Silicone rubber
According to the vulcanization mechanism, silicone rubber can be divided into high temperature vulcanized silicone rubber (HTV); vulcanized silicone rubber (RTV) and addition-molded liquid silicone rubber (LSR), which have heat resistance, cold resistance, ozone resistance, ultraviolet resistance, and atomic oxygen resistance. Resistance to cosmic rays and comprehensive performance such as waterproof and shockproof.
Silicone rubber has the characteristics of physiological inertness, non-coagulation, disinfection and substitution. It can be used to make silicone rubber parts that can be implanted into the human body and various reusable silicone rubber catheters, intubation tubes, hydrocephalus drainage tubes, peritoneal dialysis tubes, and Artificial heart-lung machine blood transfusion pump tube, etc.
In addition, silicone rubber has air permeability and has different permeability to different gases. The oxygen transmission rate is the highest among synthetic polymers and can be used as oxygen-rich membranes and gas separation membranes.
