Platinum Liquid Silicone Rubber: Redefining Cake Mold Standards

      In the era of baking that pursues health and aesthetics, platinum liquid silicone rubber (LSR) has become the preferred material for high-end cake molds with its food-grade safety and ultimate process performance.

    Compared with traditional silicone or metal molds, its platinum catalytic curing technology eliminates the migration of harmful substances and has passed FDA international certification.

     Even if it is directly in contact with high-temperature chocolate or acidic mousse, there is no risk, so that every bite of dessert is safe.

1.Why do top bakers choose platinum LSR?

(1) Replicating millimeter-level artistic details

With its ultra-high fluidity, LSR can accurately replicate fondant relief, 3D stereoscopic shapes and even hair-like textures. Whether it is the retro carvings of French desserts or the abstract lines of Internet celebrity cakes, there is no deformation or burrs after demolding, perfectly presenting the designer's original inspiration.

(2) All-round performance from -40°C to 230°C

High temperature zone: uniform heat conduction prevents chiffon cakes from collapsing, and its baking resistance far exceeds that of ordinary silicone;

Freezing zone: mousse is flexible and not brittle when demolding, and the surface of ice cream is like a mirror after molding;

No-bake application: chocolate molding does not require repeated temperature adjustment, and the glossy texture is obtained after demolding.

(3) Efficiency revolution in commercial baking

With a service life of more than 500 times and the characteristics of no mold release agent, it can save 20% of raw material loss. The one-piece multi-cavity mold (such as macaron plate) supports mass production of hundreds of pieces per hour, while maintaining the dimensional error of each batch ≤0.3mm.

General parameters

2.The golden partner of the future of baking
Platinum liquid silicone rubber molds are not only tools, but also "liquid sculptors" for pastry chefs to realize their creativity.

From home kitchens to Michelin kitchens, it reinterprets the possibilities of baking with safety, precision and durability.

3.Main feature :

1. Environmentally friendly, non-toxic, tasteless, non-corrosive, passed FDA food grade, MSDS, ROSH and other certifications.

2. Low viscosity, good fluidity, convenient operation and easy pouring; it can be cured at room temperature or heated.

3. Excellent physiological inertia, waterproof, ozone resistance and aging resistance, high tensile toughness, and many mold turning times.

4. High chemical stability, high and low temperature resistance, can be used for a long time and maintain its performance at -55°C to 220°C.

5. No low molecules are released during the cross-linking process, so the volume remains unchanged, the shrinkage rate is as low as 0.1%, and the precision is high.

4.Mold making process of RTV-2 platinum-cured 1:1 addition-type liquid silicone rubber
(1) Prototype preparation
Clean and process the mold prototype to ensure that the surface is smooth and free of impurities.
(2) Mixing and degassing
Mix components A and B in a 1:1 ratio, stir evenly and vacuum degas to avoid bubbles affecting the quality of the mold.
(3) Pouring and curing
Slowly pour the mixed silicone rubber onto the prototype to ensure that the details are completely covered.
Cure at room temperature or under heating conditions, usually for a few hours to a day.
(4) Demolding and post-processing
After curing, carefully demold and check the integrity and accuracy of the mold.
Surface treatment or secondary curing can be performed as needed.

5.Packing and shipping:
10Kg/set (A component 5Kg +B component 5Kg)
40Kg/set (A component 20Kg +B component 20Kg)
50Kg/set (A component 25Kg +B component 25Kg)

Packed in iron drum or plastic drum, transported as non-dangerous goods, sealed at room temperature 25°C, and protected from acid and alkali impurities, the storage period is 12 months.

6.Precautions :

1. Do a small amount of testing before use, and then put it into use.

2. Do not add color or powder to the silica gel at will before testing. Do not contact with water, acid, alkali or other organic matter containing sulfur, phosphorus and nitrogen, so as not to affect the curing of silica gel.

3. This product is a platinum catalyst silica gel, which cannot be in contact with condensation type silica gel. Before using the silica gel, tools and containers need to be cleaned with thinner water.

         4. If you need to color, please add the color paste to component B by 2/1000, and stir evenly.
