The difference between plastic rubbers and rubber boots.
Here's a simple way to do it. Plastics are generally thermoplastic, and rubber is usually thermosetting. You can find a shoe and burn it. See if it's dripping when it's burning, and see if it's soft. If it fits, it's plastic.
There are the following differences:1, material is different, the former is plastic, and the latter is rubber;2, comfort is different, the former is relatively hard, uncomfortable wearing, and the latter is relatively soft.3, rubber shoes need good maintenance, and the former is not necessary.
Plastic and rubber are high molecular material, mainly composed of two kinds of carbon and hydrogen atoms, and some contain a small amount of oxygen, nitrogen, chlorine, fluorine, silicon, sulfur atoms, its special properties, use is also special. At room temperature, the plastic is not solid, hard, and tensile deformation of rubber hardness is not high., elastic, can be stretched, and stop pulling back to normal. This is due to differences in their molecular structure. Another difference is the plastic can be repeatedly recycled, while the rubber cannot be directly recycled, can only be processed and then reclaimed rubber, plastic and rubber. Available in the form of more than 100 to 200 degrees at 60 to 100 degrees. The morphological similarity does not include plastic rubber
The most essential difference between plastics and rubber is plastic deformation when plastic deformation occurs, while rubber is an elastic deformation. In other words, it's not easy to restore the original state after plastic deformation, and rubber is relatively easy. Plastic elasticity is very small, usually less than 100%, while rubber can reach 1000% or more. Most of the plastic molding process is completed, the product process will be completed; and after the rubber forming process, but also need vulcanization process.
Rubber boots will be oxidized and sun and high temperature can accelerate the aging of rubber products, make the hair soft and hard. Therefore, rainshoes must not long time sun, more do not insolate and roast. Also should avoid contact with coal sleeve, gasoline and other objects, because these chemical solvents can dissolve the rubber, the vamp is sticky. When wearing, do not cut with a broken glass, wire, nails and other sharp objects touch pinch, once you can not continue to use after shaving Water Leakage.
