Why Bother Using Silicone Molds?

The purpose of using silicone is to reproduce your perfect soap bars each time you cast. You want your molds to produce professional soap bars with clean, crisp details of your brand name artwork with the size, shape, and weight of the master soap bar. You have complete control over the exact weight and dimensions of each soap bar.

Our customer appreciation and quality control ratings are excellent.

Unlike plastic sheet molds, silicone molds can be twisted, stretched, pulled, or dropped and they will not lose their shape. Silicone rubber has a memory and this memory allows your molds to return to their original shape.

From the early beginning, Masterline Molds decided to produce a high-quality silicone soap mold for their clients -- a mold which will last for years giving you far greater returns on your purchase. No wonder why soap makers choose silicone molds as their 'anchor go-to-molds' for all their soap recipes.

Do Silicone Molds Absorb Scents or Colors?
Answer: No.

Silicone molds will not absorb scents, oils, or perfume you may use in your own exclusive soap formula. You can cast all your different soap recipes using the same mold. For example, you may use the same silicone mold to make soap bars, wax products, bath Fizzies, hard lotion bars, and even pumice bars. In these cases, your formula would start as a liquid slurry and then solidify to a harden state for de-molding.

Can silicone molds be used for hot or cold recipes?
Answer: Yes.

Silicone molds can withstand temperatures up to 350° F. and for rapid cooling, you can place your molds in cooling units. You can also place them in a freezer for a brief period of time – but, please, be careful.

Masterline use a medium strength, two components, tin catalyzed, room temperature cured with a 20-shore strength silicone.

There is no need to use platinum base silicones as we are not making resin products.

Masterline does not use polyurethane RTV rubber. We found that finished soap bars adhered tenaciously to the polyurethane rubber. No amount of cleaning or use of mold releases could prevent soap bars from sticking to polyurethane rubber which builds a scale-like residue.

The silicone gives a clean release thus eliminating any soap-scale build up.
