United Initiators TAPEHC tert.Amylperoxy-2-ethylhexylcarbonate 70833-40-8

Product Description::

• TAPEHC is a colorless liquid composed primarily of technically pure tert.Amylperoxy-(2-ethylhexyl) carbonate.
• This is a thermally stable monopercarbonate used as an initiator (source of free radicals) in the curing of polymers (SM), unsaturated polyester resins (UP), and crosslinking of polymers (EVA).
