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. This results in alternating layers of filler and metal.

2.Features of Gasket :
• 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.
•  Food processing industry.
• Hot acetic and citric etc.

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.
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.

Q:Which is better waterproof performance, neoprene or silica gel?
High temperature silicone rubber is mainly used for making all kinds of silicone rubber products, while room temperature silicone rubber is mainly used as adhesives, potting materials or dies. The maximum amount of heat curing type, heat curing type and methyl silicone rubber (MQ), methyl vinyl silicone rubber (VMQ, dosage and product grades at most), methyl vinyl silicone rubber (PVMQ low temperature resistance and radiation resistance), there are other eyes of silicone rubber, fluorine rubber and so on.
Q:Is silicone good or rubber good?
Rubber is divided into natural rubber and synthetic rubber, natural rubber structure is isoprene polymer, synthetic rubber such as polybutadiene rubber, chloroprene rubber, styrene butadiene rubber. When rubber is deformed by the external force, the crosslinked rubber has the ability to recover quickly, and has good physical and mechanical properties and chemical stability.Silicone rubber is mainly composed of high molecular weight linear polysiloxane. The Si-O-Si key is the basic bond formed, mainly methyl silicon atoms connected, introduced a very small amount of unsaturated groups in side chain, intermolecular interactions, molecular spiral structure, methyl arrangement and can freely rotate outward, thus vulcanized silicone rubber has excellent resistance to high and low temperature (-100~315 DEG C). Weather, water repellent, electrical insulation, physiological inertia and other characteristics, are widely used in military, medical, industrial and agricultural production and people's daily life. Most importantly, there is no toxicity, as usual in pacifiers and breast implants.
Q:What kind of product is suitable for rubber trimmer? Where's the rubber trimmer?
Rubber products, silica gel products, special rubber products only need to have the rubber parts of the dismantling groove, and the diameter of the rubber inside the 100MM can be used as trimming machine.
Q:How can the frictional properties of rubber improve?
Because of its high elasticity and low modulus, the friction and wear properties of rubber are greatly affected by their physical and mechanical properties. The hardness of rubber is smaller, contacting with a rigid object, the real contact area is large, and the real size of the contact area is an important factor, so the friction rubber hardness, have more effect on the friction performance.
Q:What is the size of the scorch time of the rubber?
Rubber scorch characteristics usually use 120 degrees Mooney scorch time Ts said, also available vulcameter determining curing curve on the T10 or TA1, TA2 said, the scorch time and process, the rubber accelerator process conditions, the hardness of the rubber material and rubber material return use and other factors. Generally soft rubber is 10-20min; most of the stock (excluding high filling hard or high temperature 35-80min) is 20-35min; the high filling hard material is.
Q:What are the causes of chapped rubber products?
This is the aging phenomenon of rubberAging refers to the polymer materials (including rubber, plastics, fiber and so on) in the processing, storage and use of the process, due to the comprehensive effect of internal and external factors, its performance gradually deteriorated, resulting in the final loss of use value
Q:How can I remove the rubber flavor on rubber products? It smells terrible
Different types of rubber deodorant by different chemical AO and effect, which can effectively remove all kinds of rubber, including reclaimed rubber, flame retardant rubber smell in the processing and use of rubber products, improve the level of environmental protection, applicable to all kinds of rubber molding process. The utility model has the advantages of low use, high efficiency, safety and innocuity
Q:What are the common rubber products, please tell me
Generally in one hundred thousand, and even reach about million, followed by rubber is the size of the molecular weight varies. Latex extracted from rubber trees, rubber, grass, etc.
Q:Rubber products labeled Huai gum can improve wear?
Basically through the carbon black to adjust, carbon black will also be divided into a variety of, according to the degree of wear resistance will also be divided into many grades, in the rubber formula has reinforcing effect.
Q:What is food grade natural rubber?
Standard rubber, natural rubber latex concentrate only and solid and liquid substances is concentrated latex by high-speed centrifuge after processing, required special barrel plus fresh, dry rubber content is 60%; the standard is a standard solid rubber rubber good solidification, machining, drying, packaging, which according to the impurity content to several levels and it has international standards, countries also have the corresponding standard.
