Key Performance Comparison of different catalyst cured silicone
| Comparison Item |
Peroxide Curing |
Platinum Curing |
| Odor / Volatiles |
Obvious silicone odor, VOC 200–500 ppm |
Odorless, VOC <50 ppm, food & medical grade |
| Transparency / Appearance |
Translucent, prone to long-term yellowing and blooming |
High transparency, non-yellowing and non-blooming long-term |
| Physical Properties |
Tensile strength 6–8 MPa, compression set ≤15% |
Tensile strength 8–12 MPa, resilience ≥95%, superior tear resistance |
| Temperature Resistance / Aging |
–40～180℃, moderate aging resistance |
–60～250℃, excellent aging and weather resistance |
| Cost |
Low (about 60–70% of platinum type) |
High (platinum catalyst cost is high) |
| Application Scenarios |
General industrial seals, miscellaneous parts, low-cost components |
Medical catheters, baby nipples, food molds, high-end seals |
