Petroleum Hydrocarbon resin
(C9 pyrolisis fraction)

SHORT DESCRIPTION Petroleum Hydrocarbon resin is is a low molecular weight thermoplastic hydrocarbon resin produced from aromatic petroleum-derived monomers. This product is made out of the ethylene's by-product through thermal polymerization. It's a kind of flake or granular solid with color from light yellow, amber to dark brown. It has the properties of good solubility, intersolubility, water resistance, insulation and very good chemical stability over acid and alkali. It also has a good adhesive strength and low heat conduction.
Petroleum Hydrocarbon resin (C9 pyrolisis fraction)
HS code
ADR class 4, packaging group III
USES C9 Hydrocarbon resin is used:
  • Adhesives;
  • Resinous and polymeric coatings;
  • Closures with sealing gaskets for food containers;
  • Rubber articles intended for repeated use.

It is characterized by low molecular weight distribution parameters and by high level compatibility, by excellent resistance to acids, alkalis and moisture. With good balance of flex, tear, tack and adhesion properties in polymer base, this resin is widely used in industrial paints, adhesives and rubber compounds, including SBS and EVA to improve the tack and the adhesion between rubber partials and cord.
