Peroxide dispersions.

Two peroxide dispersions, DCP 70 and DBDB 60, have been introduced by the company. DCP 70 is a 70% active dispersion of dicumyl peroxide. It is used as a high temperature catalyst in the rubber and plastics industries. Compounds containing DCP 70 normally are processed at temperatures up to 250[degrees]F and can be cured at temperatures above 300[degrees]F. It is on a 30% proprietary binder. DBDB 60 (a,a'-bis(tert-butylperoxy)diisopropylbenzene) is a 60% active dispersion of DBDB. It is said to be a highly efficient scorch-resistant low odor peroxide with a wide use application area as a vulcanizing agent for elastomers and plastics. The scorch resistance of DBDB 60 is said to make it useful for transfer, injection and rotational molding applications. It also permits compounds to be extruded at higher rates. It is on a 40% proprietary binder. (Struktol Company of America, 201 E. Steels Corners Rd., P.O. Box 1649, Stow, OH 44224-0649)
