Everything you need to know about our products and company
Heptamethyltrisiloxane is a specialized silicone compound with unique chemical properties that make it valuable across multiple industries. Known chemically as 1,1,1,3,5,5,5-heptamethyltrisiloxane (CAS No. 1873-88-7), this substance features a molecular formula of C7H22O2Si3 and a molecular weight of 222.5 . What sets this compound apart is its highly active Si-H group, which enables it to react with various high-molecular or low-molecular chemicals to form new silicone compounds through hydrosilylation processes .
The compound typically appears as a colorless, clear liquid with a boiling point of 141-142°C and a flash point of 82°F . With a density of approximately 0.82 g/cm³ and practically insoluble in water (0.033 g/L at 25°C), it possesses ideal characteristics for industrial applications . As manufacturers like Biyuan continue to produce this chemical, understanding its alternatives becomes crucial for industries facing supply chain challenges or seeking enhanced material properties.
Heptamethyltrisiloxane serves as a critical intermediate in numerous industrial processes. Its primary value lies in its ability to introduce various functional groups through chemical reactions, enabling the production of specialized silicone compounds . Major application areas include:
The reactivity of the Si-H group allows heptamethyltrisiloxane to form bonds with polyether, epoxy, amido, and long alkenyl groups, making it exceptionally versatile for chemical synthesis . This flexibility has established it as a valuable component in industrial chemistry, though alternatives are sometimes necessary due to regulatory, supply, or performance considerations.
Several factors drive industrial users to seek alternatives to heptamethyltrisiloxane. Through market analysis and customer feedback, Biyuan has identified key pain points that prompt the search for substitutes:
Regulatory challenges represent a significant concern. The chemical industry faces increasing scrutiny, with regulations like EU REACH potentially restricting certain substances . Even when a compound currently complies, future regulatory changes can impact long-term product viability. The case of methyl trimethicone illustrates this concern—after years of widespread use, it now faces potential restrictions due to bioaccumulation concerns .
Supply chain vulnerabilities have become increasingly apparent in global markets. Single-source dependency creates business risks, prompting companies to seek alternative materials with more stable supply chains. Biyuan’s approach involves maintaining diverse product lines to mitigate these risks for customers.
Performance requirements also drive substitution decisions. Specific applications may demand different characteristics than those provided by standard heptamethyltrisiloxane. Modified versions or alternative chemicals sometimes offer superior performance for specialized applications, such as enhanced temperature resistance or compatibility with specific materials.
Cost considerations remain a constant factor in industrial decision-making. While heptamethyltrisiloxane is competitively priced, application-specific alternatives may provide better value for certain uses, particularly when they enable more efficient manufacturing processes or reduce secondary processing requirements.
This specialized derivative (CAS No. 1361237-41-3) offers enhanced properties for specific applications. With a molecular formula of C15H36O4Si3, it provides different reactivity characteristics while maintaining the core silicone structure . The tetrahydrafurfuryloxypropyl modification makes it particularly valuable for applications requiring improved solubility or specific chemical compatibility. Biyuan’s research indicates this substitute shows promise in pharmaceutical intermediates and specialty chemical applications where standard heptamethyltrisiloxane may lack necessary functional groups.
This alternative (CAS No. 18044-09-2) features a molecular formula of C12H30O4Si3 and molecular weight of 322.62 . The acetoxypropyl modification enhances its properties for specific industrial processes, particularly where different reaction kinetics or solubility parameters are advantageous. Biyuan’s quality control testing has demonstrated consistent performance in polyurethane applications where precise reactivity profiles are critical.
With CAS No. 17861-60-8, this variant offers a different substitution pattern that alters its chemical behavior . It has a boiling point of 172°C and flash point of 45°C, making it suitable for applications with specific temperature requirements. The ethyl modification provides distinct chemical properties that may be preferable for certain synthesis pathways, particularly in the production of customized silicone oils for the personal care industry.
Other structural variants include 1,1,1,3,3,5,5-heptamethyltrisiloxane (CAS No. 2895-07-0), which features a different arrangement of methyl groups . Though similar in name, these structural differences translate to varied chemical behavior. Additionally, various modified trisiloxanes with different functional groups offer alternative properties that may better suit specific industrial needs.
When evaluating heptamethyltrisiloxane substitutes, several technical parameters demand consideration. Biyuan’s laboratory testing has generated comparative data to guide selection decisions:
Reactivity differences significantly impact manufacturing processes. Standard heptamethyltrisiloxane demonstrates particular reaction kinetics with various chemical groups. Alternative compounds may offer faster or slower reaction times, better selectivity, or different byproduct profiles. For instance, the 3-(3-acetoxypropyl) variant shows enhanced reactivity with certain polyether compounds, potentially streamlining production processes in specific applications.
Temperature performance varies among alternatives. While standard heptamethyltrisiloxane has a boiling point of 141-142°C , modified versions may exhibit different thermal stability profiles. Applications involving elevated temperatures require careful matching of material properties to process conditions.
Compatibility profiles differ across material systems. Some alternatives demonstrate improved compatibility with specific polymers or solvents, potentially eliminating the need for compatibility agents or process modifications. Biyuan’s application specialists can provide guidance on selecting the optimal trisiloxane derivative for particular material systems.
End-product characteristics may be enhanced with specific alternatives. Depending on the application, certain substitutes can impart superior properties to finished products, such as enhanced surface characteristics, improved durability, or specific tactile properties in personal care applications.
