Copyflex Liquid Silicone Mold Making Rubber


CopyFlex® is a food grade, liquid silicone rubber that was designed specifically for mold making. Unlike many liquid silicones that have complicated mix ratios and very thick consistencies, CopyFlex® is easy to use because equal amounts of both catalyst and base are combined to produce a silky smooth, low viscosity liquid silicone rubber that reproduces the finest details. A 1:1 mix ratio is very convenient for large projects and also enables moldmakers to easily pour molds that may weigh as little as two ounces. Conventional liquid silicone mold making rubber often has a cure time of 24 to 36 hours which is very long when compared to CopyFlex® which will cure in four hours at 70 degrees F.

When you order CopyFlex®, you will receive one half of the amount you ordered as Part A and the other half as Part B which combined will create CopyFlex®.

Buy More & Save!

CopyFlex® is sold by the pound. As your order increases, the total cost decreases. In other words, if you purchase anywhere from 1 to 4 pounds, your cost per pound is $25.00. If you purchase anywhere from 5 to 9 pounds, your cost per pound is reduced to $24.00, and so on.

Most Common Mold Types

Blanket Mold

This is by far the easiest type of mold. It is often use to reproduce plaques and models in which one side is not covered by mold material. In this process, the original is fixed to a base usually with hot glue and the molding material is poured over it and allowed to cure. When set, the mold is flipped over and the original removed to reveal the blanket mold ready for casting material.

Block Mold

In this process, the original is fastened inside a mold box or container. The mold material is introduced and filled to about one inch higher than the highest part of the original. When the mold is removed from the box or its container it resembles a block of mold material, thus its name. To remove the original a slice is made on each side of the rubber the going two-thirds down. The mold is spread open like a clam shell and the original is removed. A rubber band is used to keep the mold closed when the casting material is poured.

Two-Part or Complex Mold

For a complicated original, a more complicated mold must be constructed. First one side is molded, followed by the other side. Or if even more complicated addition mold pieces need to be made.

Injection Mold

Release Agent

Most mold materials require a release agent to prevent item from sticking the original. Silicone often does need a release. Carefully read the instructions on each mold making material so you are aware of what type of release agent you may need.

There are number of types of molds to name a few: blow, injection, matrix, extrusion, rotational, spin and transfer. The majority of which require specialized equipment to complete the process. Here we will be concerned with the types of mold constructions which can be created by you. These include blanket molds, box molds, two-part or complex molds and injection molds.

Finally, an explanation is in order for the types of mold making materials by which molds are constructed. Most mold making materials are utilized are made from natural or manmade rubber because of their flexibility and the ability to reproduce extraordinary detail. But some molds are made with more rigid materials such as gypsum plasters. The most common mold rubbers are natural latex, polyurethane, epoxy and silicone. These groups also breakdown into category types. For example, there are two types of natural latex, one used for mold making while other is used for casting. Silicone has two distinct families, a condensation cure and an addition cure. One is best suited for a certain project over the other. So you need to become familiar with which materials will provide the best results.

Copyflex Weights And Measures


  • 1 pound of CopyFlex® will cover an area about 9 1/2 x 9 1/2 x 1/4 thick.


  • 1 pound of CopyFlex® = 12 1/2 fluid oz. = 1 1/2 cups = 3/4 pint
  • 1 pound of CopyFlex® = 370 millileters = .37 liters
  • 1 pound of CopyFlex® = 22.85 cubic inches

How to Calculate Quantity Needed:

In inches, take the L x W x Thickness of the area you will be covering with the CopyFlex®. This will give you the total cubic inches of the CopyFlex® layer that you are going to use to make your mold. Then multiply total cubic inches by .70 to find the weight in ounces of CopyFlex® you will need. Divide this number by 16 to calculate pounds of CopyFlex® required.

Example: Lets say you need to cover an area that is 9 inches wide and you want to apply a layer of CopyFlex® that is 1/4 thick.

The calculation is as follows: 9 x 9 x 1/4 = 20.25 cubic inches x .70 = 14 ounces in weight.
