Why you need ageing modifiers

Polyethylene and polypropylene foams are very popular and widely used packaging materials. They are resilient, return to form after compression, and provide effective cushioning and security where needed. It is these characteristics, combined with their versatility and customization possibilities, that make them so useful in many applications.  

Ageing modifiers are used to ensure the production of high-quality foam and provide crucially important functionality to guarantee stable foam that will not collapse when products are conditioned to ensure release of excessive blowing agent. An efficient ageing modifier like Einar® 207 can be used across various PE and PP types and will assist in achieving a continuously high-quality foam. 

Ageing modifiers for PP and PE foams

  • Einar® 207

    Einar® 207 is a plant-based, food-grade ageing modifier additive well suited for use in polyolefin foams. This high-quality GMS is a key part of any polyolefin foam, where consistency and performance are top priorities.  

    A typical loading level of Einar® 207 when foams are produced with physical blowing agents is 0.4 - 1.5%. Loading levels in combinations with chemical blowing agents are typically 0.2 - 0.5%. 

    • A distilled monoglyceride made from fatty acids and glycerol, based on a blend of palm and rapeseed oil
    • Ensures high foam quality
    • No stress cracking of electronic components
    • Efficient release of excessive blowing agents, preventing foam collapse
    • Can be used for all PE and PP grades by adjusting the dosage level
    • High heat stability and low volatility
    • Available in powder and pellet form
