Product Application Of
Hydroxyl silicone oil - Hydroxyl-terminated polydimethylsiloxane
Hydroxy silicone oil is widely used in silicone emulsions, textile/paper/leather treatments, silicone rubber structure control agents, and various polysiloxane intermediates.
- Used for preparing block polymers and defoamers.
- Excellent structure control agent for silicone rubber: improves processability, extends shelf life, enhances transparency and mechanical properties.
- Used to produce cationic, anionic, non-ionic hydroxy silicone emulsions; combined with hydrogen-containing silicone oil, serves as high-performance treatment agent for textiles, leather and paper.
- Main base polymer for room-temperature vulcanized (RTV) silicone rubber.
- Provides excellent high/low temperature resistance, oxidation resistance and electrical insulation.
- Low molecular weight hydroxy silicone oil effectively inhibits structuring.
- Reacts with Si–OH groups on silica to make it hydrophobic.
- Improves silica dispersion, prevents structuring, reduces gel formation and compound viscosity.
- Optimizes hardness, permanent set and tensile strength of cured rubber.
- Forms a durable silicone film on fibers at approx. 140℃.
- Provides soft, stiff handle and durable water repellency.
- Heat-set film is alkali-resistant and wash-resistant.
- Hydrophobizes fiber substrates to greatly reduce water absorption and boost oil absorption.
- Increases tensile strength and elongation at break by more than 50%.
- Eliminates cracking during processing and meets performance requirements for radiation-crosslinked heat-shrinkable products.
