Question about item

TFC Silicone Rubber Type 18 Food Grade Translucent Medium Hard Shore 30 1:1 - Size: 500g (2x 250g)

Product Information: TFC Silicone Rubber Type 18 Food Grade, Translucent, Medium Hardness, Shore 30, 1:1 - Size: 500g (2x 250g)

TFC Silicone Rubber Type 18 Food Grade, Translucent, Medium Hardness, Shore 30, 1:1
Contents: 500g (250g A + 250g B)

Addition-curing, 2-component silicone rubber that vulcanizes at room temperature (RTV).

The silicone is supplied in high-quality plastic squeeze bottles with a dosing cap.
This makes dispensing very easy and clean.
Precise dosing is effortless, as you would expect from comparable food packaging, and represents a significant improvement over the usual tin cans or wide-mouth bottles.

Food and Consumer Goods
The raw materials used in TFC Silicone Rubber Type 18 are listed in Recommendation XV. 'Silicone' from the Plastics Commission of the Federal Health Office (BfR) on March 1, 2011. The product can therefore be described as physiologically inert. There are no concerns about the use of TFC Silicone Rubber Type 18 in the manufacture of consumer goods within the meaning of the Food and Consumer Goods Act.

Properties and Applications:

Easy to process
Easy mixing of components 1:1 by weight
Excellent flowability, mixture is easy to pour
Currently cross-links to form a durable, rubber-elastic vulcanizate without heat of reaction
Temporarily temperature-resistant up to 180 degrees Celsius
High tear strength and high flexibility
Extremely accurate reproduction of details
Used for the production of molds for food, consumer goods, and body impressions

TFC Silicone Rubber Type 18 is ideal for producing sophisticated, elastic, and durable molds with pronounced undercuts.

For this purpose, the mold must be preheated (annealed) accordingly during production. This allows for continuous temperature resistance up to approximately 100 degrees Celsius. If you require such a baking mold, please contact us so we can custom-make it for you.

TFC Silicone Rubber Type 18 can be used to produce single- or multi-part molds for replicating original models made of wood, glass, metal, plastic, wax, or ceramic casting materials. You can also cast in the prepared molds with all water-soluble casting materials, such as relief casting compounds such as TFC Xyrarock or TFC Xyraflix, TFC alabaster plaster, modeling and model making plaster, casting clay, cement, concrete, etc. You can also easily cast with soap casting compounds (soap glycerin) for making your own soap or waxes for candle making, as well as with casting resins.

In this case, you should pretreat the mold with a release agent before pouring, as casting resins can cause the mold to become brittle after repeated pouring.

Certain substances prevent or slow the vulcanization of TFC Silicone Rubber Type 18, which can be noticed by sticky or blistered surfaces. These include, among others, condensation-curing silicones, organic rubbers, plasticizers, amines, heavy metal compounds, and sulfur-containing substances. High humidity and water can also cause problems. Under unfavorable conditions, surfaces that have come into contact with the aforementioned substances, as well as certain modeling clays, can also cause vulcanization problems. If in doubt, we recommend conducting preliminary tests on a small scale.
