Navigating the complexities of fire safety regulations is paramount for manufacturers in sectors like construction and building materials. Achieving compliance with standards such as DIN EN 13501-1, which classifies the fire behavior of construction products and building elements, requires highly effective flame retardant solutions. NINGBO INNO PHARMCHEM CO.,LTD. offers advanced Ammonium Polyphosphate (APP) based flame retardants specifically engineered to help clients meet and exceed these stringent requirements. Our commitment is to provide innovative, reliable, and compliant flame retardant additives.

The DIN EN 13501-1 standard classifies products based on their contribution to fire development, including aspects like ignitability, flame spread, heat contribution, smoke production, and flaming droplets/particles. For materials used in construction, achieving a high classification (e.g., Class A1, A2, B, C) is often critical for market access and user safety. Our APP blended flame retardants are formulated to contribute positively to these classifications. They work by employing an intumescent mechanism that significantly reduces ignitability, limits flame spread across the surface, and minimizes the release of smoke and heat. This makes them an invaluable component in creating building materials that are not only functional but also exceptionally safe.

Our range of APP-based products is particularly effective when incorporated into polymers and coatings commonly used in construction, such as unsaturated polyesters, epoxy resins, and various polymer composites. The phosphorus and nitrogen content within these APP blends promotes char formation, a stable, carbonaceous residue that acts as a thermal insulator and oxygen barrier. This charring process is a key factor in achieving lower fire classifications under the DIN EN 13501-1 testing regime. Furthermore, the halogen-free nature of our flame retardants aligns with a growing global trend towards sustainable and less toxic materials in building applications.

At NINGBO INNO PHARMCHEM CO.,LTD., we understand that successful implementation requires more than just a quality product. We provide technical support to ensure our clients can effectively incorporate our flame retardants into their manufacturing processes. This includes guidance on optimal dosage, processing conditions, and performance verification. By partnering with us, manufacturers can confidently develop products that meet the rigorous demands of fire safety regulations like DIN EN 13501-1, ensuring their materials are both high-performing and compliant. Our position as a leading supplier in China allows us to offer these advanced solutions efficiently and reliably, supporting the creation of safer built environments worldwide.
