The TN750 series uses 1.2–1.5% BPO (bis-2,5-dimethyl-2,5-di(tert-butylperoxy)hexane) curing agent, molded at 175°C for 5 minutes. Curing time may vary depending on product geometry.
4. Application Scenarios
Thanks to its comprehensive performance and customizable hardness, the TN750 series silicone rubber is widely used in:
- Food-grade kitchenware: such as spatulas, baking molds, and sealing lids
- Industrial seals and gaskets: for high-temperature and pressure-resistance
- Consumer electronics: including keypads for remotes, mobile devices, and wearables
- Miscellaneous molded parts: such as anti-slip pads, vibration dampers, and cushioning components
5. Packaging & Storage
The TN750 silicone rubber comes in 20kg cartons. It should be stored in a cool, dry place to maintain material integrity and prevent moisture absorption. Proper storage ensures consistent performance during production.
Conclusion
If you are looking for a general-purpose, high-performance silicone rubber that meets international safety standards, the Tianan TN750 series is a reliable choice. Whether for food-grade applications or durable industrial components, this series offers flexibility, strength, and excellent moldability.
