Product Description:

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.

Q:Are natural latex rubber products?
Natural latex is a milky, flowing liquid with the appearance of milk. Natural emulsion is a biological product. Because of its differences in tree species, geology, climate and other related conditions, the composition and colloid structure of natural latex are often greatly different.
Q:What are the applications of rubber airbags in the automotive field
Rubber accounts for 5% of the total weight of automotive materials, with an average of 100200 rubber parts per car, with a total number of 200500. Along with the automobile reliability, environmental protection and energy saving requirements continue to increase, and rubber materials, product structure optimization, improve the heat resistance, low temperature resistance, long aging, oil resistance, leakage resistance, long-term fatigue, and further reduce the cost has become the main topic of the development of automotive rubber. Fluorine rubber, silicone rubber, acrylic rubber and other special heat-resistant elastic body will still be the mainstream of the future direction of the development of automobile rubber.
Q:Process for producing rubber products
The 1. main raw materials of rubber products with rubber as basic material, and rubber is grown in tropical, subtropical and the rubber tree bark collected by artificial cut.2. various compounding agents are auxiliary materials used to improve some properties of rubber products.3. fiber material (cotton, linen, wool and all kinds of man-made fiber, synthetic fiber and metal materials, steel wire) is used as rubber products skeleton material, in order to enhance the mechanical strength, limit product variant. In the preparation of raw materials, the ingredients must be accurately weighed according to the formula. In order to make the rubber and the complexing agent can mutually mixing, need to process material. Rubber to 60--70 C drying room drying soft gel, gel breaking and then cut into small pieces, with a massive agent. Such as wax, stearic acid, rosin and so on to be crushed. If the powder containing mechanical impurities or coarse screening to remove liquid such as pine tar, ancient Malone needs heating, melting, evaporation and filter impurities, complexing agent to dry or easy to agglomerate, when mixing if not dispersed vulcanized bubbles will affect the quality of the products
Q:How to make rubber products keep brightness for a long time?
Keep it in the right place: ventilated, dry place, not squeezed
Q:What about the smell of smoked rubber products?
The corresponding type of rubber deodorant is one of good methods for removing it, or to reduce the degradation of various rubber acids produced in the processing or in the process of the use of alkoxy compounds, aldehydes, vinyl compounds, peroxide and sulfide odor of chemical additives, the smell if inhaled for a long time will stimulate the senses, give people uncomfortable feeling even harmful to the body, have two times of pollution to the environment, the chemical composition of different varieties of rubber and the resulting odor molecules are different,
Q:Why does rubber stink?
After vulcanization, the chemical composition of the rubber is sulfur compounds and smells bad.
Q:What is the difference between natural and synthetic rubber?
Synthetic rubber is made by synthetic methods, and different kinds of rubber can be synthesized with different raw materials (monomers).
Q:Does the fuel pipe for automobiles belong to rubber product?
If it is a diesel car, then the high pressure part of the metal pipe only, in the low pressure part of the rubber tube.
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:What is the tensile strength of silicone rubber?
Silicone rubber is a kind of elastomer with molecular backbone, -Si-O- inorganic structure and side group as organic group. Silicone rubber is a semi inorganic, saturated, mixed, non-polar elastomer.
