Applications
1. Flame Retardant
TEP is used in polymer materials, polyurethane systems, coatings, and other applications where improved flame resistance is required.
2. Polyurethane Industry
It can be used as an additive in certain PU foam and polyurethane formulations. Depending on the formulation, TEP can help improve flame-retardant performance and modify processing characteristics.
3. Plasticizer
TEP can improve flexibility and processing properties in selected polymer systems.
4. Solvent and Chemical Intermediate
Due to its good solvency, TEP is also used as a solvent and as an intermediate in chemical synthesis.
