(1) silicone rubber Elongation
Silicone rubber elongation refers to the "limit rupture elongation" or the percentage increase in the original length relative to the original length when the sample breaks.
Hot-sulfur solid-state silicone rubber generally has an elongation in the range of 90 to 1120%.
Fluoro silicone rubber generally has an elongation of between 159 and 699%.
Liquid silicone rubber generally has an elongation of between 220 and 900%.
Different processing methods and the choice of harderner can greatly affect its elongation.
Silicone rubber elongation and temperature have a great relationship.
(2) silicone rubber curing time
Silicone rubber vulcanization time, also named silicone rubber curing time, is said after a long time silicone rubber vulcanization reaction is basically over.
This is basically the end means the product is already available, but in fact there is a small part of the curing reaction is not finished.
So the products made of silicone rubber , such as silicone molds usually need put a period of time and then put into use.
