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..

 

3. Rubber Images:

Natural Rubber high elongation, cold resistant,  the elastic modulus and the shear modulus is low

4. Rubber Application:

Rubber elasticity, good insulation, impermeability and plasticity characteristics of natural rubber, and through the mix after appropriate treatment also has oil resistance, acid and alkali resistance, heat resistance, cold resistance, pressure resistance, wear resistance and other properties, therefore, has the widespread use, mainly used for automobile, machinery, industrial etc. industry as a shock, sealing parts.

Q:What material is silicone, please?
After the silica gel has absorbed moisture, it can be regenerated by solarization, baking and air drying.Chemical composition of silica gel desiccantSilica gel desiccant --- the main component is silica dioxide, from natural mineral by purification processing, granular or beads. As a desiccant, its pore structure (average 2A) Good affinity for water molecules. The most suitable hygroscopic environment for silica gel is room temperature (20~32) and high humidity (60~90%), which can reduce the relative humidity of the environment to about 40%.This is a absorb moisture from the atmosphere in the water, it is through the physical principle of drying the water molecule adsorbed on its structure or by chemical absorption of water molecules and change its chemical structure into another substance.Variable silica gel: used to keep the instrument and balance dry. Turn red after water absorption. The resulting silica gel can be dried and used again after regeneration. It can be dried amines, NH3, O2, N2 and so on
Q:Plastic, synthetic rubber, synthetic fiber is synthetic polymer material?
Polymeric materials: materials based on macromolecular compounds. Polymer materials are composed of compounds with relatively high molecular weight, including rubber, plastics, fibers, coatings, adhesives and polymer matrix composites. Polymers are the form of life. All living matter can be regarded as a collection of polymers.
Q:Is EVA material good for sole or good for rubber?Which is more wearable?
PHYLON (MD): two high pressure molding product is EVA, the main ingredient in running shoes, tennis shoes, basketball shoes at the end of the world, but also can be used for casual shoes outsole. Advantages: lightweight, flexible, fine appearance, good softness. Easy cleaning, hardness, density, tensile strength, elongation, tear. Disadvantages: easy to corrosion. The adverse environmental protection, high temperature easy to wrinkle, easy to shrink.
Q:What are the non combustible materials?
Hard PVC plastic flooring, cement board, wood cement board, chloroprene rubber floor etc.All kinds of flame retardant fabrics, such as flame retardantPolyvinyl chloride plastics, phenolic plastics, polycarbonate plastics, polytetrafluoroethylene plastics. Melamine、Urea formaldehyde plastics, silicone resin, plastic decorative profiles, and flame retardant fabrics
Q:What kind of materials do rubber and leather paint belong to?
In line with green printing, without any harm to human body. Good workability and good adhesion. Can mask the general defect or clip water injection.
Q:What material is good for yoga mats?
With the domestic Yoga market continues to improve, the development of the market, is not limited to several common materials, TPE or PVC NBR high-end, has begun to gradually withdraw from the market, the price is not high, a new material called out: PER material, in the 2015 Guangzhou Yoga Conference, this material is provided by the sponsor, the feeling is good, good elastic hardness can be, can be a very good foothold.
Q:What are the features of the cushion material?
In general we see the cushion it is made of rubber and rubber species more, the quality of natural rubber will be relatively good, because its forming speed is faster, and it plays the buffering effect is also very good, hot pressing cushion on the machine usually is also used in rubber the material to make the.
Q:1615 what kind of rubber is rubber?
It's a code name for a rubber plant. It's made of reclaimed rubber.
Q:What is rubber damping material, please?
A general term for polymeric materials with sound absorption, heat insulation, shock proof and other functions. Materials with larger internal friction peaks, such as polyacrylate, polyurethane, epoxy resin, butyl rubber and nitrile rubber, are often used at the service temperature and frequency
Q:How to strengthen the adhesion between rubber and metal skeleton material
The adhesion between reinforcing rubber and metal skeleton material was summarized from 4 aspects of rubber formulation system, rubber surface treatment, surface treatment of metal skeleton and selection of adhesive system.
