Food grade silicone rubber for mold making
1: 1 component liquid silicone is addition type non-toxic
and tasteless liquid mold silicone rubber, can be placed in the oven pan,
resistant to high temperature 250 ℃, long-term stability
can be used within 200 ℃. This product pass
the FDA food-grade certification, could be used to produce adult products,
human organs, body parts, mannequin, chest pads, shoulder pads and other soft
silicone rubber. Also used in food molds, candy molds, cake molds, as well as a
good material for soap cake mold making.

Products Procedure
1. Mixing: The A and B rubber 1: 1 weight ratio mix and
stir evenly.
2. Discharge bulbs: For high requirements should be
evacuated discharge bubbles, otherwise the mold will have bubbles.
3. Material pouring: pour the mixing the stirred liquid
silicone into the mold box.
Precautions For Use
1. Before large-scale use, please do small amount of
trial, familiar with the production skills to avoid errors.
2. Do according to the manufacturer's instructions ratio
for quantity, and the weighing accuracy, please remember that the ratio is by
weight rather than volume. After the mixing of AB silicone rubber, stir it
fully to avoid not cure or incomplete cure.
3. When make the mold frame, if 502 glue is applied, pour
the mixing silicone rubber after half an hour or put it into oven at 50℃ for 10 minutes, to
prevent 502 glue and silicone poisoning to make it not cure.
4. To accelerate the curing time, heating method can be
used to speed up the curing rate of silicone rubber.
5. When mixing the AB silicone, mixing in the same
direction. When pour glue, take a little bit of the higher and same position on
the female die on the same position, let the glue flow flat on the master die,
it will increase the flow time of the glue to reduce the bubble.
Generally, the silicone in hardness higher than 20, it will need to do vacuum
pumping before use.
6. 1:1 Addition products will have toxic reaction with
tin, phosphorus, ammonium, chlorine, carboxylic acids, thiol, hydroxyl and
other compounds. It is forbidden to contact with such compounds to avoid the
occurrence of non-curing.
