Rosins & Hydrogenated Rosins
|
Rosin is a naturally occurring, renewable source derived from pine trees. For centuries
man has made use of various pine species by purposely piercing the bark to collect
the oleoresin exudates that flowed from the wound. The rosin can be used in it's
original form or chemically reacted and converted to other, more stable tackifiers.
Rosin-based tackifiers are ideal to impart excellent, aggressive adhesion to almost
all polymer types, including, natural rubber, EVA, SBR, SIS, SBS and acrylates.
Rosin can be hydrogenated to provide better stability and aging also improving the
adhesive performance. Hydrogenated rosin resins are highly suited for use in APAO,
acrylic and styrene blockcoplymer based adhesives to improve the adhesion and cohesion.
Increasing the degree of hydrogenation results in improved stability and aging properties.
Three types of rosin are used for resin manufacture: gum rosin,
wood rosin and tall oil rosin,
all generated from the pine tree.
Hydrogenated rosin resins are available in two types: partially hydrogenated and
fully hydrogenated.
Terpenic resins are produced from crude sulfate turpentine extracted from the renewable
feedstock of pine trees.
