Q: What are the uses of ethylene propylene rubber?: Ethylene propylene rubber (EPR) is the most widely used automotive industry. It is mainly used in automobile seals, radiator hoses, spark plug sheaths, air conditioning hoses, rubber pads, hoses and so on. In the automotive sealing industry, mainly the use of EPDM, elastic characteristics of ozone resistance, weather resistance, EPDM rubber type ENB has become a main material of automobile rubber seal, domestic consumption has exceeded 10 thousand tons, but due to its variety, half rely on imports.

Q: What is the difference between silicone rubber and silicone rubber?: Silica gel is also called "silicon rubber" because of different fields so organic silica gel has become an indispensable tools in our lives, but also more than a silica silica aggregate, silica gel in the molding of silicone products manufacturers is a popular said polysiloxane silicone rubber is only a kind of synthetic rubber is a kind of non-toxic solid silicone silicone rubber. Because no accurate statement so that both of them are called organic silica gel, silica gel is a kind of solid crystal, by molding to produce silicone products applied to various places with liquid silicone are two production methods, such as "silicone" after the encounter them divided into organic and inorganic silica gel, silica or must be clear is polysiloxane synthetic silicon rubber, can also be understood as the silicon rubber is silicon A synthetic silicone rubber.

Q: Several aspects of rubber aging performance and how to identify them: Heat: increasing temperature can cause thermal cracking or thermal crosslinking of rubber. But the basic function of heat is activation. Increase oxygen diffusion rate and activate oxidation reaction, so as to accelerate the speed of rubber oxidation reaction, which is a common aging phenomenon - thermal oxidative aging

Q: How to maintain and store the rubber material?: Rubber itself is a shelf-life, you can ask the supplier to warranty, above all, as fillers, such as calcium carbonate, carbon black, long time no problem, also have a shelf life of antioxidant promoter, especially individual species. When storing, pay attention to fire prevention, moisture-proof, away from the high temperature, avoid direct sunlight, of course, the general "first in first out" is a must follow the truth.

Q: Is vulcanized sole good or rubber sole is good?: Rubber base, vulcanized bottom are basically the same, rubber vulcanization is only the process of shoe-making, rubber is the bottom of the way vulcanized and uppers together, it is more difficult to open

Q: What kind of materials should be used for rubber products to keep the brightness of the mirror for a long time?: It is important to use recycled material as a high light material. If the selected material is not available, then it is not effective. It must be pure, only ABS.PMMA, or PC/ABS. There is material, it is best not to contain white material, mottled with a little transparent, is the best.

Q: How to identify the tire rubber is raw or cooked: Rubber molding, after pressing, the elastic body is within the cohesion can not be eliminated, the molding die, often have a very unstable contraction (rubber shrinkage due to rubber vary), required after a period of time, and can be stable. Therefore, when a rubber product design at the beginning, regardless of formula or mold, it is necessary to carefully calculate the coordination, if not, it is easy to produce product size instability, resulting in lower quality products.

Q: What is the temperature of ordinary silicone rubber resistant to low temperature?: Because the molecular structure of silicone rubber is amorphous, the temperature has little influence on its properties, and it has good cold resistance. The brittleness temperature of the general organic rubber is from -20 DEG C to -30 DEG C, while the brittleness temperature of the general silicone rubber is between -60 and -70 degrees centigrade. When the rubber is introduced in 7.5 (mol)% phenyl, brittle temperature of silicone rubber can be reduced to -115 DEG C, remain elastic at -90 DEG C and can use.

Q: Is there any poison in the processing and testing of rubber products? What about the salary?: Rubber products processing and testing of this work has low toxicity, pay attention to ventilation, strengthen physical exercise, no problem!! The salary is average, basically between 2500--3500!

Q: What are the disadvantages of a rubber roof?: Housing rubber roof area must be greater than the housing area, mainly for water and rubber, heat up, cold weather.
