Release Time:
2025-05-24
1. Molecular Structure Consistency
NMR spectroscopy reveals that KST products exhibit highly consistent peak profiles with mainstream competitors in key functional group regions (δ 1.2–4.5 ppm and 6.8–7.5 ppm), indicating an equivalent molecular backbone structure that meets the characteristics of Class I polymers.
2. Superior Physical Properties: Viscosity & Volatility
KST silicone oils combine high viscosity with ultra-low volatility. In both high-viscosity and low-viscosity categories, KST products maintain stable performance up to thermal decomposition points, outperforming competing brands in both viscosity retention and thermal weight loss control.
3. Low Benzene Content with Customizability
Based on UV spectrophotometry and standard curve calculations using the Lambert-Beer Law, KST long-chain silicone oils (e.g., KST-98, KST-101) exhibit low benzene content while maintaining excellent stability. The benzene level can be adjusted based on specific client requirements without sacrificing key properties.
4. Excellent Thermal Stability
Thermogravimetric analysis shows that KST products retain performance up to around 450 °C. While lower benzene content improves environmental and safety factors, KST’s formulation ensures thermal resistance even with modified aromatic levels.
5. Quality Consistency Comparable to Top Brands
Pilot-scale products using 0.35α-methyl styrene feedstock yield performance metrics (NMR, viscosity, TG) closely matching leading brands such as RH-8207G, WK-196, and TZ-1087.
This indicates that KST can consistently produce high-quality silicone oils comparable to global benchmarks.
