Application of Paraffin Wax
Because rubber aging is an inevitable change, rubber antioxidants are used in the production of rubber products to inhibit the aging of products and extend the service life of products. Rubber antioxidants are divided into physical and chemical antioxidants, and paraffin wax is commonly used as physical antioxidants. This passage mainly introduces how paraffin wax plays an anti-aging effect in rubber products and matters that should be paid attention to.
Paraffin is a white, odorless waxy solid, alkane structure, and it is a mixture of straight chain paraffin, branched paraffin and ring hydrocarbons. The commonly used paraffin wax in rubber is ordinary paraffin wax, microcrystalline wax, rubber protective wax. Paraffin wax in rubber is a physical protective agent or softener, which can improve the anti-aging property of rubber and increase the flexibility of rubber. It does not participate in the reaction during vulcanization and is only dissolved in the rubber. When the vulcanization is cooled, it is in a supersaturated state and slowly migrates to the surface of the vulcanized rubber, forming a protective film that insulates against the erosion of oxygen and ozone in the air, thus playing a role in preventing aging.
Paraffin supplied by Richon has the following advantages: the protective film of paraffin is compact and uniform, and there is a certain thickness, which plays a good protective role; The protective film has strong adhesion to rubber; The protective film has a certain stiffness, that is, ductility; The protective film has the corresponding ability to resist high and low temperatures.
The migration rate of common paraffin in rubber is faster, and the protective film can be formed quickly. The migration rate of microcrystalline wax in rubber is relatively slow, and the time of forming protective film is slightly longer, and the protective effect is longer. The migration rate of rubber protective wax in rubber is between the two. The solubility of different varieties of paraffin wax in rubber is different, ordinary paraffin wax > rubber protective wax > microcrystalline wax. When the amount of paraffin exceeds its solubility, it will migrate to the rubber surface, but the amount is too much, the protective film is too thick, and it is easy to crack and fall off, but it affects the protective effect.
Richon chem is a professional Wax supplier. Our company regular export Paraffin Wax, PE Wax, FT Wax and rubber protecting wax. If you would like to know more about the product, please click on the website and contact us. We’ll share you more information.

In the rubber products and tire industry, tackifying resins provide the necessary viscosity during the processing process, so rubber products and tire companies are more concerned about the performance of rubber products themselves. However, the study of its viscosification mechanism should also be paid enough attention.
The theoretical research of Dalian Richon Chem on tackifying resins focuses on industries that use a large number of it, such as pressure sensitive adhesives, hot melt adhesives, etc., in these fields, the amount of it can be as high as 50 to 70 parts. Since hot melt adhesives and pressure sensitive adhesives are also composed of rubber and tackifying resins, the tackifying mechanism in these areas can also be applied to the rubber industry. The explanation mechanism can be divided into two aspects: on the one hand, the molecular adsorption and diffusion theory of rubber contact surface, and on the other hand, the formation theory of contact interface. The molecular adsorption and diffusion theory of rubber contact surface includes contact, adsorption, diffusion and other explanations, and finally unified as two-way adsorption and diffusion.
When two materials come into contact, the atoms and molecules in the material will interact with each other. These forces include strong forces such as chemical bonds, as well as weak forces such as hydrogen bonds and dispersion forces. In the case of materials, their viscosity is affected by dispersion, polarity and hydrogen bonding. In the case of rubber materials, polymers can be diffused and entangled upon contact, and through the diffusion of polymer molecules, the two surfaces are finally joined together. This is a good explanation for why small pieces of rubber become whole after a certain amount of time, because over time, the diffusion of the polymer continues and eventually forms a whole. The diffusion and entanglement of polymers are closely related to their relative molecular mass. If the relative molecular mass is small, the diffusion is easy, but the entanglement is low. If the molecular weight is high, the diffusion is difficult, but the entanglement occurs and the strength after entanglement is better. For areas that use less viscosifying resins, when considering the choice of viscosifying resins, it is also necessary to consider the effect of the relative molecular mass of the rubber used on the viscosity.
Dalian Richon is a professional rubber accelerators & antioxidants manufacturer and supplier in China. We can offer tackifying resin with high quality and moderate price. If you have any demand of rubber additives,please feel freely contact us.
According to the different functions and uses of carbon black, it can be roughly classified into: tire and rubber application carbon black, pigment carbon black and conductive carbon black. a.Carbon black for tire and rubber: The main use of carbon black is as a reinforcing agent of rubber, it can form a stable chemical bond with rubber molecular chain, so as to achieve the reinforcing effect. Generally, because the larger the surface area and the higher the structure of the carbon black, the more contact area with the rubber, the better the reinforcement will be. This type of carbon black is often used in tire tread to increase its wear resistance. For rubber products, the most important is the processing performance, usually the use of low specific surface area, high structure of carbon black, so that the rubber material is easy to process and has good extrusion characteristics, while maintaining a certain degree of physical reinforcement characteristics. About 70% of the world’s carbon black is used to make tires, which is the largest application of carbon black. About 20% of the carbon black is used for industrial rubber products other than tires, of which half are used for automotive components, so about 80% of the carbon black is consumed in the automotive industry, it can be seen that the carbon black industry is closely related to the tire industry and the automotive industry.

Carbon is one of the most common elements in nature, whether it is carbon itself or the compounds composed of carbon, it has a very wide range of applications. Among all kinds of carbon materials, carbon black is one of the earliest nanomaterials used by humans. It is widely used in the rubber industry, and also contributes to the application of carbon black in plastics, ink coatings and electrical conductivity
Dalian Richon chem Co., Ltd. have begun exported Carbon black since 2003, include Thailand, Maylasia, Mexico, Turkey and Egypt.
Carbon black is composed of more than 95% carbon, as well as a small amount of oxygen, sulfur, nitrogen and ash, is a kind of soot, texture is extremely light and fine black powder, so it is also known as carbon smoke. The particle size of primary carbon black particles is about 10-500nm, which is stacked by layers of molecular structures similar to stone grinding. If observed by electron microscope, it can be found that carbon black does not exist as a single particle, but is closely connected by one primary carbon black particle to form a grape string aggregate. This is the primary structure of carbon black; The primary structure will be adsorbed to each other into agglomerate due to the Van der Waals force, and finally after granulation, it is the carbon black particles visible on the market.
Method of making carbon black: Carbon black is a product obtained by pyrolysis or incomplete combustion of carbonaceous hydrogen compound as raw material. At present, the most important production method of Richon Chem is the oil furnace method of carbon black, using heavy petroleum oil such as tower bottom oil and creosote as raw materials, introducing the high temperature of 1800℃ reactor, accurately controlling the reaction parameters, producing carbon black with multiple applications and high thermal tail gas, and the tail gas can further produce steam and electricity.
Characteristics of carbon black: Since the primary particles of carbon black are stacked by many graphite-like molecules, such a multi-pore structure makes carbon black have certain surface physical and chemical properties, and makes carbon black have excellent reinforcement, coloring power and electrical conductivity, which are affected by the primary particle size, structural complexity and functional groups on the surface of carbon black particles.
Dalian Richon is a professional rubber accelerators & antioxidants manufacturer and supplier in China. We are the manufacture of carbon black. The product of high quality and low price. Our products have been exported to 76 countries. If you would like to know more about it, please click on the website and contact us.
