Product Description

Liquid Polybutadiene (1,2-LPB), a type of liquid synthetic rubber, is a high-performance liquid rubber widely used as a reactive plasticizer, crosslinking agent, and polymer modifier in rubber, adhesives, coatings, and electronic materials.
It features high 1,2-vinyl content, low molecular weight, and excellent compatibility with various diene-based elastomers.

Key Features & Advantages

High 1,2-Vinyl Structure – Provides superior reactivity, allowing easier crosslinking with peroxide or sulfur systems.
Low Viscosity – Ensures excellent processability, improving compound flow and uniform mixing.
Low Tg – Enhances flexibility and elasticity at low temperatures.
Excellent Compatibility – Serves as a reactive modifier for EPDM, SBR, NBR, and NR rubbers, improving crosslinking density, flexibility, and low-temperature performance while reducing compression set.
Outstanding Electrical and Weather Resistance – Suitable for high-durability elastomers.
Non-Migrating Reactive Plasticizer – Chemically bonds within the polymer network, ensuring long-term stability.
Low Dielectric Constant – Significantly reduces signal loss, ideal for electronic and high-frequency applications.

Applications of Liquid Polybutadiene

Rubber Modification
1. Used as a reactive modifier for EPDM, SBR, NBR, and NR rubber compounds.
2. Improves crosslinking density, flexibility, and low-temperature performance while reducing compression set.
Adhesives & Sealants
1. Enhances adhesion strength, elasticity, and chemical resistance in polyurethane, epoxy, and silicone-based adhesives.
Coatings & Compounds
1. Acts as a binder or reactive resin in solvent-based coatings, providing superior flexibility, gloss, and impact resistance.
Specialty Polymers
1. Ideal as a base resin or modifier for thermosetting systems, thermoplastic elastomers, and electronic encapsulants.
5G Telecommunications

Due to its low dielectric constant and excellent electrical properties, it can be applied in high-frequency communications, 5G devices, semiconductor packaging, and related flexible circuit materials (CCL/FCCL).
