Biomicelle® BN-105

Long-lasting internal antistatic agent for polyolefins and films.
BioMicelle™ BN-105 reduces surface resistivity in polypropylene and polyethylene without migration, improving ESD safety and long-term stability in plastic systems.

Biomicelle® BN-105: Pioneering Innovation from Japan

Biomicelle® BN-105 is a groundbreaking innovation from Japan, a unique synthesis of semi-polar organic boric and specific basic nitrogen compounds. This innovative compound maintains exceptional stability under multiplex Van der Waals forces, particularly when integrated with resins containing methylene bonds (-CH2-).

The superior static dissipative function of Biomicelle® BN-105 is derived from this advanced mechanism. Typically, molecular compounds bond through Coulomb energy. However, when static electricity is generated, charge transfer occurs, instantly converting the molecular compound into ion pairs, thereby initiating continuous static dissipation.

NAGASE supplies BIOMICELLE BN-105 globally for use in automotive interiors, packaging films, masterbatches, and a wide range of polymer-based applications.

Additional Information

Principle of Molecular Compound Type Antistatic Agent

Discover the innovative mechanism behind our molecular compound type antistatic agent, which differs from conventional products that rely on ionic conduction. This unique compound features a bond between nitrogen (N) and boron (B) components, creating a special structure with both negative (―) and positive (+) electrons.

Schematic diagram illustrating the internal antistatic mechanism of organic boron and nitrogen compounds neutralizing surface-generated charges within a polymer matrix.
When uniformly dispersed in a resin matrix, this molecular compound generates electric charges (static electricity) both inside and outside the resin. The adjacent molecular compounds then act immediately to neutralize and extinguish these charges, ensuring continuous dissipation of static electricity.

As a result, all charges within the matrix are eliminated, leaving no residual charge. Even when an applied voltage is introduced, the system achieves complete attenuation, reducing the voltage to 0 volts.

This type can be kneaded into various resins:
LDPE, HDPE, EVA, PP, POM, PVC, COP, COC, TPX, PA, PET, PBT, EPDM, PU, PS, SEBS, PVDF, & various rubber products, acrylic sheet, acrylic molding goods, acrylic caoting materials, silicone products.
