Carbon five resin and aliphatic hydrocarbon resin have an important position in the field of chemical production raw materials, and their upstream and downstream related products are extensive. The following will introduce the upstream and downstream related products of these two resins in detail.

1. the upstream and downstream related products of carbon five resin

1. upstream products: the main raw material of carbon five resin is the by-product of petroleum cracking process -- carbon five fraction. The C5 fraction is mainly composed of isoprene, cyclopentene, and piperylene.
2. Downstream products: Carbon five resin has good adhesion, water resistance, acid resistance, alkali resistance, heat resistance and other properties, so it is widely used in rubber, coatings, adhesives, inks and other fields. Its downstream related products are:

(1) rubber products: carbon five resin can be used as a rubber tackifier, improve the adhesive performance and processing performance of rubber, widely used in tires, tape, hose and other rubber products.

(2) Coating: Carbon five resin can be used as a film-forming material of the coating to improve the adhesion, water resistance, weather resistance and other properties of the coating, used in the fields of construction, automobile, ship and so on.

(3) Adhesive: Carbon five resin can be used as the main component of the adhesive, used in wood processing, paper processing, textiles and other fields.

2. the upstream and downstream related products of aliphatic hydrocarbon resin

1. Upstream products: The main raw material of aliphatic hydrocarbon resin is the C10-C14 fraction in the process of petroleum cracking, and the main component is n-alkane.
2. Downstream products: Aliphatic hydrocarbon resin has good adhesion, heat resistance, chemical resistance and other properties, so it is widely used in hot melt adhesive, pressure sensitive adhesive, rubber and other fields. Its downstream related products are:

(1) hot melt adhesive: aliphatic hydrocarbon resin can be used as the main component of hot melt adhesive, with fast curing, high bonding strength, good heat resistance and other advantages, widely used in packaging, shoes, automobiles and other fields.

(2) Pressure-sensitive adhesive: Aliphatic hydrocarbon resin can be used as one of the components of pressure-sensitive adhesive to improve the viscosity and heat resistance of pressure-sensitive adhesive, and is used to make various tapes, labels, etc.

In short, carbon five resins and aliphatic hydrocarbon resins play an important role in the field of chemical production raw materials, and their upstream and downstream related products are extensive, which play an important role in promoting the development of the chemical industry.
