I. Industry Pain Points: Dual Challenges of Structural Contradictions and Upgraded User Demands

In recent years, China’s organosilicon industry has witnessed a prominent contradiction of rapid capacity expansion paired with sluggish demand growth. Statistics show that the annual growth rate of organosilicon monomer capacity has exceeded 15% over the past five years, while downstream demand has only increased by 8%–10%. This has triggered price competition in the low-end market, whereas high-end products remain reliant on imports. Emerging sectors such as electronic encapsulation and new energy vehicles have seen surging demand for low-volatility vinyl silicone oil and REACH-compliant vinyl silicone oil. Nevertheless, conventional products suffer from three major drawbacks:

  • Excessive volatile content: The volatile fraction of ordinary products exceeds 1% under the 150°C/3h thermal weight loss test, which may cause light decay or signal distortion of electronic components.
  • High cyclic siloxane residues: The total content of D3–D10 cyclic siloxanes is above 500 ppm, which may precipitate and contaminate precision circuits.
  • Limited functionality: Unable to simultaneously meet multiple requirements including high viscosity, low cyclic siloxane content and sulfur-free formulation.

II. Product Definition: Technical Nature and Application Scope of Vinyl Silicone Oil

Vinyl silicone oil is a type of polysiloxane with vinyl groups (-CH=CH₂) on both terminal ends or side chains of the molecular backbone. Its core value lies in forming a three-dimensional network structure via cross-linking reactions of vinyl groups. Compared with conventional silicone oil, the active groups in its molecular structure endow it with three key properties:

  • Tunable reactivity: Vinyl content can be adjusted from 0.5% to 5%, enabling hydrosilylation reaction with hydrogen-containing silicone oil.
  • Controllable molecular structure: Fluidity and mechanical strength can be regulated by adjusting viscosity (50 cSt – 2,000,000 cSt) and molecular weight distribution.
  • Environmental compatibility: Compliant with RoHS requirements for vinyl silicone oil, with heavy metal content below 10 ppm.

Applicable Industries

  • Electronics & Electrical: LED encapsulation, thermal conduction for power modules, sensor potting
  • New Energy Vehicles: Battery module sealing, motor insulation, wire harness protection
  • Healthcare: Lubrication for medical catheters, silicone base materials for prosthetics
  • Construction & Building Materials: Toughening of structural adhesives, film formation for fire-retardant coatings
