Poly(oxy(dimethylsilylene)), alpha-(trimethylsilyl)-omega-((trimethylsilyl)oxy)- - Introduction
BAYSILONE OIL M30000, also known as polymethylsiloxane (PDMS), is a silicone polymer. Its chemical structure contains silicon-oxygen bonds and carbon-silicon bonds.
PDMS has the following properties:
1. Low Surface tension: PDMS is a material with very low surface tension, which makes it very useful in coating, lubricant and anti-adhesion applications.
2. Heat resistance: PDMS can maintain chemical stability and physical properties at extremely high or extremely low temperatures, so it is widely used in the field of high-temperature lubrication and thermal conductive materials.
3. Inert: PDMS has excellent chemical resistance to most chemicals and high resistance to acids, alkalis, solvents and oxidants.
4. Transparency: Pure PDMS is transparent and is widely used in optical and optoelectronic devices.
5. Soft and flexible: PDMS has soft elasticity and flexibility, so it can be used to make elastomers, sealing materials and moulds with plastic shapes.
PDMS is widely used:
1. Preparation of flexible electronic and optoelectronic devices, such as sensors and flexible display screens.
2. Medical devices, such as the preparation of artificial heart valves, artificial joints and medical rubber products.
3. Ingredients in cosmetics and skin care products, such as lotions, shampoos and masks.
4. In the biomedical field, PDMS can be used to prepare microfluidic chips and tissue engineering materials.
The preparation method of PDMS is generally synthesized by silanization reaction. The common method is to react dimethyl silanol with chlorosilane or chlorosilane to generate PDMS.
Regarding the safety information of PDMS, it is a relatively safe compound and is widely used in many applications. However, in the use of the process still need to pay attention to the following aspects:
1. When PDMS is decomposed or heated, harmful gases may be generated, so it is necessary to provide good ventilation conditions during operation.
2. Long-term contact may cause skin dryness and irritation. It is recommended to use physical and chemical protective measures during operation, such as wearing gloves, glasses and protective clothing.
3. In the production and handling process, it is necessary to avoid contact and inhalation of PDMS.
To sum up, PDMS is an organosilicon polymer with various characteristics and wide application, which has played an important role in scientific research, medicine, cosmetics and other fields. Pay attention to safety precautions during use to ensure proper use and handling.
