1.Description of Gasket :
Ginseal Spiral-wound gaskets comprise a mix of metallic and filler ma- terial. Generally, the gasket has a metal (normally carbon rich or stainless steel) wound outwards in a circular spiral (other shapes are possible) with the filler material (generally a flex- ible graphite) wound in the same manner but starting from the opposing side. This results in alternating layers of filler and metal. The filler material in these gaskets acts as the sealing element, with the metal providing structural support.

2.Features of Gasket :
• Wide range of applicable working condition,high temperature and high pressure resistance,applicable to super low temperature and vacuum condition.Chemical resistant gasket is available under various medium,through change of composition of gasket.
• Strong stress compensation,stable and reliable sealing performance even under frequent pressure fluctuation condition.
• Perfect sealing performance.
• Normal requirement of flange surface finishing which contact with gasket.
• Easy installation and low pre-tightening stress of gasket.
• Heat treatment industry for furnace parts, fans, tube hangers, and baskets and trays to hold small parts.
• Chemical process industry to contain hot concentrated acids, ammonia, and sulfur dioxide.

4.Specifications of the Gasket:
1.A good compression ratio and elasticity.
2.With plastic appropriate, after pressing can adapt to the sealing surface and sealing surface uneven fill the gap, to ensure good sealing performance with the temperature and pressure in the system of alternating case.
3.With excellent corrosion resistance, not to be damaged in some extreme medium, does not have the expansion and contraction.
4.Under the condition of high temperature softening, does not creep; under the condition of low temperature hardening, does not shrink.
5.Have sufficient strength, when external load conditions, not be crushed; at high temperature, not blown out.
5.FAQ
Ask 1: Why some supplier give me the price much cheaper than you?
Answer:1.They wanna attract your attention,while you contact with them,they would raise the price by any reason.
               2.They willn't provide the high qualities to you cause it had the cheap price.
Ask 2:What the MOQ?
Answer:The MOQ should reach 800 kilograms
Ask 3:Should i pay for it If some product need molds?
Answer:I'm afraid you should pay for it,However,We would return it back when we get the first order.
Ask 4:Your price seems higher than others.
Answer:As you know,Price equals qualities.We have faith in our qualites.But it must be in the acceptable range

Q: What is the cause of the bursting of rubber products and how should they be improved?
Improvement measures: 1.. Adjust the molding sulfuration temperature, adjust the temperature of the upper and lower plate. 2. adjust the exhaust distance and exhaust time. 3. in strict accordance with the mixing process standards or adjust the formula and mixing process, avoid the use of time is too long to place material (fast cooked). 4., in the explosive edge position plus running trough. 5. control the weight of a single adhesive.
Q: When rubber products are hardened, what methods soften?
Either hardening or vulcanization. Vulcanized rubber becomes elastic rubber. This is an irreversible process. The elastomer can be changed into a plastic regenerated rubber by the desulfurization process.
Q: How long is the warranty period for EPDM?
(1). 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.(2). A rubber elastic body of thermosetting plastic hot melt, belongs to the hot cold setting. Rubber due to different types of sulfide species, its molding and curing temperature range is also a considerable gap, and even can be affected by climate change, indoor temperature and humidity affected. Therefore, the production conditions of rubber products need to be adjusted at any time. If not, the quality of the products may be different.(3) rubber products are made of rubber raw materials and used as raw materials made from the rubber compound of the mixer, and the formula is designed according to the characteristics of the required rubber products, and the required hardness of the products is determined. The product is made and molded by rubber flat vulcanizing machine. Finally, the product is processed by flying edge, and the surface of the product is treated smoothly without burrs.(4). Aging test of rubber products aging test belongs to the category of rubber aging refers to rubber and products in the processing, storage and use of the process, due to the comprehensive effect of internal and external factors caused by the performance of the structure change, then the loss of use value phenomenon. They are crazing, sticking, hardening, softening, powdering, discoloration, mildew, etc..
Q: What kinds of rubber are edible grade safety rubber?
According to the requirements of tolerance solution, select the appropriate rubber material (general rubber -- basic environmental protection without pollution, mainly small rubber) material, plasticizer, filler to use food grade raw materials such as calcium carbonate, not to use food grade industrial grade;
Q: Classification of other rubber sheets of wear-resistant rubber plates
RIT ceramic abrasion resistant rubber sheetRubber surface with uniform ceramic block, can drive the roller and the conveyor belt between the grip of excellence, usually used in all kinds of extreme working conditions, such as muddy, wet, and high wear roller under the environment of rubber processing.
Q: How can rubber and mould not be bonded when producing rubber products?
Mold release can not be solved, we can only start with the mold structure. Because the main reason for adhesion is the complex structure of the product, resulting in strong vacuum adsorption between the mold and the mold. In view of this, we can do a few more exhaust at the appropriate location of the mold. If allowed, you can also modify the product structure, of course, this is unlikely. But really can not do it, this is the best solution.
Q: What kinds of vulcanized rubber do you have?
According to the sources and methods of raw materials: rubber can be divided into two categories: natural rubber and synthetic rubber. Among them, the consumption of natural rubber accounted for 1/3, and the consumption of synthetic rubber accounted for 2/3.
Q: Half finished rubber film surface white is going on
Rubber is a latex made from rubber, tree, rubber, and grass. It is made of flexible, insulating, impermeable and air. 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. Rubber products are widely used in industry or in all fields of life.
Q: How can rubber products prevent fading?
That is to add UV absorbers, white, then add more titanium dioxide, there is no good way, as well as your choice of pigment, as far as possible difficult to fade, such as inorganic pigments.
Q: What are the hazards of waste rubber and how can they be used for regeneration?
The disposal of waste rubber is one of the serious problems facing people today. In order to meet the requirements of materials to improve the performance of rubber, towards high strength, wear resistance, stability and aging resistance of the direction of development, but also caused a long period of rubber not biodegradable waste after a large number of waste rubber, causing than plastic pollution (white pollution) more difficult to deal with the black pollution. On the other hand, precious rubber resources are wasted.
