Si-APP: Flame Retardant in the Electrical Industry

Introduction: Si-APP as a Halogen-Free Flame Retardant Alternative

The electronics and electrical industry demands materials that balance high performance, safety, and environmental compliance. Traditional halogenated flame retardants, while effective, face increasing regulatory restrictions due to toxic emissions and persistence in the environment. Silane-coated ammonium polyphosphate emerges as a superior halogen-free alternative, addressing critical challenges associated with unmodified APP.

Global Flame Retardant Standards and Si-APP Compliance

Electronic components must comply with rigorous flammability and environmental regulations, including UL 94, IEC 60695, RoHS, REACH, and UL 60950. Si-APP is fully compliant with these standards, as it is halogen-free and lead-free. Its silane coating enhances thermal stability and water resistance, enabling it to meet strict flammability requirements at low loadings.

Epoxy Molding Compounds for Semiconductors

Si-APP is widely used in epoxy molding compounds (EMCs) for semiconductor packaging. It solves the “popcorn effect” caused by unmodified APP, improving dispersion and reducing water absorption. A leading semiconductor manufacturer uses it in EMCs for automotive MCUs, passing key industry tests.

PP Housings for Consumer Electronics

For polypropylene (PP) housings of consumer electronics like power banks and chargers, it formulations achieve UL 94 V-0 compliance. They maintain good processability for thin-wall molding and resist migration, with a global brand adopting them for safe, compliant products.

Wire and Cable Insulation

Si-APP ensures electrical safety in wire and cable insulation, offering advantages in TPU and PE cables. It reduces smoke emission and meets VW-1 and IEC 60332-1 standards, as demonstrated by its use in data center server cables by a major manufacturer.
