For polyethylene glycol products, what kind of drying oven is suitable? 1. Polyethylene glycol products tend to deteriorate when the temperature is above 40 degrees Celsius. 2. Currently, a double-cone dryer has been used, and it tends to stick together.

The polyethylene glycol 400 used in monocrystalline and polycrystalline silicon seems to have had iron ions removed through resin treatment, and water is removed by vacuum distillation at 120 degrees without any change in color.
