product-520-462

Q1: What are its key characteristics?

It features excellent heat resistance, high hardness, good water and chemical resistance. It shows good compatibility with aromatic‑based polymers, while its color is darker compared with C5 aliphatic resin.

Q2: What function does C9 resin play in rubber compounding?

It acts as a processing aid and reinforcing agent. It improves hardness, wear resistance and sizing performance of rubber compounds.

Q3: What is the difference between C9 and C5 petroleum resin?

C9 is aromatic resin with better heat resistance and higher hardness but darker color. C5 is aliphatic resin, lighter‑colored, with superior tackiness and better compatibility with rubbers. Choose grades according to your requirements on color, adhesion and heat resistance.
