The production of XPS (Extruded Polystyrene) foam boards involves processing materials at elevated temperatures. For flame retardant additives to be effective and maintain their integrity, they must possess a high degree of thermal stability. NINGBO INNO PHARMCHEM CO.,LTD. focuses on developing flame retardant masterbatches with exceptional thermal stability, a critical factor for ensuring both product performance and processing efficiency in the XPS industry.

XPS manufacturing typically occurs via extrusion, a process where polymer melts are forced through a die. This requires materials to withstand temperatures that can often exceed 200°C, and in some cases, approach 230-240°C or higher, depending on the specific processing conditions and equipment. A flame retardant additive that degrades or decomposes prematurely at these temperatures will lose its effectiveness and can also lead to processing issues, such as the release of harmful fumes or the formation of undesirable byproducts. This is where high thermal stability becomes indispensable.

Our advanced flame retardant masterbatches are formulated using chemical components and carrier resins that are specifically chosen for their resistance to thermal degradation. This ensures that the active flame retardant elements remain intact and functional throughout the extrusion process. A key indicator of this stability is the decomposition temperature, often measured by Thermogravimetric Analysis (TGA). Our masterbatches exhibit high decomposition temperatures, meaning they remain stable at the processing temperatures required for XPS manufacturing. This high thermal stability directly translates to several benefits:

1. Consistent Flame Retardancy: The flame retardant properties are preserved, ensuring reliable safety performance in the final XPS product.

2. Process Stability: Reduced risk of degradation byproducts, leading to cleaner processing and fewer defects in the foam board.

3. Product Quality: Helps maintain the desired cell structure and physical properties of the XPS foam, as the additive does not interfere negatively with the foaming process.

4. Extended Shelf Life: While masterbatches are generally stable, high thermal stability can also imply a more robust chemical structure, contributing to longer-term product viability.

NINGBO INNO PHARMCHEM CO.,LTD. understands that the demands of XPS production require additives that can perform reliably under challenging conditions.
