Properties and Uses of Petroleum Resins - ECOPOWER

According to the different raw materials used in its polymerization, it can be divided into five categories:

①Aliphatic resin and alicyclic resins, usually made from C5 fractions, also known as C5 resins;

②Aromatic resin, usually made from C9 fraction, also known as C9 resin;

③Aromatic hydrocarbon-aliphatic hydrocarbon copolymer resin, also known as C5/C9 resin;

④ Dicyclopentadiene resin, made from dicyclopentadiene or its mixture, also known as DCPD resin, because this type of resin contains unsaturated double bonds, also known as reactive resin.

⑤ Hydrogenated petroleum resin, generally C5 or C9 resin is reddish-brown to light yellow, and can become white or transparent after hydrogenation. The application of petroleum resin in hot sol and adhesive tape, the transparency of the resin is very important. Hydrogenation can also improve resin adhesion, weather resistance, stability and compatibility.

Petroleum resins are mainly used in coatings, adhesives, printing inks, additives, and rubber modifiers. With the continuous development of petroleum resin technology, its application fields are also expanding. C5 resin is currently the fastest growing class of petroleum resins, widely used in coatings, inks, sealing, bonding and other fields. C9 resin is widely used in paint, rubber, plastic and other fields, and its development prospect is very broad.

C5/C9 petroleum resin is a petroleum resin that has been put on the market in recent years and is more widely used. DCPD resins are widely used in the modification of petroleum resins due to their unsaturated double bonds. Hydrogenated petroleum resins are widely used in adhesives for hot soils and sanitary products due to their light color and no odor.
