Food grade silicone rubber for chocolate molds with 15-30 shore A

Description 

Food grade silicone rubber for chocolate molds are generally named as two-part addition silicone rubber that vulcanises at room temperature.Part A is a flowable liquid, part B is the curing agent(platinum catalyst). It features an exceptional fluidity ,good operability,excellent physical properties and very low shrinkage. The mixing ratio between Part A and Part B can be 10:1 or 1:1.

Features

Good fluidity and good operability and good for pouring method.
Excellent mechanical properties, in particular tear strength and tensile strength.
Excellent flexibility and it is easy to demould.
High temperature resistance, high duplication times and repeated use.
There are a range of catalysts/curing agent/hardener allows the Liquid rtv silicone rubber  to fulfill requirements for various applications and various requirements on the operation time and curing time.

Operation ways 

1.The cast pouring, for example:
Prepare a frame, fix the prototype for copy into the frame, (if the prototype’s material is glass or ceramic, the release agent is necessary to prevent sticking.
2. Take 1 part A and 1 part B,mix themevenly.
3.Vacuum defoaming in 1~3 min,inject the rubber into the type box, then vacuum defoaming again, curing 24 hours in nature room temperature, use it after demold.
4. Demold after 3 hours’ room temperature curing, and then use it after 24 hours’ keep mold under the same condition.

Operation way 

If the customer wants to make large products and large size moulds, the mould should be made of silicone rubber with high hardness. On the contrary, if the mould with fine and precision  patterns, it should be made of silicone with low hardness. The amount of the curing agent depends on the actual requirements of the customer. If moulds requiring fast drying and demould, more curing agent is needed; contrarily, if moulds requiring slower drying and demould, less curing agent is needed.Our curing agent is free charged.
(Note: our company does not recommend you to add silicone oil. If a special soft silicone mold or fine detailed and complex patterns products are required, 5%-10% silicone oil can be added to soften the mold for easy demould.)
