3. The products should be storedat room temperature and be kept away wet and/or heat source.

4. It is essential, as with allpressure-sensitive tapes, that the surface to which the tape is applied must beclean, dry, and free of grease and oil.

5. The users should take test anddo trial-application on the above products before coming into application so asto witness and ensure suitability for their special purpose and technique.

Q:What kind of rubber coated aluminum alloy (metal) better: White Silicone, or at cyanide rubber, you have to brush the surface of metal binder, general is muruk we do, rubber products, these things often encounter

Q:What about the Poisson's ratio and modulus of elasticity of three yuan ethylene propylene rubber (EPDM)?: Three yuan ethylene propylene is ethylene, propylene and non conjugated diene three copolymer. Diene has a special structure, only one of the two keys to copolymerization, unsaturated double bond, mainly as the chain. Another unsaturated polymer will not become the main chain and will only become side chains. The main polymer chain of three yuan ethylene propylene is completely saturated. This property allows three yuan ethylene propylene to resist heat, light, oxygen, especially ozone. Three yuan propylene is essentially non-polar, resistant to polar solutions and chemicals, low water absorption, and good insulation properties.

Q:Why does rubber burn black smoke?: So, when rubber burns, it does not burn completely. There are many black carbon, which form black smoke

Q:Rubber soaked with hot water will not come out harmful substances?: Chloroprene rubber is electrical insulation, cold resistant performance is poor, rubber is not stable in storage. Neoprene is widely used, such as the manufacture of transport belts and belts, wires and cables, and the manufacture of oil resistant hoses, gaskets, and chemical resistant equipment linings.

Q:What are the causes of the rubber products breach?: Rubber aging is a common problem of rubber products, and aging is mainly due to internal structure or component is easy to aging due to weakness, such as unsaturated double bond, branched, carbonyl, hydroxyl and so on; at the end, the main external or environmental factors are sunlight, oxygen, ozone, heat, water and mechanical stress force, high energy radiation, electricity, industrial gas, water, salt fog, fungi, bacteria, insects etc..

Q:What is the difference between a thermoforming machine and an injection molding machine in a rubber plant?: A press forming machine is a machine that changes the solid material into a definite shape by pressure. The injection molding machine changes the viscous semi solid to a certain shape by pressure.

Q:What are the uses of ethylene propylene rubber?: In the electrical and electronic industries, the main use of ethylene propylene rubber excellent electrical insulation, weather resistance and corrosion resistance, in many electrical components used in this kind of rubber. For example, the production of cables with ethylene propylene rubber, especially submarine cables, is replaced by EPDM or EPDM/PP instead of PVC/NBR. The insulation performance and service life of cables have been greatly improved. In the transformer insulation pad, electronic insulation sheath is also a large number of ethylene propylene rubber production.Ethylene propylene rubber combined with other rubber is also a great field of ethylene propylene rubber applications. EPDM can be used in conjunction with other rubbers to improve performance and reduce costs. But due to various complex agents on the affinity of different polymers, covulcanization depends on the polymer crosslinking efficiency of different polymers and may not reach the molecular level compatible blend, but there were no phase separation system. The unequal distribution of complexing agents has a major impact on the properties of ethylene propylene and rubber.

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:Process for producing rubber products: Rubber elastic, lack of necessary processing plasticity properties, therefore not easy to process. In order to improve the plasticity, so the rubber mastication, so the mixing of ingredients easily dispersed in rubber, which also helps to improve the permeability of the fabric into rubber and molding in rolling and molding process. The long chain molecular degradation were called plasticity forming process of mastication. Mechanical plastication and mixing two kinds of thermoplastic plastic mixing method of rubber. Mechanical plasticization is the reduction of long chain rubber molecules at shorter temperatures through the mechanical extrusion and friction of the extruder, which changes from a high elastic state to a ductile state. Hot hot mastication is to pass into the rubber in the compressed air in the heat and oxygen under the effect of the degradation of long chain molecules to obtain shorter plasticity.

Q:How to distinguish between silicone hose and rubber tube by appearance?: Smell, silicone no flavor, rubber flavor, silicone general flexibility better, rubber mechanical better
