Stabaxol P is a high-performance hydrolysis stabilizer developed.
Stabaxol P is designed to enhance the durability and lifespan of polymer products by protecting them from hydrolytic degradation.
Stabaxol P is particularly effective in polymers susceptible to moisture-induced breakdown, such as polyesters and polyurethanes.
Stabaxol P is a high-performance, solid aromatic polycarbodiimide-based stabilizer developed.
Stabaxol P functions primarily as an antihydrolysis agent to extend the service life of polyester- and polyurethane-based materials that are prone to degradation when exposed to moisture, elevated temperatures, and acidic environments.
Stabaxol P is particularly suited for applications requiring long-term hydrolytic stability, especially under harsh processing and end-use conditions.
Its solid form makes Stabaxol P ideal for high-temperature compounding, extrusion, and rubber processing operations where liquid stabilizers may be impractical or difficult to dose accurately.
Stabaxol P is especially beneficial in outdoor, high-humidity, and heat-prone environments, where maintaining mechanical integrity and appearance is critical over extended periods.

Stabaxol P is used for powder processing when mixing in granules and drums such as TPU, PET, PBT, PA, or when rolling and mixing with PU rubber.
The usage amount of Stabaxol P is about 0.5-2.5 parts per 100 parts of finished products.
Depending on the acid end group content and humidity content of the polymer to be stabilized as well as the stabilizing effect to be obtained, it is recommended to use 0.5 - 5.0 weight-% Stabaxol P to process millable PUR rubbers and 0.5 - 2.5 weight-% in case of polyesters, polyamides, thermoplastic polyurethanes.
The most suitable dosage depends on the requirements to be met and should always be ascertained in preliminary trials.
Trials have provided proof that by addition of 3 weight-% of Stabaxol P in millable polyurethanes, hydrolysis resistance is increased by 5 times compared to unprotected material.
The addition of merely 2.0 weight-% Stabaxol P to PET increases the life time of the latter by 3 - 4 times.
Stabaxol P improves hydrolysis resistance in hot casting systems and shoe sole applications.
Stabaxol P is used to increase durability and stability in humid conditions.
Stabaxol P is used to increase longevity and performance in applications exposed to moisture.
Stabaxol P may be processed preferrably by way of separate feeding or alternatively by direct incorporation as a dry blend.
Stabaxol P is available in Masterbatch form too, various types based upon the corresponding polymers, and thus offering the advantage of much more easier handling in respect of dosage and homogenizing.
Stabaxol P may be processed on any unit suitable for polyester and polyamide processing which provides sufficient dispersion of the neat material in the polymer.
In respect of the extruder equipment, experience showed that Stabaxol P is advisable to use a twin-screw extruder equipped with a L/D ratio > 38.
Appropriate cooling of the feeding zone is recommended to avoid particle accumulation in the feeding area.
At processing temperature, traces of volatile matters can escape which may temporarily cause irritation of skin, eyes and respiratory passages.
It is highly recommended to provide adequate local ventilation at all places where Stabaxol P stabilized products are exposed to temperatures exceeding 200 °C (392°F).
In particular, Stabaxol P is necessary to avoid direct contact with liberated vapours.
A homogeneous incorporation of Stabaxol P in polyurethane rubber does normally not present any difficulties as the actual temperature of the compound processed on the roll exceeds that of the softening point of Stabaxol P.
Stabaxol P is widely used in: Automotive and transportation (e.g., pipes, cable insulation, gaskets), Electrical and electronics (e.g., connectors, housings), Textiles and fibers (e.g., PET fibers, PBT yarns), Consumer goods (e.g., shoe soles, sports equipment), and Construction and packaging (e.g., films, sheets, profiles).
Stabaxol P products are primarily used as anti-hydrolysis agents in various polymer systems.
Polyester Polyurethanes: Stabaxol P enhance hydrolysis resistance in hot-cast systems and shoe-sole applications.
Thermoplastic Polyester Polyurethanes (TPU): Improve durability and stability under humid conditions.
Polyester Polyurethane Adhesives: Increase longevity and performance in moisture-exposed applications.
Polyester Polymers (PET, PBT, TPE): Extend service life by enhancing resistance to hydrolytic degradation.
Polyamides: Prevent degradation due to moisture, maintaining mechanical properties.
Incorporating Stabaxol P into these materials can significantly extend their service life.
For example, adding 2.0% by weight of Stabaxol® P 100 to PET can increase its lifespan by 3 to 4 times.
