Product Details

Petroleum Resin C5 is thermoplastic aliphatic resin obtained from polymerizing C5 fraction derived from the by-product of thermal cracking of naphtha. It is transparent granular solid with the color of light yellow.

Petroleum Resin C9

Petroleum Resin C9 is low molecular weight thermoplastic aromatic resin produced from petroleum derived C9 fraction through thermal-polymerization technique. It is transparent flake solid with the color of yellow to light brown.

The using properties and the role of petroleum resin in different industries
A, paint, paint mainly use high softening point of C9 petroleum resin, DCPD resins, C5 / C9 copolymerized resin, paint to join the petroleum resin can increase the gloss paint, increase the film adhesion, hardness, acid and alkali resistance.
B, rubber, rubber is mainly using low softening point of C5 petroleum resin, C5 / C9 copolymerized resin and DCPD resins.Such resins and natural rubber granule has a good solubility, no significant impact on the process of rubber vulcanization, rubber with petroleum resin can have the effect of viscosity, reinforcing, softening.Especially the joining of C5 / C9 copolymerized resin, not only can increase the bonding strength between colloidal particles, but also can improve the bonding strength between colloidal particles and cord, suitable for radial tire contour requirements of rubber products.
C, adhesives industry: petroleum resin has good adhesion, the adhesive and pressure-sensitive adhesive tape with petroleum resin can improve the adhesive bonding strength, acid resistance, alkali resistance and water resistance, and can effectively reduce the production cost.
Petroleum resin, D, printing ink industry: printing inks are mainly high softening point of C9 petroleum resin, DCPD resins.Adding petroleum resin can play show color ink, quick drying, brightening effect, improve printing performance etc.
E, others: have certain unsaturated resin, can be used for paper sizing agent and plastics modifier, etc.
