Piccolastic™ A5 hydrocarbon resin is a low molecular weight, light colored, nonpolar, hydrocarbon resin derived from pure styrene monomer. Indicated for use in adhesives, coatings, plastics modification and rubber compounding, particularly as a plasticizer or softener. Using Piccolastic™ A5 in an adhesive system can improve flexibility at low temperatures. In styrenic block copolymer-based systems Piccolastic™ A5 associates strongly with the styrene endblocks, reducing melt viscosity and cohesion without greatly affecting tack and adhesion properties. Piccolastic™ A5 is compatible with EVA grades with up to 30% vinyl acetate and will improve low temperature flexibility and reduce the melt viscosity of the system.
