Creating chemical products for wide range of products
About Our Speciality Chemicals Business
Who We Are?
NISSO-PB is a liquid polybutadiene with high 1,2-vinyl content, high
reactivity, and excellent storage stability.
It is independently synthesized by Nippon Soda Co., Ltd., derived by polymerizing butadiene using the living anionic polymerization method. Because of the excellent cross-linking ability, due to unique polymer morphology it has superior water resistance, chemical resistance, electrical characteristics, mechanical strength, and heat resistance.
What We Do?
1. Versatile Industrial Applications
NISSO-PB has high affinity with olefin resins and high curing activity, making it suitable for a wide range of industrial products such as paints, adhesives, molding compounds, and elastomers. We work with manufacturers across these industries to identify the right NISSO- PB derivative for each application.
2. Functional Derivatives & Customization
Beyond the base polymer, multiple derivatives containing functional groups are available — enabling formulators to fine-tune reactivity, compatibility, and final product performance for their specific use case.
3. Technical Guidance
Our team supports manufacturers in selecting the most appropriate NISSO-PB grade and derivative — drawing on Nippon Soda’s deep polymer chemistry expertise to help solve technical challenges in formulation and processing.

So, that you can move forward with confidence.
What is NISSO PB?
How is it manufactured?
Are there different types of polybutadiene?
Butadiene can polymerize in three different ways: cis (1,4-polybutadiene), trans (1,4-polybutadiene), or vinyl (1,2-polybutadiene). Liquid polybutadiene produced by Nisso has a higher vinyl, or 1,2-polybutaidne, content versus other materials similar in structure. The high vinyl content leads to improvements in many areas of the finished product.
What is the effect of high vinyl content in polybutadiene?
When cured, formulations containing Nisso Polybutadiene offer improvements in:
- Electrical Properties: low dielectric constant (Dk), low dissipation factor (Df)
- Higher Glass Transition Temperature (Tag)
- Increased Hardness
- Increased Plasticity
- Additional Oil Resistance, Water Resistance
- Additional Acid Resistance
What types of applications does Nisso PB work for?
Nisso PB is used in many different applications across various industries. Some examples are:
- Rubber Additive: flexographic printing plates, rubber parts for automobiles, plasticizer, acid acceptor (for halogenated rubber), gaskets, packing, sealants
- Resin Additive: plasticizer, reinforcement for carbon fiber or plastic
- Coatings & Paint: leveling agent, defoamer, plasticizer
- Adhesives: for optical clear resin, optical clear adhesive, SGA(second generation acrylic adhesive), hot melt, epoxy curing, UV curing, heat curing
- Electrical Products: insulating materials, FCCL (Flexible Copper Clad Laminate), CCL (Copper Clad Laminate), solder resist, cover lay
- Urethanes: as a polyol, clear filler for optical improvements, reinforcement
