RTI is the abbreviation of Relative Thermal Index, which uses 6,000 to 20,000 hours of accelerated aging test results to infer the maximum temperature that a material can withstand in 100,000 hours, which is what we usually call the long-term use temperature of plastic. From UL yellow card In the RTI value, we can judge the long-term use temperature of the material.
RTI 155 °C UL yellow card certification has high requirements for high temperature performance and long-term thermal stability of materials, and the test cycle is long and costly. Therefore, the RTI certification of domestic modified polymers is still in its infancy. In 2013, the competition Long's high RTI enhanced flame retardant PET has passed the certification and has been widely recognized in the market.
PETFR1300 and PET-FR2300 are two grades of Polysialon RTI, high glow wire, high CTI flame retardant reinforced PET material.
