We supply TEP in various packaging options: IBC drums (1200kg/1000kg) and galvanized iron drums (225kg, 200kg, 170kg). Bulk orders and customized packaging available on request.
The raw materials for TEP production are phosphorus trichloride, ethanol, and sodium acetate. The resulting compound features a phosphate ester structure, contributing to its flame retardant properties.
We offer tailored packaging and logistics solutions to meet your specific production needs. Contact us to discuss your requirements.
TEP contains phosphorus, which acts as a flame retardant by promoting char formation and reducing heat release.
Yes, TEP is designed to provide stable foaming and easy processing, suitable for continuous production.
The dosage depends on your formulation; we recommend starting with 5-15% by weight of polyol and adjusting based on testing.
Yes, our R&D team is available to assist with formulation optimization.
Store in a cool, dry place away from direct sunlight. Keep containers sealed to prevent moisture absorption.
