1. The Chinese name of PDMS is polydimethylsiloxane, and it is inaccurate to call it methyl silicone oil. Generally, methyl silicone oil refers to PDMS whose end is also methyl. PDMS is a general term for a class of substances, which is characterized by D-Link as dimethylsiloxane link, but the end sealing will be different, such as methyl end sealing, vinyl end sealing and hydrogen end sealing


2. Amino silicone oil, vinyl silicone oil, hydroxyl silicone oil, etc. are not necessarily PDMS, but mainly the position of the functional group. If they are terminal, they can be considered as one of PDMS. If they are on the side chain, they can not be called PDMS


3. Amino silicone oil, vinyl silicone oil and hydroxyl silicone oil are not prepared on the basis of PDMS. Generally, these kinds are directly synthesized with monomers


4. Amino and hydroxyl silicone oils contain hydrophilic groups. Why are they highly hydrophobic materials? The above silicone oil with high molecular weight is not hydrophilic, and the silica chain link is hydrophobic


5. Why does amino silicone oil have good bonding effect when it is applied to the surface of other materials, while other kinds of bonding are general and can be rubbed down by hand? Look at what material it's painted on. There's no answer here
