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: Excuse me, what is in the rubber rubber, glue them, what is the difference?
Rubber is a kind of polymer material with high elasticity, is the parent material manufacturing of rubber products, generally refers to the rubber unvulcanized. Heat the raw rubber to about 120 degrees and keep it warm for more than 5 minutes.
Q: Are natural latex rubber products?
In the fresh latex without any substance, the rubber hydrocarbon accounts for only 20%-40% of the total amount, and the remainder is a small amount of non rubber components and water.
Q: What are the rubber parts for the car?
Filter rubber parts, cloth (diaphragm), injection pump sealing ring, car frame sealing strip, door seal..... There are many, the car inside the big, small, a lot of rubber products. Watch more and you'll see.
Q: Advantages and disadvantages of rubber products
Styrene butadiene rubber SBR(Styrene Butadiene Copolymer) and butadiene styrene copolymers, compared with natural rubber of uniform quality, less foreign body, has better wear resistance and aging resistance, but the mechanical strength is weak, can be combined with natural rubber mixing. Non - oily material advantages: low cost, good water resistance, hardness below 70 with good elasticity, high hardness with poor shortcomings: compression, does not recommend the use of ozone, acid, oil, oil and fat ester and most hydrocarbons. Widely used in tire industry, shoes, cloth and conveyor belt industry etc..
Q: Explain why butyl rubber is more resistant to oxidation and aging than other elastomers, such as natural rubber
Ding Ji rubber (abbreviation: IIR English Name: Isobutylene-isoprene Rubber)Ding Ji rubber is an elastomer made from a small amount of isoprene (butadiene) copolymerized with isobutene with a high degree of saturation. Generally do not need refined refining, pay attention not toBlends with unsaturated rubber with low degree of unsaturation. Use super accelerators and less sulfur or cure with resin. Due to the slow vulcanization rate of ordinary butyl rubber and high unsaturated rubberIts poor compatibility, self adhesion and co adhesion were not good, and then it was modified by halogenation, which improved its curing rate and compatibility with other high unsaturated rubber
Q: Is rubber flame retardant?
Mainly to see the use of related products, for example, the glass door rubber strip is flame retardant, and the vehicle's internal and external tires are not flame retardant.
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 chapped rubber products?
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 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.
Q: What are the bridge rubber air bags used for?
After the concrete is poured, the vibrating bar is vibrated simultaneously from both sides, so as to prevent the core mold from moving to the left and the right. And the vibration bar segment head can not touch the core mold, so as not to wear and tear gas leakage.
