-Product Recommendation- Low-Hydrogen Silicone Oil: The Industry's "All-Round Player" Has Arrived
It turns out that these everyday essentials all contain hidden "silicone" powerhouses! ✨You may not have heard of "low-hydrogen silicone oil," but it has already quietly infiltrated your life-from your waterproof jacket to the chip protection in your phone, it's all thanks to it! Today, let's get to know this "hidden gem" in the silicone family~
Simply put, it is a silicon material with "active hydrogen" and many "small handles" (professionally called Si-H bonds) that can react chemically.
The main chain features alternating Si-O bonds, while the side chains contain active Si-H bonds. The hydrogen content is adjustable from 0.1% to 0.8%! It exhibits both high reactivity and excellent resistance to high and low temperatures (stable from -50℃ to 200℃), and it's compatible with a wide variety of materials, boasting exceptional compatibility.
Core application areas
1. Intermediates in Silicone Product Synthesis
This is the most basic application of low-hydrogen silicone oil and a core raw material for preparing other functional silicone products. Synthesis of Modified Silicone Oils: Modified silicone oils, such as long-chain alkyl, fluorinated, and polyether modified silicone oils, are prepared through the addition reaction of Si-H bonds with compounds containing unsaturated bonds (long-chain olefins, fluorinated olefins, etc.), and are used in cosmetics, coatings, and other fields. Preparation of Silicone Rubber Crosslinking Agents: In addition-cured silicone rubber (HTV, RTV), it reacts with vinyl-containing base rubber compounds to form a three-dimensional network structure. Compared with traditional vulcanization methods, it has advantages such as lower vulcanization temperature, no by-products, and stable performance, and is used in the production of sealing rings, medical silicone, etc.
2. Material Surface Modification and Functional Enhancement
By reacting with the material surface, new functions are imparted or existing properties are enhanced. Resin Coating Modification: Added to coatings such as epoxy resin and polyurethane, it can improve high and low temperature resistance, weather resistance, and corrosion resistance, improve leveling properties, and impart waterproof and stain-resistant functions, suitable for architectural, automotive, and industrial anti-corrosion coatings. Fiber and Fabric Finishing: As a finishing agent, it is fixed to the fiber surface through padding and baking, giving fabrics waterproof, soft, wrinkle-resistant, and abrasion-resistant properties without affecting breathability, suitable for high-end clothing and outdoor waterproof fabrics.
3. A "Protective Shield" for Electronic Products
Provides protection for electronic components, ensuring stable equipment operation. Electronic component encapsulation materials: Acts as a crosslinking agent during the curing of encapsulating silicone resin/potting compound, forming a dense structure that provides insulation, resistance to high and low temperature shocks, and anti-aging protection, suitable for chips, sensors, etc. Electronic potting compound toughening agents: While crosslinking, adjusts the flexibility of the molecular chains, improves the brittleness of the potting compound, enhances impact resistance, and prevents cracking caused by temperature changes or vibrations.
4. Other Applications – All-Round Assistant
"Mold Release Agent: Used alone or in combination for plastics, rubber, and metal die casting. It forms a thin film on the mold surface, providing excellent release without leaving any residue, and can extend mold life. Defoamer: Utilizing its low surface tension properties, it is used in coatings, printing and dyeing, wastewater treatment, and other applications. It provides long-lasting defoaming with minimal impact on system stability. Cosmetic Raw Materials: Modified low-hydrogen silicone oils (such as polyether-modified ones) can be added as emulsifiers and emollients to skincare and personal care products, forming a moisturizing and smooth protective film."
Low-hydrogen silicone oil is like an "all-rounder," serving as a "foundation" for synthesizing other silicon materials, and also directly adding buffs to various products-waterproofing, stabilizing, toughening, it can do everything!
