REMARKS:

1.    The data above are typical results and subject to change withoutnotice.

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

3.    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.

4.    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:How to distinguish between rubber and polyvinyl chloride?
Adhesive (Rubber): highly elastic polymeric material with reversible deformation.At room temperature, elastic, in a small rubber under the action of external force can produce greater deformation, remove the external force can restore the original state. Rubber is a completely amorphous polymer, its glass transition temperature is low, the molecular weight is often very large, more than hundreds of thousands.
Q:What is a rubber accelerator? What role?
The accelerator for natural and synthetic gums has a broad range of vulcanization, which can be used alone or in combination with two dithiocarbamate, glucosinolates, guanidine, and other basic promoters. Mainly used in the manufacture of tires, adhesive tape, rubber shoes and other industrial rubber products.
Q:What is the relationship between the hardness and tensile strength of rubber pad?
The main factors affecting the tensile strength of rubber are: the main valence bond, intermolecular force and polymer chain flexibility of macromolecular chains. The relationship between tensile strength and structure of rubber: the intermolecular forces are large, such as polarity and rigid groups;
Q:How can I remove the rubber flavor on rubber products? It smells terrible
This odor is stubborn, more difficult to solve in a short timeThe peculiar smell of a small rubber component in my car used for a week before cleaning it. If the price is not high, I suggest you change it.
Q:What about rubber molding, foaming and layering?
Foaming1 vulcanization is not sufficient, the temperature is too low or time is too short, so that the volatile compounds produced during curing have not been cleaned out;2, under the pressure of vulcanization, the trapped gas and sulfur volatile matter can not be discharged in time3, there is air or moisture in the glue;4, curing temperature is too high, the surface of the gum material premature vulcanization, hindered the glue material in the steam, air free precipitation5 vulcanization speed of material is too fast
Q:What kind of rubber products are expensive?
Rubber products are expensive and the cost of rubber is naturally high, so it can be analyzed from the following points:1, the raw material, choose what kind of natural rubber, determines his price, such as natural rubber and hydrogenated nitrile rubber price is 20 times worse;2, with the choice of mixture, environmental protection and environmental protection agent, the price is also very different;3, the rate of gum content, the higher the gum content, the higher the cost of nature;
Q:What are the forming methods of rubber products?
In rubber products, the main molding technologies are molding, forming, transfer, forming, wrapping, molding and injection molding.
Q:Process for producing rubber products
In order to adapt to the different conditions of use, to achieve a variety of performance, also in order to improve the performance of rubber products and reduce the cost must be added with different chemicals in raw. Mixing is the mixing of raw rubber and compound mixing, placed in the mixing machine by mechanical mixing with the role of agent, uniformly dispersed in rubber in a process. Mixing is an important process in the production of rubber products. If the mixture is uneven, it can not give full play to the role of rubber and mixture, and affect the performance of products. People get glue mixing after the production of various rubber products for mixing it is semi-finished materials, rubber products, commonly known as the glue are usually sold as a commodity buyers can directly process material, need to use the rubber vulcanization. According to the formula, a series of different grades and varieties with different performances are selected.
Q:How can the rubber shoes be dyed?
The rubber material of the shoe edge was stained with a soft brush gently on top with a little toothpaste. The fluoride contained in toothpaste is a good cleaning detergent.
Q:EPDM rubber foam?
Three yuan ethylene propylene diene rubber (EPDM) is used as matrix, and azo two, AC and HOBSH are used as foaming agents, in order to systematically and quantitatively study the preparation process of EPDM foam material and the relationship between structure and properties of foamed material. At present, most of EPDM rubber foam material with low reinforcing carbon black filler, fine particles of carbon black can avoid the difficult problem of dispersion and high viscosity, but now the industry of light colored rubber products demand more and more, so this paper using silica as reinforcing filler rubber, studied the preparation process of EPDM foam rubber and the effects of molding conditions on the foaming process. Subsequently, the change of accelerator, filler, foaming agent and the amount of paraffin oil was analyzed. The curing properties, mechanical properties and SEM analysis were carried out, and the influence of various factors on the structure and properties of foamed material was discussed. The influence law of each formula factor on foaming is summarized, and the optimum formula dosage is expected to be found. Finally, we also through the compression behavior of stress-strain curves of EPDM rubber foam materials with different density, the energy absorption efficiency of E and I analysis of the ideal parameters of EPDM foam energy absorption characteristic of absorbing ability of W and.
