Why silicone rubber add curing agent after mixing a lot of bubbles?
--This is normal physical phenomena. The liquid will produce a large number of bubbles in the mixing time, so, it must pass through the vacuum exhaust bubble treatment.
Working temperature of liquid mold silicone
The working temperature of liquid mold silicone is between -40℃ and 250℃
The molding temperature of liquid silicone products is determined based on the properties of the product. Room temperature vulcanized silicone rubber can be divided into condensation type and addition type according to its vulcanization mechanism; it can be divided into two types according to its packaging method: two-component and single-component. The nature of the silicon-oxygen bonds that make up the main chain of silicone rubber determines that silicone rubber has advantages that natural rubber and other rubbers do not have. It has the widest operating temperature range (-40°C to 350°C) and has excellent high and low temperature resistance.
Features
Liquid mold silicone has a shelf life of 12 months.
Liquid mold silica gel is a two-component liquid silica gel. It is generally stored in a ventilated, cool, dry place, sealed and stored away from children and away from direct sunlight. During transportation, glue A and glue B cannot be mixed evenly before being stored. This will cause all the silicone gel to solidify and lead to scrapping.
