PETROLEUM RESIN

PETROLEUM RESIN


C9 PETROLEUM RESIN

Character:

C9 petroleum resin is a petroleum by-product of
pyrolysis C9 fraction which is produced by pre-treatment, polymerization and
distillation processes. It is not a high polymer but a low polymer molecular
weight between 300-3000. It has the characteristics of low acid value, good
miscibility, water,ethanol and chemical resistance, the chemical stability
against acid, the good adjustment of viscosity and thermal stability.
Generally, 9 petroleum resin is not used alone, but as promoters, regulators,
modifiers used with other resin.

Applications:

A. Paints Industry: In paint industry mainly use the high softening point of C9 petroleum
resin which can increase the gloss of paint and improve the adhesion, the
hardness and the resistance ability of acid and alkali.

B. Tire and Rubber Industry: in tire and rubber industry, low softening point of C9 petroleum resin
is mainly used which has a good miscibility with natural rubber particles, and
little affect on rubber vulcanization. Adding in rubber and tires, petroleum
resin can increase the adhesion and the reinforcement and can also play as softener.

C. Adhesives Industry:

C9 petroleum resin having good adhesion, added in the process of
producing adhesives and pressure-sensitive adhesives can improve the adhesive
bond strength, acid resistance, alkali resistance and water resistance, and
also can reduce production costs effectively.

D. Ink Industry:

In ink industry mainly use the high softening point of C9 petroleum resin
which can reach the effect of show color, quick-drying and brightening and
improve printing performance, etc.

F. others Petroleum resin
having certain characteristic of unsaturated, can be used as paper glue,
plastic modifier etc.

Use:
In the industry of adhesive
and sealant, petroleum resin plays an important role as tie resin. Our petroleum
resins are suitable to the petroleum resin of hot-melt adhesive and contact
adhesive. They have good compatibility with SIS, SBS, SEBS, SEPS, natural
rubber, synthetic rubber and EVA etc.
