By the appearance of the products, PVC products are relatively coarse compared to silicone products. The surface of silicone products are smooth and with different shade of color.
Judging from the hand feeling, silicone products are soft, flexible and more elastic, and PVC flexible glue is slightly firm, both of them can be adjusted, but PVC has no toughness.
PVC materials have common material and environmental material, they are known as ATBC and PVC, separately, while silica gel can be certified by ROHS which is very environmental and can even reach food grade.
