Akrosorb™ 29582 EGDMA (75)

Akrosorb™ 29582 EGDMA (75) by Akrochem is an efficient di-functional peroxide co-agent for the curing of most elastomeric systems. It is a 75% active dispersion of ethylene glycol di-methacrylate on synthetic calcium silicate. It is applicable in high hardness compounds (70 Shore D), that have excellent processability and better elastomeric properties (compression set resistance) than filler or plastic reinforced rubber. In this grade, less peroxide needs to be used to reach an equivalent state-of-cure of a formula using peroxide alone. In Akrosorb™ 29582 EGDMA (75) adding a higher-level additive, raises modulus, hardness and plasticize the rubber. It is advisable to use a scorch-retarded co-agent like SR 500 or 516 when using high levels of acrylate co-agents. In contrast to other co-agent types, the acrylic resin monomer is useful in all peroxide curable rubbers. In this additive, dry liquid dispersion (DLD) is a proven means of upgrading plant safety, quality and raw material control. It shows better uniformity of the mix at lower processing temperatures.
