Product Description

Brief  introduction

Tricresyl phosphate is a mixture of three organophosphate isomers .In general ,

it is colorless and transparent oily liquid .It can  dissolve in Toluene ,Methylene

chloride ,Methyl ethyl ketone ,Methanol ,insoluble in water

Application

This product is an important flame retardant plasticizer for vinyl resin and nitrocellulose ,

used in the paint film can increase the flexibility, it has excellent intermiscibility,

used in synthetic rubber, PVC, polyester, polyolefin and soft polyurethane foam plastics

as flame retardants. This product can give high polymer good abrasion resistance,

weatherability, mildew resistance, radiation resistance and electric properties.

Can also be used as a gasoline additive, lubricating oil additive and hydraulic oil

Main production process

Mixed cresol reacts with phosphorus trichloride to produce tricresyl phosphite,

which then reacts with chlorine to produce tricresyl phosphate dichloride, which

is then hydrolyzed to obtain tricresyl phosphate.

Packaging and Storage

Package:   Once the TCP has been produced and refined, it is packaged into

suitable containers, such as  Galvanized drums(200kg or 230kg)

Storage:   Store at room temperature, away from direct sunlight

Inspection process

1.  Incoming inspection:  The main raw materials,  are inspected for their content, appearance and

other main properties.

2. Feeding inspection:  The principle of raw material feeding is first-in-first-out, and the appearance

of the main raw materials is randomly inspected according to whether there is a big change in the

storage conditions before feeding.

3. Batch sampling in the production process:  During the production process, the main indexes of

each batch of products: content and acid value will be examined three times in different time periods.

4. Storage Inspection:  Each batch (10 tons) is inspected before storage.

5. Outbound inspection:  According to the quantity demanded by customers, the products will be

sampled and inspected.

6. Pre-shipment inspection:  According to customer’s requirement, third party inspection can be

carried out on the products before shipment.
