Product List

Aromatic-Modified Terpene Resin

YS Resin TO is an aromatic-modified terpene resin with broad compatibility with various elastomers and polymers. When used in EVA-based hot melt adhesives, synthetic rubber-based adhesives, or acrylic adhesives, it provides a well-balanced tack and adhesion profile. It also enhances moldability, damping, and grip in rubber products. Notably, YS Resin TO125, with a softening point of 125°C, is a unique product manufactured exclusively by Yasuhara Chemical. It also features a high content of renewable materials.

Note: YS Resin TO125 (125°C softening point) is exclusively produced by Yasuhara Chemical.

Terpene Phenolic Resin

Terpene phenolic resins are copolymers of terpene monomers (biomass-derived) and phenol. In addition to the broad compatibility of terpene resins, the degree of modification can be adjusted by grade, allowing compatibility with a wide range of materials from low to high polarity. These resins improve adhesion to difficult-to-bond surfaces such as polyolefins. High-softening-point grades, with their high Tg (glass transition temperature), enhance heat resistance and fixation in adhesive formulations. They also improve damping in rubber products, flowability in engineering plastics, and paintability. They are used in elastomer blends, acrylic adhesives, and epoxy-based products for property enhancement.

• Thermoplastic tackifier resin and additive for olefin modification
• Compatible with high-polarity and hard-to-bond materials, available in high-softening-point grades

Styrene Resin

YS Resin SX is a 100% styrene-based tackifier resin developed using oligomer polymerization technology. It enhances side-block reinforcement in synthetic rubber systems and improves heat resistance in synthetic rubber adhesives. Due to its high refractive index, it is also effective in modifying optical polymers. It contributes to optical properties, light resistance, and adhesion performance in acrylic and modified silicone adhesives without compromising base performance.

• 100% styrene tackifier resin
• Excellent compatibility with synthetic rubber (SIS, SBS, SEPS, SEBS) and acrylic adhesives

Hydrogenated Terpene Resin

These resins offer excellent compatibility with various elastomers and polymers. Compared to conventional resins, they provide superior color, heat resistance, and weatherability. They perform exceptionally well in premium hot melt adhesives. When used in UV-curable adhesives, they exhibit low curing inhibition and enhance adhesion and initial tack to olefins.

• Water-white color
• Excellent thermal stability and weather resistance
• Low melt viscosity in HMA formulations

Hydrogenated Terpene Phenolic Resin

This is a hydrogenated grade of terpene phenolic resin, which is a copolymer of renewable terpene monomers and phenol. In addition to the original properties of terpene phenolic resins, it offers excellent thermal and UV stability. Hydrogenated terpene phenolic resins are ideal for applications requiring high transparency and stability.

• Clear-type resin made by hydrogenating terpene phenolic resin
• Improved light and heat resistance
• Colorless, transparent, and odorless

Hydrogenated Styrene Resin

This is a clear resin made by hydrogenating styrene resin derived from pure monomers. Compared to conventional styrene resins, it has better compatibility with various elastomers and superior thermal stability, including reduced discoloration and weight loss upon heating.

• Water-white color
• Excellent weather resistance

Liquid Resin

These resins have broad compatibility with various elastomers and polymers and exhibit excellent tackiness at low temperatures.

Emulsion Resin

Nanolet is an emulsion-type tackifier developed using proprietary emulsification technology. It offers excellent mechanical and storage stability. It is compatible with a wide range of materials from natural rubber to acrylics and can improve adhesion to substrates such as metals and polyolefins depending on the application.
