TT-DHBP-101-45S-PS: Bifunctional Peroxide for Silicone Rubber Crosslinking
TT-DHBP-101-45S-PS is a 45% active bifunctional organic peroxide supplied in paste form, formulated for buyers who need a reliable crosslinking agent for silicone rubber compounding. Composite and rubber processors sourcing this peroxide typically compare it against other bifunctional peroxides on safe processing temperature and crosslinking speed before committing to a supplier.
Product Description
This product is a 45% formulation in paste form. It is based on 2,5-dimethyl-2,5-di(tert-butylperoxy)hexane, a bifunctional peroxide commonly used for crosslinking silicone rubber and other elastomer systems where a stable, high-temperature curing profile is required.
CAS Number
78-63-7
Product Application
It is a bifunctional peroxide which is used for the crosslinking of silicone rubber. Safe processing temperature is 135°C (rheometer ts2 greater than 20 minutes). Typical crosslinking temperature is 175°C (rheometer t90 about 12 minutes), giving processors a predictable curing window for molding and extrusion operations.
Why Rubber Processors Source This Peroxide Paste
Silicone rubber manufacturers, cable and wire insulation producers, and molded rubber part fabricators source this peroxide when they need a curing agent that balances scorch safety with an efficient cure rate. The 45% paste format simplifies dosing and handling compared to powder-form peroxides, which is a common reason buyers switch suppliers when standardizing a production line.
Key Handling and Processing Notes
- Active content: 45% in paste carrier for consistent metering.
- Safe processing temperature: 135°C (rheometer ts2 greater than 20 minutes).
- Typical crosslinking temperature: 175°C (rheometer t90 about 12 minutes).
- CAS number 78-63-7 corresponds to 2,5-dimethyl-2,5-di(tert-butylperoxy)hexane.
For buyers formulating silicone rubber compounds within our broader organic peroxide range, this bifunctional paste peroxide offers an alternative to powder-form curing agents where dust control and dosing accuracy matter on the production floor.
Storage and Sourcing Guidance
Organic peroxides of this type should be stored, handled, and transported in accordance with standard ASTM D20 committee guidance for plastics and elastomer raw materials, including cool, ventilated storage away from heat sources. Buyers should request a current technical data sheet before finalizing dosage in a new formulation.
Frequently Asked Questions About TT-DHBP-101-45S-PS
What is TT-DHBP-101-45S-PS used for?
It is a bifunctional organic peroxide used primarily for crosslinking silicone rubber, supplied as a 45% active paste for accurate dosing.
What is the CAS number of TT-DHBP-101-45S-PS?
The CAS number is 78-63-7, corresponding to 2,5-dimethyl-2,5-di(tert-butylperoxy)hexane.
What is the safe processing temperature for TT-DHBP-101-45S-PS?
The safe processing temperature is 135°C, with a rheometer ts2 value greater than 20 minutes at that temperature.
Which applications commonly use this bifunctional peroxide?
Beyond general silicone rubber, this peroxide paste is also suited to cable and wire insulation compounds, molded rubber gaskets, and extruded profiles where a stable scorch margin and predictable demolding time are important for production throughput. Buyers running continuous vulcanization lines often value the paste format because it disperses evenly without the dust-handling concerns associated with powder peroxides.
