C-5 Aliphatic Hydrocarbon Resins

 Aliphatic Resins (C5) are generally polymers of monomers with five carbons and basic C5 aliphatic resins have light yellow to light brown color (Gardner between 1.5 – 6 ).

To polymerize the liquid C5 feedstock to a hard resin a Lewis acid catalyst and carefully selecting temperature and pressure is used to get the desired softening point and molecular weight.

Since C-5 Resins are Aliphatic based so they can find their greatest utility as tackifiers for predominantly aliphatic polymers such as styrene-isoprene-styrene block copolymers, styrene-ethylene butylene-styrene block copolymers, amorphous polyolefins, polyethylene, butyl rubber, EPDM ( Ethylene Propylene Diene Monomer,)rubber, natural rubber and petroleum waxes  and also they are used in producing pressure sensitive adhesives tapes and labels, hot melt adhesives for nonwoven product assembly, modified wax compounds, hot melt road marking compounds, rubber compounding, and paint and coatings applications.
