Silicone
rubber for food product mold making
1: 1 component liquid silicone is addition type 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 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.

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.
