Silicones FAQ Section
What are the main advantages of using silicones?
Silicones offer exceptional thermal stability across wide temperature ranges, excellent electrical insulation properties, and superior resistance to UV radiation and weathering. Their flexibility and durability make them ideal for applications requiring long-term performance. Unlike organic materials, silicones maintain their properties in extreme conditions without degrading.
Are silicones safe for medical applications?
Medical-grade silicones are biologically inert and have been extensively tested for biocompatibility. They are non-toxic, non-allergenic, and resistant to bacterial growth. Many medical devices including implants, tubing, and wound care products use silicones that meet strict FDA and ISO 10993 standards for medical safety.
How do silicones compare to organic rubbers?
Silicones outperform organic rubbers in extreme temperatures, withstanding both higher and lower ranges. They have better electrical properties, superior UV and ozone resistance, and maintain flexibility longer. While organic rubbers may be cheaper initially, silicones often provide better long-term value due to their extended service life in demanding environments.
