Triallyl Cyanurate [CAS: 101-37-1]

1.Specifiaction ( Viscosity[Cp(30℃)] 12.5 )

Product Name Triallyl cyanurate (TAC)

CAS No 101-37-1

Appearance Transparent liquid or Solid

Assay ≥99.0%

Melting Point ≥ ℃ 25 ℃

Color( Garde Liquid color standard) ≤ 5%

Moisture ≤ 0.4%

Toluene ≤ 0.2%

2. Properties

TAC is a trifunctional monomer which can easily polymerize especially in the presence of peroxide

catalysts. It is hydrolyzed by mineral acids under formation of allyl alcohol and cyanuric acid. Also

in strong alkaline medium it is decomposed easily.

3. Application

TAC is used as coagent in peroxide crosslinking of elastomers like HNBR, EPM, EPDM, EVA, CR,

TPE´s and of thermoplastics like PE and PVC. It can also be employed as coagent for electron

beam crosslinking of PE and TPE´s. TAC reduces cure times, it increases the crosslinking density,

leads to a lower compression set and improved aging properties. Typical products are:

- pipes and hoses

- sealings and gaskets

- damping materials

- cable coatings

- electronical components

- foams and shoe soles

- EVA encapsulating films for solar panels

4. Handling and Storage

TAC has a low acute toxicity. For handling regular personal protection equipment is

recommended (for details see our MSDS). If the material has to be remelted we recommend a

water bath with a maximum temperature of 50°C. Also drying chambers can be used, if the

temperature is controlled carefully. Store under cool (<40°C) and dry conditions. Although the

product is stabilized, we recommend the use TAC within 18 months. After longer storage times

turbidity by oligomeric material can be obtained.

5. Packaging: 200kg/Drum, 4 drums/Pallet
