103-34-4
Product name: DTDM/4,4'-Dithiodimorpholine
English alias: Rubber Accelerator DTDM
CAS: 103-34-4
Molecular formula: C8H16N2O2S2
Appearance: Off-white to light yellow powder
Package: 25kg/drum
DTDM (4,4'-Dithiodimorpholine) is a sulfur donor-type vulcanizing agent and accelerator used primarily in the rubber industry. It is known for its ability to generate a safe, non-blooming, and low-toxicity vulcanization process, making it a preferred choice in high-performance and environmentally sensitive rubber formulations.
DTDM/4,4'-Dithiodimorpholine is especially suitable for EPDM, natural rubber, SBR, and other synthetic rubbers, where it ensures excellent heat aging resistance, low compression set, and improved dynamic properties. Unlike traditional sulfur donors, it provides a more uniform cross-link structure, leading to superior mechanical strength and resilience.
The chemical formula of DTDM is C8H16N2O2S2, and it typically appears as an off-white to light yellow powder.
Number | Item | Specification | Result |
1 | Appearance | Off-white to light yellow powder | Light yellow powder |
2 | Initial Melting Point (℃) | ≥120 | 123.5 |
3 | Heating Loss (%) | ≤0.50 | 0.21 |
4 | Ash Content (%) | ≤0.30 | 0.18 |
5 | Purity (%) | ≥98.0 | 98.92 |
Conclusion | PASS |
1DTDM/4,4'-Dithiodimorpholine used as a sulfur donor vulcanizing agent in natural rubber and synthetic rubber compounds
2 DTDM/4,4'-Dithiodimorpholine offers non-blooming and low-odor curing, ideal for high-performance rubber goods
3 DTDM/4,4'-Dithiodimorpholine applied in automotive rubber parts, such as hoses, seals, gaskets, and belts
4 DTDM/4,4'-Dithiodimorpholine suitable for heat-resistant and aging-resistant rubber compounds
5 DTDM/4,4'-Dithiodimorpholine compatible with semi-efficient and efficient vulcanization systems
6 DTDM/4,4'-Dithiodimorpholine recommended for applications requiring low compression set and dynamic fatigue resistance
DTDM is considered a safer alternative to traditional thiuram and dithiocarbamate accelerators due to its low toxicity and non-nitrosamine-forming nature. It should still be handled with care. Avoid direct contact with skin, inhalation of dust, and ingestion. Use with appropriate PPE and operate in well-ventilated areas. Not classified as hazardous for transport under general regulations.
Store in a cool, dry, and well-ventilated warehouse
Avoid exposure to direct sunlight, heat, and moisture
Keep containers tightly closed and away from oxidizing agents
Shelf life: typically 12 months under proper storage conditions
DTDM is available in 25 kg fiber drums, paper-plastic composite bags, or kraft paper bags with PE liners
Customized packaging options available upon request
Ensure packaging is sealed during storage and transport to prevent moisture contamination
