Discover Einar® 201, the ageing modifier for high and consistent foam quality

The production of polyolefin foams is a delicate and complex process which requires fine-tuning and attention to detail. The high consistent quality of Einar® 201 guarantees reliable and dependable performance when PE and PP foam is conditioned after manufacturing for the release of the excessive blowing agent.

Even though additives such as ageing modifiers make up a small part of the formulation, legislation and customer demands are pushing for safer and more sustainable solutions all the way around a plastic product. Einar® 201 is food-grade and plant-based all while being highly efficient in applications like polyethylene and polypropylene foams.

Einar® 201 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® 201 when foams are produced with physical blowing agents is 0.4 - 1.5%. Loading levels in combination with chemical blowing agents are typically 0.2 - 0.5%.

Why do 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 a stable foam that will not collapse when products are conditioned to ensure the release of excessive blowing agents. An efficient ageing modifier like Einar® 201 can be used across various PE and PP types and will assist in achieving a continuously high-quality foam.
