Product Description:

1. Description of Rubber:

Natural rubber is a kind of polyisoprene as the main component of natural high molecular compound, its composition in 91% ~ 94% is the rubber hydrocarbon(polyisoprene), the protein, fatty acid, carbohydrate, ash and other non rubber substance. Natural rubber is the most widely used general rubber..


2. Main features of Oil Seal:

1) High Elasticity, According To The Formula, The Elastic Can Reach 80% Of The Maximum.

2) high elongation, the maximum can reach more than 1000%.

3) the elastic modulus and the shear modulus is low, than some rigid substances such as iron and steel and other low much.

4) cold resistant, the glass transition temperature of minus 72 degrees..

Q:What kind of rubber skid proof performance is better?
Outsole: This outsole is not common. The base material is industrial glue. It can be molded by stirring the mixer and then heating into the mold. It is soft and very slippery
Q:What is the material of rubber boots
Waterproof canvas, usually made of polyester for grey cloth material, and then made of wax oil, waterproof, mildew proof, dust-proof function canvas. With bright colors, light quality, soft and durable, high strength, tensile resistance, sunscreen, waterproof, mildew, frost resistance, corrosion resistance and so on. During use, avoid cutting, hitting and cutting with sharp objects.
Q:What chemicals are added to the wiper bar, please?
Specific formula, but also according to different types of rubber to add chemical raw materials, such as: synthetic rubber, natural rubber, silica gel formula, raw materials are far from each other.
Q:Which is better, PVC coil or TPO coil?
TPO waterproofing membrane is the use of advanced polymerization technique (EP) and ethylene propylene rubber polypropylene combined with thermal plastic polyolefin material as base material, with a polyester mesh fabric as a carcass reinforcing material, waterproof material and made of flexible sheet using advanced processing technology.
Q:What is the quantity of fluorine rubber? What is the price of fluorine rubber?
Fluorine rubber FKM has high temperature resistance, oil resistance and a variety of chemical resistance characteristics, is the modern aviation, missiles, rockets, aerospace and other cutting-edge science and technology indispensable material. In recent years, with the continuous improvement of the reliability and safety requirements of the automotive industry, the use of fluorine rubber in automobiles has also increased rapidly. Fluoro rubber FKM is a synthetic polymer elastomer with fluorine atoms on the carbon atoms of the main chain or side chain. The copolymer of fluorine rubber FKM first poly fluoro -2- -1.3- butadiene America DuPont company produced and styrene and propylene, but the performance is not better than chloroprene rubber, chloroprene rubber is outstanding, and the price is expensive, not the actual industrial value. In the late 50s, the United States Thiokol company developed a low temperature good, strong oxidizing agent two yuan nitroso fluorine rubber, fluorine rubber began to enter the actual industrial application.
Q:Which is better, oak or PVC?
On the market there are several kinds of bathroom cabinet plate, but the high-end products are mostly made of wood, because of its good waterproof performance, seepage deformation, low expansion advantages such as the existence of the mainstream trend of bathroom cabinet bathroom cabinet plate is the future.Solid wood bathroom cabinets generally choose oak as the base material is better.
Q:What is the density of polyurethane?
Hard polyurethane coating agent polyether based polyurethane foam density: 0.04 ~ 0.06g/cm3 hard polyurethane foam density: 0.03 ~ 85 0.07g/cm3 polyurethane density of about 1.2g/cm3, no filler generally around 1.1
Q:What are the thermal insulation materials for ventilation and air conditioners?
For air conditioning insulation materials at the interface of anti leakage products include: PE insulation tape, foam rubber insulation tape, PU sponge tape, etc..
Q:What does "CAF" mean in rubber material? Know more about it
Should be EPDM bar, that is, three yuan ethylene propylene rubber, the use of a wide range.
Q:Comparison of physical properties of HNBR rubber material with other rubber materials?
HNBR NBR maintain the original excellent oil resistance and heat resistance, and obtained very good (150 degrees high temperature resistant), ozone resistance, its application field has broken the traditional field of NBR, the chlorinated polyethylene, chlorosulfonated polyethylene and special rubber is also subject to certain impact. From an economic point of view, the HNBR sales price is temporarily more expensive, but still much lower than the fluorine rubber. At the same time, because of its low stiffness, good process performance and low density, more fillers can be added, and the unit volume of HNBR products is only about half of that of HNBR. Therefore, it will be a substitute for special elastomers such as fluorine rubber. Although HNBR has been produced abroad for many years, its application field is expanding constantly, and it is still blank in our country. We should develop HNBR at the right moment. According to a preliminary understanding, China's Daqing, Shengli Oilfield has more than 2000 export two wells with submersible pump in the depth of 2000 meters, pumping temperature is about 140 DEG C, such as the use of NBR to the spindle, use only a few months or even shorter period, such as the use of HNBR to the spindle, use period of up to one year or more. Nanjing rubber products factory in China needs more than HNBR30 tons per year. In the manufacture of a HNBR, the catalytic hydrogenation technology of NBR is the key technology and solution conditions for hydrogen production NBR harsh, Portland company already in this work, the rhodium recovery rate is low, the cost is relatively high. Water soluble catalyst of hydrogen and two-phase hydroformylation is separation and recovery and recycling based on noble metal catalysts, once can make the application of this kind of catalyst to polymer hydrogenation, hydrogenation can use them to carry out NBR, we have synthesized two water soluble phosphine ligands, ongoing efforts in this aspect.
