Seamless integration, scalable & cost-efficient

KP transformed complex polymer rheology science into a practical plastic processing technology that boosts both environmental and economic sustainability. The KP Process aligns polymer molecules in the melt, triggering structural changes during flow. This results in advanced, efficient material structures that enhance performance, allowing for less material use while maintaining the same product quality.

Performance follows morphology

The smaller morphologies lead to the creation of a labyrinth effect which increases the barrier functionality of the final packaging.

Barrier performance

Smaller, evenly spread crystals in a polymer create a strong, consistent barrier throughout the material. This layout forms a labyrinth that makes it harder for gas or moisture to pass through, unlike large, randomly placed crystals that can leave gaps. The result is a reliable, high-performance barrier that outperforms materials with larger, less frequent crystals.

Thermal resistance

The uniform distribution of smaller crystals contributes to balanced thermal behaviour across the polymer structure. These smaller crystals help create a network that can distribute heat more evenly, preventing localized areas of excessive shrinkage or deformation. This consistency ensures that the material maintains its thermal resistance more evenly, unlike occasional large crystals, which may create uneven thermal responses with more susceptible amorphous regions in between.

Mechanical Strength

Smaller, well-distributed crystals support consistent mechanical strength by reinforcing the PET material evenly throughout its mass. This prevents stress concentration points that can develop when only a few large crystals are present, which could leave the surrounding amorphous areas prone to compression or collapse under load. The uniform crystalline structure provided by smaller crystals ensures that the material can withstand mechanical stresses more evenly, reducing the risk of localized failure and improving overall resilience.

Characterization methods

Our comprehensive Characterization Platform provides in-depth analysis of polymer morphology at every stage of processing, always comparing against industry standards.

This ensures that "Morphology Follows Rheology" and guarantees the consistent performance of our KP processing technology in industrial applications. By collaborating with top global experts, we validate results objectively and maintain clear, unbiased insights.
