food grade silicone rubber for chocolate molds

Application of food grade Silicone Rubber for food grade :

food grade silicone rubber for chocolate mold is mainly used for food mold , such as chocolate mold , cake mold , bread mold , candy , and it is also suitable for concrete product , cement product and so on.

Operation Instruction of High Transparent food grade silicone rubber for chocolate mold :

food grade silicone rubber is a flowable liquid, and the quality has nothing to do with the color. It consists of two component. , after your previous work of dealing with the original model, take some liquid silicone rubber , and mix them evenly with mix of 1:1. Then after vacuum-pumping the mixture, you can pour it into the mold frame. The silicone mold will cured in 2-3 hours.

Note: The time for vacuum-pumping should be less than 3—5 mins ,otherwise, once the silicone rubber has cross-link reaction during vacuumizing, it will not be operated.

FAQs of the food grade silicone rubber for mold making

What should you do for deformation of the silicone mold ?

It should deal apart according to the size of the products, In principle, the hardness of the silicone should be according to the size of the products. If the products features small size and detailed patterns on it, the soft silicone can be applicable which the shore A should be 15-20 for easy demoulding and not damage of the patterns. Other wise harder silicone should be needed for large size products, such as products with size 50cm will need harder silicone with 40-50 shore A , then no-deformation. If Large products but features detailed patterns then 30 shore A silicone will be workable.(The process should be a layer silicone add a layer fiber glass or cloth..).The outer of mold can be plaster, glass fiber reinforced plastic(unsaturated resin and fiber glass) to protect the products from deformation.

How to deal with the bubbles during the mixing process?

It depends on your practical situation. Firstly you can deal the mixture with a vacuumizer if you have one; If no such machine, you can reduce the mixing ratio of the hardener from 4% to 1%-2%.Then in the prior period of the reaction of the mixture will be slower, then the air in the mixture will exhaust by itself for a longer curing time to release the bubble.
