Atofina Chemicals Inc. has added two novel scorch protection technologies that can be applied to all peroxide grades. Luperox SP (scorch protected) provides good scorch protection and does not cause any loss of crosslinking density. In a standard EPDM compound, scorch time measured at 125°C is three times longer than the traditional Luperox F40, the firm said. Luperox CST (controlled speed technology) combines scorch protection with the added benefit of a reduction in curing time, while retaining identical crosslinking density. Luperox F-CST combines a 300-percent enhanced scorch time with a 20-percent reduction in curing time, Atofina said. For more information, visit www.AtofinaChemicals.com.
