In the fields of silicone rubber product manufacturing and paper surface treatment, the performance of functional additives directly affects the quality and production efficiency of the final products. The product, Phenyl Hydroxy Silicone Oil 2207, launched by Anhui Aiyouta Silicone Oil Co., Ltd., has the chemical name of Hydroxyl-terminated Phenyl-Methyl Silicon Oxide-Disodium Silicate Copolymer. With its unique molecular structure design and stable physical and chemical properties, it demonstrates significant industrial value in the two core application areas of silicone rubber structure control and paper anti-adhesion treatment, providing reliable domestic additive options for related industries.


I. Core Physical and Chemical Characteristics of the Product


Product Phenyl Hydroxy Silicone Oil 2207 is a colorless transparent liquid. At 25 degrees Celsius, its viscosity ranges from 500 to 20,000 millipascal-seconds. It can provide various viscosity specifications according to different application requirements. The density is 0.98 grams per cubic centimeter. The product has active hydroxyl groups at both ends of the molecular chain, and simultaneously introduces phenyl and methyl silicone oxide units in the main chain, possessing both reactive properties and moderate spatial steric hindrance effects, enabling it to exert unique functional advantages in silicone rubber processing and paper treatment applications.


II. One of the core application areas: Structural Control Agent for Silicone Rubber Processing


During the processing of high-temperature vulcanized silicone rubber and liquid silicone rubber, silica fume, as the main reinforcing filler, has a large number of active silane groups on its surface, which will undergo physical and chemical reactions with the silicone rubber molecule chain, causing the rubber to gradually harden and lose plasticity during storage, resulting in structuralization. Product Phenyl Hydroxy Silicone Oil 2207, as a structural control agent, has active hydroxyl groups at both ends of the molecular chain, which can react preferentially with the hydroxyl groups on the surface of silica fume, effectively钝化 the active sites on the filler surface， thereby inhibiting the structuralization process and maintaining the processing fluidity of the rubber.


The inhibitory effect of hydroxy silicone oil structural control agents on silicone rubber structuralization is superior to that of methoxy silicone oil and dimethyl diethoxy silicone oil and other types of additives. It can significantly reduce the Melt Flow Index (MFI) attenuation of the mixed rubber and extend the safe storage time of the rubber. The dosage of 6 parts is sufficient to achieve the desired effect. Product Phenyl Hydroxy Silicone Oil 2207 introduces phenyl segments in its molecular structure， compared with ordinary dimethyl hydroxy silicone oil， has better spatial steric hindrance effect and compatibility with the phenyl silicone rubber system， especially suitable for high-filler or high-transparency rubber compound formulations， having less impact on the mechanical properties and transparency of the final product.


III. Another core application area： Anti-adhesion Treatment for Paper and Other Materials


Product Phenyl Hydroxy Silicone Oil 2207 demonstrates excellent performance in anti-adhesion treatment for paper and other materials due to its low surface energy. When used as an anti-adhesion agent， it can form a uniform temporary isolation layer on the paper surface， effectively preventing the paper from adhering to each other during processing， storage， and transportation.


In label base paper production， using Product Phenyl Hydroxy Silicone Oil 2207 treatment， the label paper can be easily peeled off without any adhesion phenomenon， significantly improving the production efficiency of die-cutting and labeling. In asphalt packaging paper， this product can effectively prevent the paper from adhering to asphalt， ensuring the integrity and reliability of the packaging. Additionally， the product is suitable for anti-adhesion treatment of various release paper such as box wrapping paper base paper， decoration paper base paper， etc.， and also provides the paper with certain waterproof and moisture-proof properties， maintaining the stability of the paper in high-humidity environments.


IV. Packaging， Storage and Operating Precautions


Product Phenyl Hydroxy Silicone Oil 2207 is packaged in 200-kilogram plastic drums or iron-plastic drums. The strict packaging method effectively avoids contamination of the product during transportation and storage. The product should be stored in a well-ventilated， cool， and dry place， avoiding the mixing of acids and alkalis and being away from fire sources. Under the above storage conditions and without opening， the shelf life of this product is 12 months. During transportation， it is managed as a non-hazardous product， saving transportation costs and management efforts for enterprises.


V. Quality Assurance and Industry Application Value


The product phenolic hydroxyl silicone oil 2207 has established a strict quality control system during the production process. Key indicators such as appearance, viscosity, and density are subject to full-process testing to ensure consistency and reliability between batches. With the rapid growth of downstream fields such as new energy vehicle cables, medical catheters, communication sealing components, and high-end release materials, the refined requirements for silicone rubber processing additives and paper anti-adhesion agents are constantly increasing. Product phenolic hydroxyl silicone oil 2207, with its unique hydroxyl-terminated phenolic silicone oxide copolymer structure, stable physical and chemical properties, and wide application adaptability, is providing mature and reliable domestic additive solutions for silicone rubber product enterprises and paper processing manufacturers. This helps the related industrial chain achieve quality improvement and efficiency enhancement.
