Properties
- Physical Form
- Typical Properties
- Properties
- By functionalizing the polydimethylsiloxanes at the ends of the chain defined products with 2 organofunctions are obtained. The functional groups are bonded to the polydimethylsiloxane by chemically inert propylene spacergroups, which are stable to hydrolysis.
- Its terminal functional groups render WACKER IM 11 a valuable reactive silicone intermediate, which is useful for typical reactions with suitable functional groups of appropriate compounds, e.g. esterifications, transesterifications and addition reactions with isocyanates. This results in manifold possibilities for further chemical modification, for the synthesis of block copolymer systems or for the modification of organic polymers with silicone.
- Modification of organic systems with polydimethylsiloxanes results in a change of the properties of the system. Typical properties of the polydimethylsiloxane backbone are, for example:
- Low surface tension
- Good softender effects
- High chemical stability
- Excellent high- and low-temperature stability
- Very good low-temperature flexibility
