Rolyan Polyflex II Thermoplastic Splinting Material

Polyflex II™, the second iteration of Polyflex, is a polycaprolactone-based splinting material that offers a balanced combination of high conformability and low resistance to stretch. It provides outstanding natural drape — just less than Polyform — and ease of moulding. This makes it an excellent choice for splints that require a precise fit. Although it has a low resistance to stretch, Polyflex II still has excellent strength, rigidity and flexibility when cooled.

Polyflex II has a water-based, non-stick coating, which prevents accidental bonding. It can be reheated and reshaped repeatedly, but once it has been stretched, it will not return to its original shape. Polyflex is non-toxic, latex-free and radiolucent. It’s recommended for finger and hand splints, dynamic splints, neck collars, and more.

Polyflex II is the only Rolyan splint that is flexible enough when cooled to directly resist stress fatigue. It will resist the start and spread of cracks caused by high load flexing of the splint, making it the ideal choice for splints used in a heavy work environment.

Resistance to stretch: Minimum

Stretches easily when heated and only requires soft, gentle pressure to form a splint, allowing clinicians to have excellent control. Be careful not to allow material to stretch too much.

Conformability: Maximum

Easily conforms to surface contours and detail, reducing time to fabricate splint, and provides a precise fit for increased comfort and fewer pressure areas. High degree of drape.

Memory: Minimum

Ability to be reheated and reshaped but will not return to original shape.

Bonding: Coated

Create a temporary bond by pinching together heated material; however, it will come apart when cooled. Form a permanent bond by scrubbing off the coating or removing it with a bond solvent.

Colours: Assorted
White, beige or blue

Thickness: Assorted
Available in the following sheet thicknesses: 1/8" (3.2mm), 1/16" (1.6mm) and 3/32" (2.4mm). Suitable for larger fracture braces or intricate paediatric splints.

Perforations: Assorted
Available in 1 percent or solid material.

Appearance: Opaque when heated

Rigidity: Moderate (49.8 kpsi*)
Retains shape without reinforcement.

*Refers to Young’s Modulus testing value

Surface: Smooth
Picks up fingerprints and markings if not properly handled.

The recommended method for heating splinting materials is with hot water in a splint bath. A heat gun should only be used for spot-heating and adjustments.

Note: Overheating splinting materials increases the draping/stretching characteristics; allow material to cool slightly before handling to avoid excess stretching.

Splinting materials are intended to be used for fabrication of custom moulded rigid splints, orthoses, and adaptive equipment.
