Product Profile
Tianan TN-7X0M silicone rubber compounds represent a class of high-performance High-Temperature Vulcanizing (HTV) elastomers specifically formulated for demanding automotive, electrical, and industrial applications. With hardness options spanning 30-80 Shore A, this series delivers exceptional mechanical resilience while meeting international compliance standards including FDA 21 CFR 177.2600 and RoHS directives.
Key Performance Advantages
1. Superior Elastic Recovery
Dynamic rebound properties exceed industry benchmarks by 15-20%, ensuring:
- Consistent tactile feedback in keypad applications (>500,000 cycles)
- Zero permanent deformation in sealing components under cyclic compression
2. Enhanced Environmental Resistance
- Anti-yellowing stabilizers maintain optical clarity after 1,000 hrs UV exposure
- Low specific gravity (1.07-1.23 g/cm³) reduces material consumption vs. conventional rubbers
3. Processing Excellence
- Optimized flow characteristics eliminate knit lines in complex molds
- Narrow shrinkage tolerance (±0.3%) enables precision molding of Class A surfaces
