4. Physiological inertness


Polysiloxane compounds are one of the most inactive compounds known. They are very resistant to biological aging, have no rejection reaction with animal bodies, and have good anticoagulant properties.


5. Low surface tension and low surface energy


The main chain of silicone is very flexible, and this excellent flexibility is due to the basic geometric molecular configuration. Because the intermolecular force is much weaker than that of hydrocarbons, it has lower viscosity, weaker surface tension, smaller surface energy, and stronger film-forming ability than hydrocarbons of the same molecular weight. This low surface tension and low surface energy are the main reasons for its many applications: hydrophobic, defoaming, foam stability, anti-sticking, lubrication, glazing and other excellent properties.
