China is the world's largest chemical fiber production and application country. Relevant data show that in 2017, China's total chemical fiber production reached 47.14 million tons, accounting for 71% of the total global chemical fiber, firmly in the forefront of the world. And in the chemical fiber industry, the proportion of polyester fiber is the largest.
Due to the high production capacity, high load and high temperature of the polyester production unit, the quality of the heat transfer oil will directly affect the production stability of the entire polyester unit.
Polyester polycondensation process using hydrogenated terphenyl synthetic heat transfer oil for heating has become the consensus of most of the global polyester production enterprises. The chemical structure of hydrogenated terphenylene, due to the close distribution of the three six-membered rings and the stability of the benzene conjugate system, degradation products are mostly low molecular products, not easy to produce polymers, has excellent anti-coking properties, excellent thermal stability, can ensure long-term stable use below 330 ℃, in the use of long life, less replenishment characteristics, fully meet the heat requirements of the polyester polycondensation process.
Mantherm HT has been applied in many polyester enterprises such as Jiangyin Huahong, Zhejiang Dafa Gear and Changshu Hengyi Chemical Fiber.
