The main materials we used are including silicone rubber, fluorubber, natural rubber, neoprene rubber, EPDM, butyl rubber, polyurethane, polyethylene, EVA, ABS, PP, and PVC.
The vulcanization characteristics of a silicone rubber foam made by technology of removing inert filler used as foaming agent was investigated with curometer.
These can be lifted off by pouring a liquid into them, such as plaster, molten alloys, or silicon rubber, which can later harden and create an impression of the print.
