Application of TCPP in PVC cables
1. Flame retardant performance
Function: TCPP is used as a flame retardant in PVC cables to effectively reduce the flammability of PVC cables and reduce the risk of fire.
Mechanism: TCPP inhibits the oxygen supply and combustion temperature during the combustion process through chemical reactions, thereby improving the flame retardant performance of the cable.
2. Addition ratio
Typical ratio: In PVC cables, the addition ratio of TCPP is generally 5%~15% (by weight). The specific ratio depends on the application environment of the cable, the required flame retardant grade and other formulation requirements.
Optimization: The addition ratio should be optimized according to the cable design standards and flame retardant test results to balance the flame retardant performance and other physical properties.
3. Performance characteristics
Good compatibility: TCPP has good compatibility with PVC and will not significantly affect the physical properties of PVC such as flexibility and electrical properties.
Low volatility: TCPP has low volatility and is suitable for long-term use in various environments without obvious volatilization or migration.
Chemical stability: TCPP maintains good chemical stability under high temperature and long-term use conditions to reduce degradation.
4. Environmental and safety considerations
Regulatory compliance: Some countries and regions have PVC There are strict regulations for flame retardants in cables, such as the European RoHS Directive and REACH regulations.
Environmental impact: Although TCPP has low toxicity and good stability, its environmental impact and safety must be considered, especially in long-term use and disposal.
5. Application areas
Construction: Used for cables in buildings to meet fire safety requirements.
Industry: Applied to industrial equipment and facilities to ensure the safety of cables under high temperature and high load.
Communication: Used for communication network cables to prevent fire from affecting signal transmission.
