Q:What's the difference between silicone products and rubber products?

Physical properties are different: nitrile rubber products waterproof, weak acid, weak base, anti oil, etc., silicone rubber waterproof, environmentally friendly, non-toxic, good elasticity, appearance, color and appearance.

Q:How does the rubber part of the watch become yellow?

The rubber strap is yellow and rubbed with the weld polish. Remember, the ratio is 1 to 70.

Q:Can PVC blend with rubber?

Ding Qing rubber is highly polar and can mix with any proportion of PVC. Other polar rubbers, such as chlorinated polyethylene and chlorinated polyethylene, can be mixed.

Q:What is the rubber composition of sole?

The sole of high pressure polyethylene and rubber flavor, rubber and plastic used together.Student: Rubber soled heavy, expensive, not resistant to oil, heat. Variable color.

Q:What are the causes of fracture in rubber products?

Rubber products appear broken phenomenon, mainly for the following reasons:1, rubber products for a long time led to the phenomenon of fracture;2, too tired lead to rubber products broken;3, long-term exposure to ultraviolet light will cause rubber products broken;4, in the production of the use of chemical additives and materials conflict, resulting in incompatible and broken;5, the production process, the release of time is not appropriate, resulting in fracture (such as scratches);6, abrasive structure is irrational, lead to fracture;7, the use of materials is irrational, leading to fracture is also common;8, materials placed too long, in use, resulting in broken products, resulting in waste.

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:How can I get rid of the rubber?

One way is to use rubber deodorant is a kind of used to remove or reduce the acid degradation, all kinds of rubber produced in the processing or in the process of the use of alkoxy compounds, aldehydes, vinyl compounds, ammonia, CO2 plastic smell of chemical additives, the smell if inhaled for a long time will stimulate the senses give a person, discomfort or even harmful to the body, have two times of pollution to the environment, the chemical composition of different varieties of rubber and odor molecules are different, and in the actual development of Chinese ocean chemistry and etc. Ma'anshan Keli chemical is used in chemical chelation is also used, is the other mechanism, in addition to taste rubber both the rubber agent itself, also want to consider a variety of additives such as odor curing agents released, in addition to the use of rubber ingredients to improve rubber products and improve the level of environmental protection, rubber The production environment is of great help to the comprehensive utilization of regenerated rubber resources. A form of powder or liquid used in rubber, usually based on odor and odor characteristics

Q:What is the specific gravity of natural rubber?

The natural rubber has a specific gravity of 0.90-0.93 grams per cubic centimeter.

Q:What kind of material does the shockproof rubber cushion usually choose? What's the hardness?

Of course is to choose butadiene rubberThe biggest characteristic is the molecular structure, mainly for the CIS structure, so the elasticity, cracking resistance and dynamic performance is excellent, and the rubber pad shock proof function is guaranteed, and the rubber cushion life is guaranteed, and the hardness is about 55.

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.
