When selecting flame retardants for polypropylene (PP) and other polyolefin applications, two critical performance metrics that often influence the choice are smoke emission and mold corrosion. NINGBO INNO PHARMCHEM CO.,LTD. is proud to offer advanced flame retardant additives that excel in these areas, providing manufacturers with enhanced safety, improved processing efficiency, and higher quality end-products.

Low Smoke Emission: A Safety Imperative

In the event of a fire, the production of smoke can be as dangerous, if not more so, than the flames themselves. Dense smoke can impair visibility, making evacuation difficult and posing significant respiratory hazards. Our flame retardant additives are specifically formulated to minimize smoke generation when exposed to heat or fire. This is often achieved through the use of synergistic formulations that promote char formation. This char layer acts as a barrier, containing the combustion process and reducing the release of smoke particles into the environment. This characteristic is particularly vital for applications in enclosed spaces, public transport, and electronics, where occupant safety is paramount. Achieving a low smoke profile is a key differentiator for our advanced chemical compounds.

Minimal Mold Corrosion: Enhancing Processing Efficiency

The processing of plastics, especially through techniques like injection molding and extrusion, involves high temperatures and shear forces. Some flame retardant additives, particularly those containing certain halogens or aggressive chemical components, can lead to corrosive byproducts that attack processing equipment, such as molds and extruders. This corrosion can result in:

  • Increased maintenance costs due to the need for frequent equipment repair or replacement.
  • Downtime, leading to production delays and reduced output.
  • Degradation of mold surfaces, which can affect the surface finish and dimensional accuracy of the final product.

Our range of flame retardants is engineered to exhibit minimal mold corrosiveness. By utilizing carefully selected chemical systems, we ensure that the processing of your PP compounds is smoother and more efficient. This translates directly into lower operational costs and higher productivity for manufacturers. The ability to use these additives without significantly impacting tooling lifespan is a major advantage, especially when considering the overall buy price and return on investment.

Synergy for Superior Performance

The low smoke and minimal corrosion benefits are often linked to the overall sophisticated formulation of our flame retardants. These additives typically incorporate synergistic combinations of phosphorus, nitrogen, and sometimes bromine. This approach allows for a lower overall additive percentage to achieve high flame retardancy (like UL94 V0), which in turn contributes to the desirable processing characteristics. The focus is on creating high-performance materials that offer a comprehensive solution, addressing fire safety, environmental concerns, and manufacturing efficiency simultaneously.
