Inhoudsopgave
Wat zit er in siliconen?
Siliconen is een verbinding van silicium, koolstof en zuurstof waar onder andere siliconenrubber van gemaakt kan worden. Siliconenrubber is onbreekbaar materiaal. Siliconen is niet hetzelfde als plastic, want plastic is gemaakt van andere chemische stoffen.
Is siliconen een elastomeer?
Siliconenrubber is een elastomeer (rubberachtig materiaal) dat opgebouwd is uit silicone, zelf een polymeer, samen met koolstof, waterstof en zuurstof. Siliconenrubbers worden breed toegepast in de industrie en er bestaan talrijke formuleringen.
Why is silicone rubber so resistant to UV and ozone?
Unlike in other elastomers, the inorganic backbone of silicone makes it highly resistant to fungus and chemicals. In addition, silicone rubber is resistant to ozone and UV attacks because the silicon-oxygen bond is less susceptible to these attacks than the carbon-carbon bond of the backbone in other elastomers.
What is the difference between silicone and organorganic rubber?
Organic rubber has a carbon-to-carbon backbone which can leave it susceptible to ozone, UV, heat and other aging factors that silicone rubber can withstand well. This makes silicone rubber one of the elastomers of choice in many extreme environments.
What are the physical properties of silicone rubber?
Silicone rubbers can withstand temperature ranging from -50°C to 350°C (depends in duration of exposure). Parts made of silicone rubber when exposed to wind, rain and UV rays for long periods result in virtually no change in physical properties. Unlike most organic rubbers, silicone rubber is not affected by ozone as well.
What is the weatherability of silicone?
Silicone rubbers have exceptional weatherability. Ozone created by corona discharge rapidly deteriorates most organic rubbers, but has almost no effect on silicone rubber. In addition, silicone rubber can be exposed to wind, rain and UV rays for long periods with virtually no change in its physical properties.
