Rubber Molds For Candle Making

Rubber molds for making candles have many advantages. I will explain the benefits and disadvantages of various types of rubber molds.

For preliminary information, there are three materials made from rubber molds; Latex, Polyurethane and silicone. Latex is an original rubber mold but with advancements in the polymer industry, latex molds are rapidly becoming extinct.

Polyurethane Mold: This mold is flexible but does not stretch well. Polyurethane prints when stretched do not always retain their original shape. Because they don’t stretch too, some polyurethane molds come with a split on the sides which allows them to be dimolded more easily. This does not leave a real parting line. They are usually cheaper than silicone rubber molds. They do need a release agent and sometimes have a strong scent that can rub off on your wax. Many large pillars and taper candles are made from polyurethane. When your candle hobby turns into a thriving business, polyurethane molding is a sure choice for mass making unique shaped candles.

Storing and cleaning polyurethane molds: Polyurethane molds should not be stacked or stored in a distorted position. If kept in a distorted position they will remain like this and can become unusable. Warm water and soap will be enough to clean this fungus. Make sure the water has dried or evaporated before using the mold again.

Water and wax do not mix.

Silicone mold: Silicone mold is the most expensive. They have superior quality when compared to their peers. They don’t need a release agent. They come in various sizes, shapes and flexibility. They will stretch to some extent and maintain their original shape. They are usually intact and do not reveal parting lines.

Storing and cleaning silicone molds: Silicone molds should not be stacked or stored in a distorted position. If kept in a distorted position they will remain like this and can become unusable.

Warm water and soap will be enough to clean this fungus. Make sure the water has dried or evaporated before using the mold again. Water and wax do not mix.
