However, although silicone elastomers generally have the excellent properties mentioned above, they tend to attract dust because their main components are ruborinool and nonlogisan, which is a dielectric material. The durable polysiloxane easily oozes out from inside the elastic body and covers the dust, making it water repellent, so the dust is not absorbed by rainwater and washed away, resulting in significant staining. It takes advantage of the disadvantages of doing so. In addition, various 4. (1q many body whole -: "fi ; J buy (") and from the eyes closed used as 2, i ~ is also always any + W t
