Description

JYT-Series are high-performance single-phase perfluoropolyether coolants launched by Changzhou Jiayuan Chemical, including eight grades with boiling points ranging from 55℃ to 270℃. Colorless and transparent, they feature ultra-low pour point, excellent thermal conductivity and extremely high dielectric strength. With superior chemical inertness, they do not corrode metals or sealing materials and possess no flash point or fire point. Widely applied in precision cooling systems such as semiconductor manufacturing temperature control, data-center immersion cooling, wind-power-generation heat dissipation, high-voltage transformers and phased-array radars for high-efficiency energy-saving and long-term stable operation.

Technical Specifications

Applications

· Temperature-control heat dissipation for semiconductor lithography, etching and cleaning processes

· Single-phase immersion coolant for data centers

· Internal heat dissipation for wind-power generators and generator sets

· Insulating cooling for high-voltage transformers and phasedarray radars

· Thermal-shock testing and air-tightness testing for electronic components

Storage Conditions

Store in cool, dry and well-ventilated premises. Keep away from fire sources and heat; avoid direct sunlight. Keep containers tightly sealed. Store separately from acids and metal powders. Outdoor storage tanks shall adopt cooling measures in summer. Wear personal protective equipment during decanting and handling. Handle with care to prevent package damage. Transport along approved routes; avoid residential and densely-populated areas.

Packaging

Standard packages: 5 kg/drum, 20 kg/drum, 100 kg/drum. Tank-truck delivery or customised packaging available per customer request.
