Properties and uses of phenylmethyl silicone oil:
     Features of this product: low viscosity, low freezing point, good heat resistance, high relative flash point, small expansion coefficient, excellent electrical properties (corona resistance, high average withstand voltage).
     Applies to:
     (1) Filling oil for pressure signal transmission under the occasion of temperature change for various pressure transmitter instruments.
     (2) The insulating impregnating agent for large power capacitors can greatly improve the specific parameters, and has a wide working temperature range, which can completely replace chlorinated biphenyls.
     (3) It is used as isolation and anti-adhesive additive for plasma bags and infusion bags, base oil for surgical medicine, etc. It is also used for oil additives such as cosmetics, skin care, and anti-chilblain. Packaging, storage and precautions:
     1. Put it into a clean, dry and neutral tinplate can.
