Silicone hoses are widely used in daily life, medical equipment and machinery. Many users ask how to make odorless silicone hoses for high-standard applications. Some smell is normal, but food and medical fields require completely tasteless products. Here are the most effective solutions.
Choose the Right Raw Materials
Use high-quality EPDM for better odor performance.
Genuine metallocene-based rubber works best.
Keep ENB content at around 9% for stable results.
This base material greatly reduces initial smell.
Select Low-Odor Compounding Agents
Carbon quality directly affects the final smell.
Low-grade carbon contains harmful residual compounds.
Always pick purified carbon to avoid strange odors.
Good additives ensure the hose stays tasteless in use.
Optimize the Vulcanization System
Use only the necessary amount of accelerators.
Choose low-temperature and long-term vulcanization.
Make sure the accelerator system reacts fully.
STT/D combinations work well for low odor.
White petrolatum is a good low-smell lubricant.
Avoid any accelerators that produce strong odors.
Add Secondary Vulcanization
Secondary vulcanization is highly effective.
It works for both sulfur and peroxide systems.
This step removes residual smells from production.
It also improves stability and safety in use.
In conclusion, these four methods help you make odorless silicone hoses. Proper materials, additives, vulcanization and secondary treatment ensure a tasteless, safe and reliable product for medical, food and high-end equipment.
