Use Characteristics The super accelerator HiDispersion ETU-80 causes rapid and scorch-safe vulcanization of chloroprene rubber with high tensile strength, low compression set and high resilience. In CR compounds, MBT-80 and MBTS-80 sre effective as retarders for ETU-80. In other diene rubbers it serves as an activator and secondary accelerator for systems containing little or no sulfur. The vulcanizates, accelerated with HiDispersion ETU-80, show good ageing and mechanical properties. Generally, blooming does not occur.
Processing Advantages The thermoplastic, excellent compatible EPDM/EVA binder which is combined with active dispersing promoters allows much more easily and quickly incorporation and excellent dispersion in the rubber mixing. In this way, optimal activity of the effective ETU is assured.
