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.
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.
• Normal requirement of flange surface finishing which contact with 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.
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 5:What's the FOB port?
Anser:Our port are Shanghai and Ningbo usual.
Ask 6: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: Are there formaldehyde in rubber products, too?
- Yes, because formaldehyde is a very good organic solvent, so the general rubber varieties contain formaldehyde.
- Q: What is the cause of the bursting of rubber products and how should they be improved?
- There are five reasons for the bursting of rubber products: 1. forming temperature is too high, or the temperature of the upper and lower template is inconsistent. 2. the exhaust line is too open or exhaust time is too late. 3., the material quickly cooked. 4., the mold structure is irrational, there is no running trough. 5., down weight, overweight.
- Q: What is the difference between silicone rubber and silicone rubber?
- Silica gel is also called "silicon rubber" because of different fields so organic silica gel has become an indispensable tools in our lives, but also more than a silica silica aggregate, silica gel in the molding of silicone products manufacturers is a popular said polysiloxane silicone rubber is only a kind of synthetic rubber is a kind of non-toxic solid silicone silicone rubber. Because no accurate statement so that both of them are called organic silica gel, silica gel is a kind of solid crystal, by molding to produce silicone products applied to various places with liquid silicone are two production methods, such as "silicone" after the encounter them divided into organic and inorganic silica gel, silica or must be clear is polysiloxane synthetic silicon rubber, can also be understood as the silicon rubber is silicon A synthetic silicone rubber.
- Q: Why is rubber resistant to compression and wear better than metal?
- The rubber bushing is made of metal and has a flexible connection. The sheath is made of rubber
- Q: What is the difference between a thermoforming machine and an injection molding machine in a rubber plant?
- Hot pressing machine needs a forming template to process it, so there are many processes.If you shoot it, you can finish the product directly
- Q: What is the pressure on rubber products during vulcanization?
- The general principle of curing pressure is selected: soft rubber pressure should be small, hard pressure should be big pressure; thin-walled products to small, thick wall products pressure should be large; the product structure simple pressure should be small and complex structure of the pressure should be large; the mechanical properties of products requiring high pressure should be large, should be opposite some small; sulfide at high temperature, curing pressure can be smaller, lower curing temperature, curing pressure can be bigger.The size of vulcanizing pressure should be set up in the range of system pressure of vulcanizing equipment, combined with experience or through trial production, and set according to the quality of products.Usually in engineering applications, in order to increase production efficiency, within the scope of the permit
- Q: How to distinguish between rubber and polyvinyl chloride?
- 1) preparation: vinyl chloride monomer (vinyl, chloride, monomer, referred to as VCM) in peroxide, azo compounds and other initiators; or under the action of light and heat, polymerization by the principle of free radical polymerization of polymers. The vinyl chloride homopolymer and vinyl chloride copolymer are collectively referred to as vinyl chloride resins.2) properties: white powder, amorphous structure, degree of branching is small, the relative density of about 1.4, the glass transition temperature of 77~90 DEG, 170 DEG C to decompose, the stability of heat and light, at 100 DEG C or after long time exposure to sunlight, will decompose and produce hydrogen chloride, and further automatic catalytic decomposition that change, the physical and mechanical properties also decreased rapidly, in the practical application must be added in order to improve the stability of heat and light stabilizer of the.
- Q: NR natural rubber manufacturers, who knows Guangdong here, there are manufacturers, a few hair connection is OK
- Polybutadiene rubber (BR) is a cis structure by polymerization of butadiene rubber. The utility model has the advantages of good elasticity and wear resistance, good aging resistance, excellent low-temperature resistance, small heat generation under dynamic load and easy metal bonding. The disadvantage is low strength, poor tearing resistance, poor processability and self adhesion. Temperature range: about 60 DEG C ~100. Usually used in combination with natural rubber or styrene butadiene rubber. It mainly produces tyres, tread, conveyor belts and special cold resistant products.
- Q: Properties and specific uses of various rubbers
- Rubber is divided into natural rubber and synthetic rubber. Natural rubber is mainly derived from the Hevea tree. When the epidermis of this rubber tree is cut open, it will shed milky juice. It is called latex, and the latex will be natural rubber when it is condensed, washed, molded and dried. Rubber productsSynthetic rubber is made by synthetic methods, and different kinds of rubber can be synthesized with different raw materials (monomers). Such as, butadiene rubber, chloroprene rubber, styrene butadiene rubber and so on. The yield of synthetic rubber has greatly exceeded that of natural rubber, of which the largest yield is styrene butadiene rubber.
- Q: What is food grade natural rubber?
- Natural rubber obtained from natural rubber juice in a rubber tree and processed according to food safety requirements. It is used to process rubber products in contact with food products.
