The "HSU Series" is a clear white thermoplastic resin made through the hydrogenation and polymerization of recycled materials. It has excellent heat resistance and good compatibility with basic polymers such as ethylene-vinyl acetate (EVA) and styrenic block copolymers (SBC), and is mainly used in hot melt adhesive tackifiers (HMA), hot melt adhesives (HMPSA), and solvent-based adhesives (SBPSA). [Applications] ■ Hot melt adhesive tackifiers (HMA) ■ Hot melt adhesives (HMPSA) ■ Solvent-based adhesives (SBPSA), etc. *For more details, please download the PDF or feel free to contact us.

• Other polymer materials

Our company handles "C9 series hydrocarbon resins," which are produced from petroleum-derived C9 fractions using catalytic polymerization techniques, characterized by low molecular weight, thermoplasticity, and aromaticity. These resins are pale yellow solid granules with excellent solubility, mutual solubility, water resistance, retention, adhesiveness, and thermal conductivity against acids and alkalis. Additionally, they dissolve in coal tar, esters, turpentine oil, and vegetable oils, are insoluble in alcohol solvents, but partially dissolve in petroleum solvents. 【Applications】 ■ Adhesives ■ Coatings ■ Inks ■ Rubber, etc. *For more details, please download the PDF or feel free to contact us.

• Other polymer materials

We handle "C5 hydrocarbon resin," which has good compatibility with EVA, SIS, SBS, NR, CR, SBR, and other polymers, and is soluble in aromatic and aliphatic hydrocarbon solvents, ketone solvents, and chlorinated solvents. This product is a pale yellow, solid granule or flake resin with low odor, high heat resistance, and antioxidant properties, and can enhance the adhesive strength of hot melt adhesives and other adhesives. Additionally, we can customize production upon request, so please feel free to consult us if you have any needs. 【Applications】 ■ Hot melt adhesives ■ Adhesives, etc. *For more details, please download the PDF or feel free to contact us.

• Other polymer materials

We handle "DPR Potassium Soap," which is produced by the reaction of dehydroabietic acid with sodium hydroxide and potassium hydroxide. It is used as an emulsifier in the emulsion polymerization of SBR, neoprene, NBR synthetic rubber, and ABS plastic, enhancing the tackiness and flexibility of synthetic rubber, as well as improving heat resistance and abrasion resistance. Additionally, it is used as an emulsifier in water-soluble oils for solvent cleaning and metal cleaning. 【Packaging】 ■ 200kg drum (※ Requires indoor storage, strict prohibition of heat and open flames) *For more details, please download the PDF or feel free to contact us.
