves New York State, especially Gloversville, New York is still a world centre of glove manufacturing. More and more glove manufacturing is being done in East Asia, however.

Tyres

A tire or tyre is a device covering the circumference of a wheel. It is an essential part of most ground vehicles and is used to dampen the oscillations caused by irregularities in the road surface, to protect the wheel from wear and tear as well as to provide a high-friction bond between the vehicle and the ground to improve acceleration and handling.

Rubber


Rubber is an elastic hydrocarbon which occurs as a milky collodial suspension (known as latex) in the sap of several varieties of plants. Rubber can also be produced synthetically.
synthetic rubber is made through the polymerization of a variety of monomers to produce polymers. These form part of a broad study covered by polymer science and rubber technology. Its scientific name is polyisoprene.
Rubber has many uses. Most industrial uses are in vibration control and dampening used in automotive components such as stabilizer bushings, jounce bumpers, and motor mounts. Rubber is also used to dampen blows from interlocking equipment and creating seals.
