Q: What is the tensile strength of silicone rubber?: The tensile strength range of silicone rubber is 3.4-14.7Mpa, depending on the formula!

Q: What's the difference between rubber and silicone?: In choosing rubber, it requires specific performance requirements such as hardness, tensile strength, compression, deformation, wear, tear, use of the environment, etc..

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: What is the lowest cost material for the synthesis of rubber?: Polypropylene ethylene propylene rubber, ah, as if a few domestic, oh, raw materials are not expensive, but the technology is difficult, but it is very simple to say, on the two synthetic. Jilin Petrochemical made decades of synthesis, products or not like us.

Q: What's rubber skin?: High elasticity polymer. The word "rubber" comes from the Indian language "cau-uchu", meaning "weeping tree"". Natural rubber is flowing out from the Hevea latex when tapping after solidification and drying process (see photo). In 1770, British chemist J. Priestley discovered that rubber could be used to erase pencil writing. The material used at that time was called rubber, which has been used so far. The molecular chain of rubber can be crosslinked, and the crosslinked rubber can recover quickly when it is deformed by external force, and has good physical and mechanical properties and chemical stability. Rubber is the basic raw material of rubber industry. It is widely used in making tyres, rubber hoses, tapes, cables and other kinds of rubber products.

Q: What are the ingredients in the tires?: The tire carcass, is composed of a buffer layer (or belt), tread, sidewall and bead. Tyre section can be divided into several separate regions: crown area, shoulder area (tread slope), flex area (sidewall area), and strengthening the bead region.

Q: Can the rubber surface be painted with paint?: The surface of the rubber is sprayed with paint, and it wants to be covered with black paint, but I don't know the effect of paint on rubber for a long time. Rubber is mixed rubber or rubber paint is used!

Q: What are the causes of the rubber products breach?: Measures to prevent aging: from the point of view of aging, one of the main reasons is the polymer structure itself. Therefore, it is important to improve the structure of polymers to improve their aging ability. For example, in rubber vulcanization, there are still unsaturated double bonds, and rubber products in use and it is difficult to avoid the erosion of sunlight, oxygen, ozone, so people on the synthesis of new varieties, to avoid or reduce the polymer chain of rubber double bonds, such as ethylene and propylene two monomer by copolymerization made two yuan B two rubber, different from other synthetic rubber is one of the major characteristics in the structure of the backbone is not completely saturated with double bond, making it the most ozone resistance, chemical resistance, high temperature resistant rubber aging; there is a kind of antioxidant, such as adding oxygen or ozone to prevent aging caused by antioxidants. Add UV stabilizers, heat stabilizers, preservatives and other unfavorable factors, and caused by aging.
