Nature and use:Features: low viscosity, low freezing point, good heat resistance, high relative flash point, small expansion coefficient, excellent electrical performance (corona resistance, high average pressure).Suitable for:(1) filling oil is transmitted by pressure signal in the case of temperature change of various pressure transmitter instruments.(2) the insulation impregnating agent of large power capacitors can greatly improve the specific characteristic parameters, and can completely replace chlorinated biphenyls with a wide operating temperature range.(3) used in plasma bags, infusion bags for isolation and anti-adhesion additives, basic oils for surgical drugs, cosmetics, skin care, frostbite and other oil additives.Packing, storage and transportation and precautions:1. Put into clean, dry, neutral tin tin tin.2. The finished products are stored and transported in the storeroom which is moisture-proof, moisture-proof and sun-proof. The indoor temperature is allowed to be -40 ~ 50oC.3. The finished products are transported and stored as non-toxic and non-dangerous goods.Main technical indicators:(1) appearance: colorless to pale yellow transparent oily material, without mechanical impurities.(2) refractive index (ND25) 1.470 ~ 1.485(3) kinematic viscosity (CS25oC) :25 ~ 40(4) flash point (oC) : ≥240(5) tangent value of dielectric loss Angle (25oC, 50Hz) : ≤1×10-3(6) dielectric constant (25oC, 50Hz) :2.6 ~ 3.0(7) breakdown strength (KV/ 2.5mm, 25oC, 50Hz) :30(8) volume resistivity (ohm-cm, 25oC) : ≥1×1014
