With core strengths including low cyclic residue, narrow molecular weight distribution and low metal ion content enabled by its metal-ion-free catalyst system, linear body polycondensation technology has become an important technical route for upgrading modified silicone oils in high-end niche segments. From the production of amino silicone oils via linear bodies to avoid residual strong alkaline catalysts and effectively reduce additional triggers of thermally induced yellowing; to vinyl silicone oils synthesized from linear bodies that achieve high electronic-grade purity more easily without metal catalysts — linear body polycondensation is pushing the performance boundaries of high-end silicone oils.
It is prepared by co-polycondensation of hydroxyl-terminated silicone oil (linear body) and amino silane coupling agents under a mild catalytic system. With optimized dehydration parameters, the single-pass conversion rate of terminal hydroxyl groups can exceed 95%. The linear-body route skips the ring-opening chain extension of cyclic siloxanes, featuring a shorter reaction pathway. Proper process control can markedly suppress cyclic by-product formation and minimize side reactions. This process yields linear amino silicone oils with lower yellowing tendency compared with conventional ring-opening polymerization routes. After emulsification, the emulsion exhibits outstanding stability, endowing fabrics with excellent whiteness together with soft and smooth hand feel. Benefiting from low yellowing, high storage stability and uniform amino group distribution (attributed to the non-equilibrium nature of polycondensation), the product is widely adopted in high-end textile and personal care applications.
Vinyl silicone oil made via linear body polycondensation features low cyclic content, low volatile matter, narrow molecular weight distribution and superior batch consistency. It delivers prominent advantages in LSR liquid silicone rubber, LED optical encapsulation, electronic component potting, high-end silicone rubber raw materials, and new energy vehicle power battery potting. It effectively mitigates contact failure, optical fogging and blooming of finished articles caused by small-molecule volatiles, meeting the high-reliability requirements of premium electronics and optoelectronic devices.
Vinyl-terminated methylphenyl silicone oil leverages high molar refractivity, free radical scavenging and energy dissipation brought by phenyl units in its molecular chain. It boasts high refractive index, high light transmittance, high-temperature resistance, plus relatively good anti-yellowing and radiation resistance. Widely used in high-power LED optoelectronic encapsulation, special optical materials and aerospace radiation-resistant components, it effectively addresses the industry pain points of insufficient refractive index and easy yellowing at elevated temperatures for conventional dimethylsiloxane encapsulants.
