Layers of protection
Our co-extruded surface protective films (SPFs) can be used to protect a wide range of surfaces, particularly screens for electronic devices and appliances, as well as construction materials and other products that need protection.
SPFs consist of multiple layers – skin, core and adhesive. It’s the adhesive layer that enables SPFs to bond with the surface that needs protection, and a typical formulation includes styreneethylene-butylene-styrene copolymer (SEBS), hydrocarbon resin (HCR) and additives.
We also supply modifiers that can be used as HCR in the adhesive layer, to open up properties such as peeling strength improvement at a lower material cost.

| Abitol™ E Hydroabietyl Alcohol | Rosin Resin | Abitol™ E resin hydroabietyl alcohol is a colorless, tacky, balsamic resin. Its tackiness and extremely pale color, combined with its solubility in common organic solvents and compatibility with resins, film-formers, and oils, have led to its use as a resinous plasticizer and/or tackifier in plastics, lacquers, inks and adhesives. Chemically, Abitol E resin is a high molecular weight, primary, monohydric alcohol derived from rosin acids that have been hydrogenated to reduce unsaturation. Abitol E resin undergoes the general types of chemical reaction common to most primary alcohols.
