Applications:

• Vinyl: Initiator for high pressure vinyl polymerization, in combination with other peroxides of varying degrees of activity. Temperature range: 190°C - 240°C. Characteristics: Highly efficient.
• Styrene: Polymerization initiator for styrene, can be used in bulk or suspension systems. Temperature range: 100°C - 140°C. Dosage: 0.02 - 0.11 TP3T supplied. Advantages: Reduced residual monomer content in the polymer, no substitute for benzoyl tert.Butylperoxybenzoate. Recommended for use in combination with more reactive peroxy compounds such as tert-butyl peroxy-2-ethylhexanoate.
• Other Monomers: Polymerization initiator for (meth)acrylate and acrylate resins. Temperature range: 100°C - 160°C. Dosage: 1 - 3% Supplied products.
