Products
Viscose increasing resin is an irregular sheet or semi circular granular product made from rosin after special modification. This resin has light color, low odor, good thermal stability, and excellent oxygen resistance. It can greatly improve the adhesion of products in the application of Hot-melt adhesive, pressure sensitive adhesive and adhesive. This product is soluble in various solvents such as aromatics, fats, esters, and ketones. It can be mixed with high polymers such as EVA, SIS, SBS, NR, CR, SBR wax in any ratio.
Pentaerythritol Ester Of Rosin
Pentaerythritol ester of rosin is a type of light color granula and flake solid that made of refined gum rosin with treatment of pentaerythritol esterification. Soluble in petroleum hydrocarbons, aromatic, esters, ketones, acetic ether, acetone, gasoline etc. Insoluble in water and alcohol. Comes with light color, high softening point, thermostability, color retention, and strong adhesive force.
Glycerol ester of rosin also named glyceryl rosinate or ester gum, it’s made of gum rosin and glycerol ester with stabilizing treatment. It can be perfectly dissolved in polymers. It comes with excellent adhesivity to be widely used in various adhesive manufactures, it is light color and economic type of tackifier material.
Hydrogenated Water White Rosin Resin
Water white rosin resin is a type of polyalcohol rosin that is made of gum rosin with a series of producing process, such ashydrogenation, disproportionation and other stabilizing treatments. It comes with water-white, low odor, anti-aging and other positive features, can be dissolved well in high polymer. It’s a new-type tackifier for adhesive manufacturing.
Hydrogenated Rosin、Hydrogenated Water White Rosin
Hydrogenated rosin is one of the further processed & modified rosin, it’s made of gum rosin and PD/C catalyst, melted under high temperature and high pressure to make it hydrogenated. Hydrogenated rosin has good performance at anti-oxidation, thermal stability, light color, low brittleness, strong bonding, non-toxic and no peculiar smell. It can be widely used in manufacturing, such as synthetic rubber, adhesive, painting & coating, printing ink, paper making, electronics, soap, food and so on. In the synthetic rubber manufacturing, such a material can not only be used as emulgator, but also as plasticizer, tackifier and softener, it can substantiallyimprove the features of products.
Water-white rosin is a type of polyalcohol rosin that is made of gum rosin with a series of producing process, such as hydrogenation, disproportionation and other stabilizing treatments. It comes with water-white, low odor, anti-aging and other positive features, can be dissolved well in high polymer. In addition to adhesivemanufacturing, it can also be used as high grade solid and liquid welding flux.
Gum rosin also named greek pitch or colophony, it is a kind of natural resin that are mainly composed of various kinds of resin acids, it can be dissolved easily in many organic solvents, and has special chemical activity, it can be esterified and neutralized with carboxyl, and reacted by double-bond, disproportionated, hydrogenated and polymerized to optimize its physicochemical property. Gum rosin can be widely used in manufactures of paper, coatings, inks, rubbers, soaps, electronic industrial products, food grade ester gum, rosin ester resins etc.
