function Forte’s shape retention function

Forte is a plastic sheet material created with SEKISUI SEIKEI’s unique molecular orientation technology that enables it to retain its shape after bending, similar to metal or wire. Forte contributes to product development with features absent in metal, like light weight and excellent processability.

Light weight

Forte has a specific gravity of 0.97 and is so light it floats on water. Switching from other materials can reduce the weight of products.

	Forte	General-purpose polyolefin	Aluminum
Thickness	0.6mm	0.5mm	0.5mm
Specific gravity	0.97	0.95	2.7
Tensile strength	500MPa	24MPa	270MPa
Young’s modulus	14GPa	1GPa	70GPa

Nonmetal

Forte is made of polyolefin and can safely be used with a metal allergy.
It does not rust or break from metal fatigue like metal does. It does not affect magnetic fields and does not trigger metal detectors.

Recyclable

The main material in Forte is polyolefin that is made of carbon and hydrogen. It does not contain any metal or glass and is easy to recycle.

Processability

Forte can be adapted into various sizes in post-processing such as sheet punching or slitting.
Narrow slitting can create an alternative for wire.

Slitting
Punching (single layer sheet)
Punching (laminated sheet)
Punching and adhesive processing
Half-cut adhesive processing

type Types of Forte sheets

Forte (single layer sheet)

The molecular orientation in Forte is in the machine direction, and it retains its shape when bent in the machine direction.
It does not retain its shape in the transverse direction and will eventually snap.

Forte (laminated sheet)

This is a laminated sheet of Forte with alternating orientation direction.
Lamination allows it to keep its shape when bent either vertically or horizontally.
