TPP (Triphenyl Phosphate) is a commonly used phosphoric ester additive known for its flame retardant and antioxidant properties. However, in some conditions, TPP may release phosphoric ester smoke and toxic gases, posing potential hazards to the environment and human health. In the applications that involving frequent contact with the human body, such as medical devices and baby products, the use of TPP-free TPU materials is required to ensure product safety and environmental friendliness. This precaution is taken to reduce any potential risks associated with harmful emissions.

The use of TPU (Thermoplastic Polyurethane) in various applications typically requires that it does not contain TPP (Triphenyl Phosphate).The exclusion of TPP from TPU applications underscores the commitment to product afety and environmental responsibility. By selecting TPU materials that are free from TPP, manufacturers and consumers can have peace of mind knowing that their products meet strict safety standards and minimize their impact on the environment. All KOSLEN TPU except the AP grade are TPP-free TPU. 

By adhering to these guidelines, TPU manufacturers KUNSUN polymer can ensure the production of reliable and eco-friendly products, while consumers can trust the quality and safety of the KOSLEN TPU-based items they use in their daily lives.
