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.

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:What's the delivery circle times ?
Answer:About 2 weeks and we would give the accurate time when we know the quantity.
Ask 5:What's the FOB port?
Anser:Our port are Shanghai and Ningbo usual.

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:How long does the rubber last?
In addition, aging has ozone aging, weather aging, heat aging and so on. Ding Qing rubber is not resistant to ozone, the time is not long, it will appear aging.
Q:What is the lowest cost material for the synthesis of rubber?
There are many kinds of synthetic rubber. Many kinds of materials are used in synthesis, which material is lower or can not be measured
Q:What's rubber skin?
Rubber (Rubber): highly elastic polymeric material with reversible deformation. It is elastic at room temperature and can produce great deformation under very little external force. It can be restored to original state after removing external force. Rubber is completely amorphous polymer, its glass transition temperature (T, g) is low, the molecular weight is often large, more than hundreds of thousands.
Q:What are the application fields of waste tire rubber powder?
Waste tire rubber powder from 900 to 1200 waste tire as the main raw material, the production method of low temperature refrigeration by air turbine (0.425mm) 40 mesh to 200 mesh (0.0750mm) crumb rubber with high fineness, tensile strength, the proportion of small, good liquidity.
Q:Rubber products are not allowed to touch oil products, but why can rubber gloves be contacted daily? What's the point?
Most rubber materials are not resistant to oil, some rubber materials are resistant to oil, such as nitrile rubber, etc., the family commonly used detergent on rubber gloves did not affect.
Q:PVC conveyor belts and rubber belts differ from each other in their respective advantages
PVC is actually a vinyl polymerization substance, whose material is a non crystalline material. PVC materials often use stabilizers, lubricants, auxiliary processing agents, pigments, anti shock agents and other additives in practical use. Is not flammable, high strength, excellent resistance to climate variability and geometric stability. PVC has strong resistance to oxidizing agents, reducing agents and strong acids. However, it can be corroded by concentrated oxidizing acids such as concentrated sulfuric acid and concentrated nitric acid, and it is also not suitable for contact with aromatic hydrocarbons and chlorinated hydrocarbons.
Q:What are the disadvantages of a rubber roof?
The rubber roof house is very hot in summer because the rubber is airtight and airtight.
Q:How do ordinary NBR and EPDM materials differ?
Three EPDM (EPDM) is a non conjugated diene copolymer of ethylene and propylene and a small amount of an ethylene propylene rubber, represented by EPDM, because of its main chain is composed of saturated hydrocarbon chemical stability, only in the side chain containing unsaturated double bond, so the ozone resistance, heat resistance, weather resistance etc. aging resistance, can be widely used in automobile parts, building waterproof materials, wire and cable sheath, heat-resistant hose, rubber belt, automotive seals etc..
Q:Process for producing rubber products
There are many kinds of rubber products, but the production process is basically the same. The basic process of rubber products in general solid rubber - rubber as raw materials including: plastication, mixing, calendering, extrusion, molding, curing 6 basic processes. Of course, raw materials preparation, finishing, inspection, packaging and other basic processes are indispensable. The processing of rubber mainly deals with the contradictory process of plasticity and elasticity. Through a variety of techniques, the elastic rubber plastic rubber has become the addition of various additives made of semi-finished products, and then through the vulcanization has semi-finished plastic and rubber products into high elasticity and good mechanical performance.
