Everything you need to know about our products and company
Vinyl-terminated silicone fluids are critical components in industries ranging from electronics to construction, where purity directly impacts performance and product longevity. Detecting impurities in these materials requires a combination of advanced analytical techniques and rigorous quality protocols. Below, we explore proven methods to uncover contaminants, ensure compliance with industry standards, and select high-performance solutions like Biyuan’s premium-grade products.
Impurities often originate from raw materials, manufacturing residues, or storage conditions. Common contaminants include:
GC is indispensable for identifying volatile impurities like unreacted monomers. By separating components based on volatility, GC provides quantitative data on residual vinyl groups or low-molecular-weight oligomers. This method ensures compliance with viscosity specifications (e.g., 100–1000 cSt grades) critical for applications like release agents or encapsulation materials .
NMR analyzes molecular structure to detect structural defects or side reactions. For vinyl-terminated silicones, NMR confirms the degree of functionalization and identifies anomalies such as branching or incomplete polymerization. This non-destructive technique is vital for high-purity applications in medical devices or aerospace .
FTIR identifies functional groups and detects oxidation (e.g., carbonyl peaks) or hydrolysis products. By comparing sample spectra to reference standards, FTIR verifies chemical integrity and screens for contaminants like peroxides or moisture-induced degradation .
Techniques like ICP-MS or AAS quantify trace metals (e.g., Fe, Al) that compromise thermal stability. Elemental analysis is critical for industries requiring ultra-pure silicones, such as semiconductor manufacturing or pharmaceutical coatings .
Scanning Electron Microscopy (SEM) combined with Energy-Dispersive X-ray Spectroscopy (EDS) maps surface contaminants (e.g., silica particles, organic residues) and analyzes their elemental composition. This method is ideal for detecting particulates in high-viscosity fluids used in electronics encapsulation .
When selecting a supplier for vinyl-terminated silicone fluids, consider these factors:
For industries demanding reliability, Biyuan’s vinyl-terminated silicone fluids deliver consistent performance, reducing risks of premature curing or thermal degradation.
