The softening point of petroleum resin is one of the most important indicators to measure the performance of the resin. It depends on the relative molecular mass and is usually used as the basis for petroleum resin classification. The most commonly used softening point in industry is 90 ~ 110 ℃, and its relative molecular mass is between 1 000 ~ 1 400. The highest softening point can reach 140 ~ 150 ℃, the lowest is 20 ~ 30 ℃. Petroleum resins with a relative molecular mass below 600 are in liquid form.

Petroleum Resin C9 suppliers said that petroleum resin is very soluble in petroleum solvents, has good compatibility with rubber and other resins, and has good aging resistance.

C9 Hydrocarbon Petroleum Resin suppliers help us to understand Petroleum resin is a good compounding agent for NR and SR. When used as a reinforcing agent, blending 10 to 15 parts can increase the tensile strength and elongation at break of the rubber by 10% ~ 30%; used as a softener, after adding 5 to 10 parts, it can obviously improve the rubber mixing, and improve the plasticity and viscosity of the compound; used in Qingxi. The performance of petroleum resin and its application in the rubber industry Special compounding, further expanding the compounding amount can also improve the performance of rubber in water resistance, acid and alkali resistance and electrical insulation.

China Petroleum Resin C9 is a very promising compound material in rubber, especially in tire production. Compared with other similar materials, it has the following advantages:

① The price is cheap. The price of China C9 Hydrocarbon Petroleum Resin is generally 20% to 30% lower than that of rosin and 10% to 20% lower than the price of Gumaron resin. It can completely replace Gumaron resin and partially replace natural resins such as rosin and terpene, and reduce tire production costs.

②Multiple materials and complete performance. C9 Resin can have the functions of softening, thickening and filling.

③Non-toxic, no pollution to the environment. It can be used to appropriately replace aromatic oils suspected of carcinogenicity as rubber operating oils.

④There are many types and abundant resources. Now China's rubber industry has reached 1.5 million tons of rubber per year, of which tire rubber accounts for nearly half, and the demand for petroleum resin should be no less than 20,000 tons. The annual output of adhesives in China is 2 million tons. Among them, there are a large number of pressure-sensitive adhesives, hot-melt adhesives and sealants. Petroleum Resin C9 can be used to replace natural resins, and the number is estimated to be at least 10,000 tons.

In short, petroleum resin is an ideal compound material for the rubber industry, and should be vigorously researched and developed and actively promoted.
