- What is accelerator DPTT?
- Accelerator DPTT is a non-discoloring and non-staining accelerator. It is a very active sulfur-bearing accelerator and contains approximately 25% available sulfur. DPTT imparts unusually good heat resistance to sulfurless compounds and may be used as a primary accelerator for Hypalon and Butyl as well as an excellent secondary accelerator for EPDM.
- What vulcanizing agent is used in rubber?
- Elemental sulfur is the predominant vulcanizing agent for general-purpose rubbers. It is used in combination with one or more accelerators and an activator system comprising zinc oxide and a fatty acid (normally stearic acid). The most popular accelerators are delayed-action sulfenamides, thiazoles, thiuram sulfides, dithocarbamates and guanidines.
- Why are accelerators used in vulcanizing elastomers?
- Accelerators are added in small amounts to speed up the curing of adhesives by reducing the cure time and temperature of elastomers, particularly latex systems. The selection of an accelerator will depend on the specific vulcanizing system and curing properties.
