Meeting the B1 grade fire resistance standard is a critical requirement for many fabric applications, especially in public spaces, commercial furnishings, and specialized apparel. This demanding certification signifies a high level of fire safety, and achieving it often relies on advanced chemical solutions. Ammonium Polyphosphate (APP II) is a leading halogen-free flame retardant that empowers fabrics to meet and exceed B1 grade specifications. NINGBO INNO PHARMCHEM CO.,LTD. is a dedicated APP II ammonium polyphosphate supplier for textile manufacturers seeking these advanced solutions.


APP II, particularly in its Mflam AP230S form, operates through an intumescent mechanism, creating a protective char layer when exposed to heat. This char effectively insulates the fabric, reducing flame spread and minimizing smoke emission—a crucial factor for B1 compliance. Its phosphorus and nitrogen-based chemistry ensures low toxicity and an environmentally friendly profile, distinguishing it from traditional halogenated alternatives. Our APP II ammonium polyphosphate textile applications are proven to deliver superior results.


Manufacturers looking to enhance their fabric's fire resistance can rely on APP II's excellent water resistance properties and high thermal stability. These characteristics ensure the longevity and effectiveness of the flame retardant treatment, maintaining the B1 grade even after repeated use or cleaning. For those seeking to buy ammonium polyphosphate flame retardant powder to meet specific fire safety standards, NINGBO INNO PHARMCHEM CO.,LTD. offers consistent quality.


NINGBO INNO PHARMCHEM CO.,LTD. provides comprehensive support to textile companies in formulating and applying APP II to achieve desired fire safety ratings.
