Raw Natural Rubber Vulcanized Natural Rubber Soft and sticky Comparatively hard and non-sticky Low tensile strength and not very strong High tensile strength and very strong Low elasticity High elasticity Can be used over a narrow range of temperature from 10 to 60 degrees centigrade Can be used over a wide range of temperature from -40 to 100 degrees centigrade Low abrasion resistance High abrasion resistance Absorbs a large amount of water Absorbs a small amount of water Soluble in solvents like ether) carbon disulp hide, carbon tetrachloride, petrol and turpentine Insoluble in all the usual solvents Raw Natural Rubber Vulcanized Natural Rubber Soft and sticky Comparatively hard and non-sticky Low tensile strength and not very strong High tensile strength and very strong Low elasticity High elasticity Can be used over a narrow range of temperature from 10 to 60 degrees centigrade Can be used over a wide range of temperature from -40 to 100 degrees centigrade Low abrasion resistance High abrasion resistance Absorbs a large amount of water Absorbs a small amount of water Soluble in solvents like ether) carbon disulp hide, carbon tetrachloride, petrol and turpentine Insoluble in all the usual solvents
Vulcanized Rubber is hard and non-sticky, very strong, it has high elasticity, and can be used over a high range of temperatures. It also absorbs a small amount of water.
Stronger, more durable tires. Because it was vulcanzed, it gave the tire more elasticity and made it waterproof and "winter proof"
Charles Goodyear
yeah okay so you do that.
A hockey puck is a one inch (1") thick and three inches (3") in diameter, and roughly 6 oz piece of vulcanized rubber
== == There is only one type of hockey puck. It is made of vulcanized rubber. The size and weight are regulated. It is a three inch disk, one inch thick, and weighs between five and a half ounces, and six ounces. Black pucks=6 oz. Blue pucks=4 oz. Orange pucks=10 oz.
football - string And leatherAnswerLeather. The Incas invented the first football using leather. Answerpig or bull bladder.First they use to use cloth back in Europe correct
Vulcanized rubber has disulfide crosslinks and is hard and strong.Natural rubber has no crosslinks and is soft and weak.
Vulcanized Rubber can cost anywhere from one dollar to twenty dollars by the sheet. There are also vulcanized rubber molds you can purchase that range around twenty five dollars.
