JINELEC 400
JINCHEM
Product Name: Monobenzyl Toluene & Dibenzyl Toluene Insulating Liquid (M/DBT)
CAS Number: 27776-01-8, 26898-17-9
Molecular Formula: C14H14, C21H20
JINELEC 400 is made of Monobenzyl Toluene(MBT) and Dibenzyl Toluene(DBT) in a specific ratio, supplemented with an appropriate amount of functional materials. After professional degassing, dehydration and other refining processes, the product shows excellent physical and chemical properties and electrical properties. It is a special product for high-voltage and ultra-high-voltage full-film structure power capacitors, ensuring the reliability and high efficiency of the capacitors.

Transport
JINELEC 400 is not regulated by any transport regulations : road, river, ADR/RID, sea or air transport. It does not need any special labeling. It is not classified as dangerous.
Storage
JINELEC 400 can be stored in plain steel vessels. There is no risk of degradation during storage. However to avoid contamination by air which could increase the liquid conductivity and water content, it is recommended to store the product under nitrogen or under vacuum.
Fire Hazards
In case of fire reaching vessels or equipment containing JINELEC 400, the recommended extinguishing agents are : Carbonic anhydride, foams, chemical powders.
Even if the toxicity of pyrolysis products is very low (lower than for mineral oil for example), it is recommended that firemen be equipped with autonomous insulating breathing equipment, since carbon monoxide may be formed in case of incomplete combustion.
Handling
As it is generally indicated for organic products with high boiling points, breathing concentrated vapors or fumes for a long period should be avoided.
Due to the low toxicity of JINELEC 400, there is no limit value officially recommended by governmental authorities. However a concentration limit of 1000 ppm in the working atmosphere sounds sensible.
It is generally considered that there is no specific measure to be taken if the concentration in the atmosphere is lower than 0.2 times the limit value. Therefore if the concentration is above 200 ppm, a vapor aspiration system is recommended.
Contact with eyes and skin should be prevented : gloves and goggles should be worn (as well as a mask if the liquid is hot).
In case of contact, wash thoroughly with water.· In case of leakage : Do not let the product enter into drains. Contain by damming. Pump into an inert labeled emergency container. Absorb the remainder with an inert absorbent material.
Disposal
It is recommended to destroy the product by incineration : it is considered as an ordinary fuel oil.
