Several main materials and products in the silicone industry
1. Silane Coupling Agent
Silane coupling agent is a kind of low-molecular compound. One end of silicon atom is connected with hydrolyzable chlorine or various alkoxy groups, which can be connected with inorganic substances after hydrolysis; the other end has various functional groups that can interact with organic substances. Such as amino, vinyl, mercapto, etc., so silane coupling agents can bridge organic and inorganic substances. There are nearly one hundred commonly used silane coupling agents.
2. Silicone oil
Silicone oil is a low-molecular polysiloxane containing single or different organic groups, which can be made into various viscosities. Silicone oil has low surface tension and large contact angle with water, making it a high-quality water-repellent material. The application of silicone oil or its modified preparations in cosmetics has grown rapidly in recent years. Silicone oil is not oily or greasy when applied to the skin, it feels smooth and comfortable, and can be made into various skin creams.
3. Silicone rubber
According to the vulcanization mechanism, silicone rubber can be divided into high temperature vulcanized silicone rubber (HTV); room temperature vulcanized silicone rubber (RTV) and addition molded liquid silicone rubber (LSR). It has heat resistance, cold resistance, ozone resistance, ultraviolet resistance, atomic oxygen resistance, and The characteristics of cosmic rays and comprehensive performance such as waterproof and shockproof.
Silicone rubber has the characteristics of physiological inertia, non-coagulation, and easy disinfection. It can be used to make silicone rubber parts that can be implanted into the human body and various silicone rubber catheters, intubation tubes, hydrocephalus drainage tubes, and peritoneal dialysis tubes that can be used for a long time. And artificial heart-lung machine blood transfusion pump tube, etc.
In addition, silicone rubber is breathable and has different permeability to different gases. The oxygen transmission rate is the highest among synthetic polymers and can be used as oxygen-rich membranes and gas separation membranes.
4. Silicone resin
The insulating material made of silicone resin belongs to the H class because of its good heat resistance and insulation performance. The motor made of it is small in size, light in weight, and highly reliable. It will not burn out under short-term overheating and overload.
Silicone resin can be used to formulate high-temperature resistant coatings at 500°C; silicone-modified acrylic resin coatings have good weather resistance, water repellency and anti-fouling, and are advanced exterior wall coatings.
