Why choose RUI-HE?


Q: What environment is silicone rubber NOT suitable for?


A: Conventional silicone rubber is not suitable in environments where it comes into contact with oils fuels and solvents. RUI-HE silicone however, performs excellently under such conditions. Silicone rubbers in general also have poor resistance to steam and super heated water.



Q: Is silicone rubber suitable for long- term medical implantation?


A: Silicone rubber has been used for long-term medical implantation. An example is finger joints. The recent bad publicity about breast implants has meant that the major silicone manufacturers do not recommend their products be used for more than 28 days.
