Rheological characterization of various percent weight of silicon rubber

Silicone rubbers are widely used for many industries purpose. There are two type of silicone rubbers which are liquid silicone rubbers and solid silicone rubber. However, liquid silicone rubber is uncured state or adhesive state which is required catalyst to be cured to form solid state. However the curing process is the result of the crosslink and curing agent. However, the right amount of percent weight between the liquid silicone rubber and curing is the key to determine the effectiveness of curing process take place. This report is to study the rheological properties and crosslink behavior on various percent weight of silicone rubber. The method that used in this experiment is mix and pour technique and the equipment involve is Electronic Rheometer. There are 5 sample of different ratio percent weight part A (liquid silicone rubber) and part B (platinum catalyst) which are 1:10, 2.5:7.5, 5:5, 7.5:2.5 and 10:1 As the end of the experiment, percent weight 10:1 give a better potential in term of curing process as it is highly crosslink, crosslink achieve and the sample shown a elastic behavior.
