Flame retardants, polymer co-stabilizer REOFOSTM EMPARATM

What are REOFOSTM and EMPARATM?

The quality required of flame retardants and the regulations surrounding them are becoming increasingly stringent every year.
In addition to making flame retardants less flammable, there is a growing need for safer, more environmentally friendly flame retardants in all fields. This includes household goods, construction materials, vehicle interiors and parts, electric wires, electronics parts, and industrial sheets.
Ajinomoto Fine-Techno markets a wide range of products, including REOFOSTM, a phosphate ester flame retardant plasticizer, and EMPARATM, a chlorinated paraffin flame retardant.

Phosphate esters

We provide various phosphate ester flame retardants such as REOFOSTM and flame-retardant hydraulic oil REOLUBE.

Variety Chemical name Application Appearance Kinematic viscosity (25degC)
REOFOSTM 30 Triaryl phosphate Phenol resin, PVC Clear liquid 44㎟/s
REOFOSTM 50 Triaryl phosphate PVC, Oil agent Clear liquid 50㎟/s
REOFOSTM 65 Triaryl phosphate PVC, Oil agent Clear liquid 61㎟/s
REOFOSTM 95 Triaryl phosphate PVC Clear liquid 93㎟/s
REOFOSTM 110 Triaryl phosphate PVC, Oil agent Clear liquid 120㎟/s
REOLUBE HYD-110 Triaryl phosphate Hydraulic oil Pale yellow liquid 42㎟/s (40degC)

Chlorinated paraffin, chlorinated fatty acid ester

We are the first company in Japan to have commercialized chlorinated paraffin. It is used as a flame retardant in the same applications as REOFOSTM products.
Because of its good electrical insulation properties, it is blended into wire coating as a plasticizer.
It is also used as a lubricant additive.
We also offer a lineup of chlorinated fatty acid esters.

About EMPARATM

EMPARATM is a registered trademark and the brand name of chlorinated paraffin sold by our company.
We were the first company in Japan to have commercialized chlorinated paraffin.
There are two types of EMPARATM - one is made from paraffin wax, and the other from normal paraffin.
Also, many varieties can be obtained depending on the degree of chlorination.
As flame retardants, they are used in the same applications as phosphate esters.
Because of its good electrical insulation properties, it is blended into wire coating as a plasticizer. It is also used as a lubricant additive.

Examples and Applications

EMPARATM is used in wire coating materials because of its excellent electrical insulation properties.
