Q:Why does rubber stink?

Because of the original gum problem, such as PU or polyurethane will have a foul smell.Highly elastic polymer material with reversible deformation of rubber. It is elastic at room temperature and can produce great deformation under very little external force. It can be restored to original state after removing external force. Rubber is completely amorphous polymer, its glass transition temperature (T, g) is low, the molecular weight is often large, more than hundreds of thousands.

Q:What material is the rubber used in the tires?

The tyre is known, usually made of rubber materials, a solid tire and pneumatic tire parts, pneumatic tyre and tubeless tire composed by.

Q:Which is better waterproof performance, neoprene or silica gel?

Silicone rubber (Silicone, rubber), sub heat vulcanizing (high temperature vulcanized silica gel HTV), room temperature vulcanized (RTV), in which room temperature vulcanization type and polycondensation reaction type and additive reaction type.

Q:How to make white rubber products do not yellow or delay yellowing time?

Then aging is divided into thermal aging, oxygen aging, ozone (electrostatic belongs to ozone, because static electricity produces ozone). Gas corrosion aging, heavy metals, oxidation aging. Reaction aging. UV aging and so on.

Q:How does rubber mobile phone cover change yellow?

Generally discarded, disposed of, replaced by new ones.Can be used to deal with non toothpaste brush view can restore the original color!

Q:Is polyurethane and polyurethane rubber one thing?

Polyurethane is a very special polymer, it is composed of hard and soft segments, the hard part of Tg is very low, with plastic characteristics, soft section of Tg is higher than room temperature, a lot of rubber characteristics. In the process of synthesis of polyurethane, by controlling polymerization, the proportion of hard segment and soft segment of polymer can be adjusted, so that polyurethane can be expressed as plastic or rubber.Rubber shoes, excluding plastic shoes, should not be included in general sense. Common sense says in rubber overshoes, it is the waterproof shoe that rains commonly, army shoe, plastic shoe has slipper commonly.

Q:What's rubber skin?

Rubber (Rubber): highly elastic polymeric material with reversible deformation. It is elastic at room temperature and can produce great deformation under very little external force. It can be restored to original state after removing external force. Rubber is completely amorphous polymer, its glass transition temperature (T, g) is low, the molecular weight is often large, more than hundreds of thousands.

Q:What is food grade natural rubber?

Is mainly made of natural rubber, made of natural rubber products, through the relevant national food contact using rubber testing standards, to reach the food grade.

Q:What is the specific gravity of natural rubber?

Natural rubber is elastic high polymer compound natural rubber tree cultivation, by cutting off the latex prepared by the steps of dilution, filtration, condensation, rolling and drying, commonly known as raw rubber or rubber. According to different preparation methods, there are wrinkle sheet gum, tobacco sheet glue and so on.

Q:What does rubber mean?

High elastic polymer compound. It is divided into two kinds: natural rubber and synthetic rubber. Natural rubber is made from rubber, tree, rubber, grass and other plants. The synthetic rubber is obtained by polymerization of various monomers.
