Silicon Rubber


Advantages of Silicon Rubber
1.    Introduction:
Silicon rubber is usually classed as speciality elastomer due to its unique properties and higher price as compared to other common elastomers. There are two types of silicon elastomers. There are thermosetting rubbers that are vulcanized with heat and Room Temperature Vulcanizing (RTV) rubbers.
2.    Advantages:
·        Silicon rubber is resistant to;
Ø Ozone, oxygen, heat (up to 315oC)
Ø UV light
Ø Moisture and general weathering effects.
·        High degree of flexibility.
·   By replacing minor amount of methyl substituents with phenyl groups, low    temperature flexibility (to low as -100oC) is improved.
·     By replacing minor amount of methyl substituents with vinyl groups, compression set resistance is improved.
·      Compounded products give above properties plus;
Ø Superior resistant to compression set
Ø Excellent biocompatibility
Ø Vibration damping over wide temperature range
Ø Thermal ablative properties.
·    Long service life plus circuit integrity with no toxic gas generation, have secured placed of silicon rubber for appliance wiring.
·       Good chemical stability and flame retardancy.
·       Distinctive interfacial properties;
Ø Water repellency
Ø Releasability.
·        Good gas and vapor permeability.
·        Good transparency and coloring properties
3.    Conclusion:
Silicon rubbers give wide range of properties under extreme conditions of temperature. Liquid silicon rubbers (LSR) are processed through injection molding in industries.
There are developments in the optimization of LSR injection molding machines for ease to use, aren’t you curious now?
