Forj is a high strength, lightweight plastic ribbon that molecularly fuses to itself in a matter of seconds. Simply heat, press and repeat to form the plastic into any desired shape. Once cooled, the self-bonding plastic hardens, creating a bond as strong as steel.

How it Works

1. HEAT: Heat ribbon to 140°F or hotter to bend and mold Forj into desired shape. You can use hot water, a hair dryer, a heat gun, a microwave, open-flame or solar magnification.

2. SHAPE: Once Forj becomes clear, the resin is hot enough to be shaped and adhere to itself to form a bond. As it cools and solidifies, it returns to white.

3. FIX: Let your creation set for a few minutes. Once cooled, the lightweight material molecularly fuses to itself for a bond as strong as steel.

Reheat & Repeat

If adjustments or additions are desired, simply reheat Forj. Forj can be reheated and reformed several times.

Strong as Steel

We mean that literally. A single ribbon of Forj boasts a tensile strength of over 1,000 lbs


Forj is made from incredibly durable, lightweight materials, giving it a wide range of flexibility. 100 ft. of Forj weighs less than 1 pound.


Forj is available in a convenient tin, making it easy to carry. Throw Forj in your backpack before an adventure or store in a toolbox for future use.

Moisture Resistant

Forj’s base materials do not pick up any moisture and will remain waterproof.

Malleable & Adaptable

Forj’s molecules decouple, allowing you to mold, shape, and form into any desired shape. When cooling, the molecules recouple to create a high strength bond at the molecular level!


The chemical composition of Forj creates a surface that can be painted to match any desired color.

Excellent in Cold Weather

Due to the nature of Forj’s polymers, the bond between molecules and layers gets stronger as the temperature drops.
