China C9 Resin Introduction:
Petroleum Resin C9 is a kind of light yellow granular thermoplastic petroleum resin. It is mainly produced from carbon nine distillate, which is a by-product of the ethylene plant.
A special production process,a thermoplastic resin produced through processing, polymerization,distillation and other processes.It is not a high polymer, but a molecular weight between 300-3000 oligomers. Petroleum resins are generally not used alone, but as accelerators, modifiers, modifiers and other resins.
C9 Hydrocarbon Petroleum Resin Features:
1. It has the characteristics of low acid value, good miscibility, water resistance, ethanol resistance and chemical resistance;
2. It is chemically stable to acids and bases, and has the characteristics of good viscosity and thermal stability.
Rubber: Petroleum resin is an additive for natural synthetic rubber. It can improve the molding operation and increase the hardness and elasticity of the product. Because of improving the strength and aging resistance of rubber, this resin is particularly suitable as a softener for SBR rubber, used in the production of rubber tubes, V-belts and tires.
SBR is the abbreviation of Polymerized Styrene Butadiene Rubber. Styrene butadiene rubber is the backbone product of the rubber industry. It is the largest general synthetic rubber variety and one of the earliest synthetic rubber varieties to achieve industrial production.
According to the polymerization process, styrene-butadiene rubber is divided into emulsion polystyrene-butadiene rubber (ESBR) and solvent-polymerized styrene-butadiene rubber (SSBR). Compared with the solution-polymerized styrene-butadiene rubber process, the emulsion polystyrene-butadiene rubber process is more advantageous in terms of cost savings. About 75% of the production capacity of the global styrene-butadiene rubber plant is based on the emulsion polystyrene-butadiene rubber process. Emulsion polystyrene butadiene rubber has good comprehensive performance, mature technology and wide application, and its production capacity, output and consumption occupy the first place in styrene butadiene rubber. Oil-filled styrene-butadiene rubber has the advantages of good processability, low heat generation, and good low-temperature flexibility. It has excellent traction performance and abrasion resistance when used in tread rubber. After oil-filled, the plasticity of the rubber is enhanced and it is easy to mix. Can reduce costs and increase production. At present, the world's oil-filled styrene-butadiene rubber accounts for about 50-60% of the total production of styrene-butadiene rubber.
