Candle mold silicone

Commodity Details

Introduction of candle mold silicone:

Candle mold silicone is a kind of liquid silicone rubber, composed of AB two components, that is, component A is silica gel  component B is curing agent. The product has two types: addition type  condensation type. The addition type mold silicone is environmentally friendly silicone,  the ratio between silicone  curing agent is 1:1; the condensation type is industrial-grade silicone,  the ratio between silicone  curing agent is 100:2  100:2.5. Candle mold silica gel can be cured at room temperature  heated to form.


Features of candle mold silicone:

1. Good fluidity, easy operation, easy demolding,  many times of mold turning;


2. It has the advantages of burning resistance, corrosion resistance, tensile strength,  good tear resistance;


3. It does  emit oil  solves the flame retardant problem of candle wick;


4. Addition molding silica gel is non-toxic, tasteless, safe  environmentally friendly;


5. The color, hardness, viscosity,  operating time of silica gel can be adjusted according to customer requirements.


 

Candle mold silicone operation:

1. Mix the silicone  curing agent according to a specific ratio  stir evenly (1:1 for addition-type silicone; 100:2~2.5 for condensation-type silicone);


2. Put the mixed  evenly mixed mold silicone into a vacuum machine for vacuuming  exhausting bubbles (if there is no vacuuming machine, the curing time of the silicone can be prolonged, so that the bubbles are naturally eliminated, but this kind of bubble removal effect is  Very ideal);


3. Spray (coat) the mold  the mold frame that have been made with release agent,  fix the mold in the middle, slowly pour the bubbled silica gel into the mold frame until the silica gel completely covers the mold, then static Just wait for it to solidify;


4. After the silicone is completely cured, demould,  then process the edge burr,  the silicone mold is completed.


Reminder: After the product is demolded, it is recommended to put it into production after being placed for 24 hours, which will help increase the number of mold turning times  the service life of the silicone mold.

Caution for candle mold silicone operation:

1. In order to prevent changes in the physical properties of silica gel, it is recommended  to add silicone oil;


2. The configured silica gel should be used up within the operating time to avoid waste of raw materials;


3. The silica gel  curing agent must be stirred evenly to prevent the non-curing phenomenon of the silica gel due to uneven mixing;


4. The addition-molded silica gel should  be in contact with any condensation type silica gel to prevent the "poisoning" of the silica gel  causing the silica gel to  cure;


5. Addition-molded silica gel should  be in contact with water, impurities, organotin catalysts  compounds containing nitrogen, phosphorus, sulfur, etc.,  these substances should  be mixed in during use, otherwise silica gel will be "poisoned";


6. Smoking should be prohibited during operation.


 

Silicone candle mold uses:

Candle mold silicone is mainly used to make hand-made candle wax figures, DIY candle molds, Christmas candle molds, holiday candle molds, birthday  wedding candle molds, jelly candle molds, handicraft candle molds, lighting candles  various decoration handicraft molds. The recommended hardness range is 10-20 Shore degrees,  the final hardness value is determined according to customer product requirements  processes.
