With the official implementation of the "T/FSI 128—2023 Group Standard for Octaphenylcyclotetrasiloxane" by the China Fluorosilicon Organic Materials Industry Association in 2024, the quality control and production process of this product have entered a standardized stage. Previously, octaphenylcyclotetrasiloxane's high price due to its difficult synthesis and complex purification limited its widespread application. Now, through optimizing the hydrolysis-condensation method and recrystallization process, domestic manufacturers have achieved stable ton-level production.

The key to industrial production lies in controlling by-products and improving yield. High-quality products must meet a purity of ≥99.0% and ensure a narrow melting point range (203–205°C), which directly affects the performance consistency of downstream materials. Currently, chemical companies in Shandong and other regions use 25kg cardboard drums for sealed packaging, which is both moisture-proof and convenient for logistics. Since it is not classified as a hazardous chemical, it can be transported via conventional land and sea transport, greatly reducing supply chain costs.

This progress has enabled octaphenylcyclotetrasiloxane to move beyond small-scale research and development and be widely used in electronic potting compounds, high-temperature coatings, and specialty silicone rubbers. In the future, with the increasing demand for weather-resistant materials from industries such as new energy and semiconductor packaging, the market space is expected to continue to expand.
