The differences between Liquid Silicone and Solid Silicone
Silicone rubber can be divided into two types according to the form of existence, liquid silicone rubber and solid silicone rubber.
Because of different forms of existence, they have distinct physical performances, which also results in significant differences in application.
This article will discuss the differences between the liquid silicone rubber and solid silicone rubber.
1.Vulcanized silicone rubber products and mixed silicone rubber are solid.
1)The solid silicone rubber we mention here is mixed silicone rubber, which is also known as high-temperature silicone rubber.
2)This kind of silicone rubber can only be completely vulcanized in high temperature no matter which kinds of vulcanizing agent
is used in order to get the ideal physical performance.
3)Solid silicone rubber can be made into all kinds of silicone products after vulcanization, which generally have good physical properties.
4) Solid silicone rubber can reach food grade standard by FDA approval after two-times vulcanization process.
5)Thus, solid silicone rubber can be applied in both industry and foodstuff.
2.LSR has more variety, and it is liquid because it is made of original organic silicone material.
1)Owing to the sulfur of movement, LSR is easier to form, so it can be easily made into mould used to copy product, which is what
solid silicone rubber unable to meet.
2)Moreover, it can also be made into adhesive being adhered to a variety of materials.
3)The majority of LSR can be vulcanized at room temperature.
4)LSR can be divided into condensed type and addition type according to the reaction types.
The fomer generally can not reach the food grade standard while the latter can do.
Therefore, addition type LSR is used in all walks of life because of its very good physical properties.
