Does the solid content of liquid silicone affect its performance?
The solid content of liquid silicone has a significant impact on its performance, mainly reflected in the following aspects:
1. Viscosity
High solid content: higher viscosity, poor fluidity, suitable for applications requiring higher mechanical strength.
Low solid content: lower viscosity, better fluidity, suitable for applications requiring fine processing or complex shapes.
2. Curing time
High solid content: shorter curing time because more solid components participate in the reaction.
Low solid content: longer curing time because there are fewer solid components and the reaction speed is slower.
3. Mechanical properties
High solid content: higher mechanical strength, hardness and wear resistance after curing.
Low solid content: lower mechanical strength after curing, but better flexibility and elasticity.
4. Shrinkage rate
High solid content: larger shrinkage rate during curing, which may cause dimensional accuracy problems.
Low solid content: smaller shrinkage rate and better dimensional stability.
5. Chemical resistance
High solid content: generally has better chemical resistance and is suitable for harsh environments.
Low solid content: poor chemical resistance, suitable for mild environments.
6. Transparency
High solid content: low transparency, may appear turbid or opaque.
Low solid content: high transparency, suitable for applications requiring high transparency.
7. Processing performance
High solid content: difficult to process, requires higher process requirements.
Low solid content: good processing performance, suitable for complex shapes and fine processing.
8. Cost
High solid content: higher cost because of more solid content.
Low solid content: lower cost because of less solid content.
