Key Material Benefits

Polyform is the only Rolyan splint material with minimum resistance to stretch and maximum rigidity when cool. This unique characteristic allows the clinician to form a detailed splint with the confidence that the intricate molding will not deform when used.


Resistance to stretch: Minimum

Stretches easily when heated and needs soft, gentle pressure to form a splint. Be careful not to allow material to stretch too much.

Conformability: Maximum

Easily conforms to surface contours and detail, reducing time spent fabricating 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.


Colors: Assorted

White, beige or blue

Thickness: Assorted

Available in the following sheet thicknesses: 1/8" (3.2 mm) and 1/16" (1.6 mm). Use thinner material to combine lightweight comfort with a high degree of rigidity.

Perforations : Assorted

Available in 1 percent or solid material.

Appearance: Opaque when heated

Hardened Splint

Rigidity: Moderate/Maximum (137.7 kpsi*)

Strongest Rolyan splint material when formed and cooled, resisting deformities such as dents, cracks and breaks during use.

Surface: Smooth

Picks up fingerprints and markings if not properly handled.

Rolyan Polyform™ Thermoplastic Splinting Material


Polyform™ was the first material developed by Rolyan and remains one of the most unique low-temperature thermoplastic materials. With a high degree of conformability and low resistance to stretch, Polyform has exceptional rigidity and high impact strength. As the strongest and most conformable Rolyan splinting material, Polyform drapes naturally, leaving the clinician's hands free to mold the intricate contours of the splint gently, while gravity assists in splint positioning. Polyform's stretching properties often eliminate the need for precise patternmaking. It can be reheated and reshaped repeatedly, but once it has been stretched, it will not return to its original shape.

Rolyan Spectrum of Splinting Material

Rolyan provides therapists and clinicians the largest spectrum of hand therapy products and care. Rolyan empowers every therapist with the passion to mold and shape their patients’ recovery.

Heating Instructions

The recommended method for heating splinting materials is with hot water in a splint bath.
Only use a heat gun 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-molded rigid splints, orthoses, and adaptive equipment.

Best uses include:

  • Thumb splints
  • Small finger splints
  • Hand splints
  • Wrist splints
  • Elbow splints for flexion
  • Dynamic splints
  • Neck Collars
  • Foot drop splints
  • Clamshell splints
  • Carpal tunnel splints
  • Pediatric splints
  • Adaptive equipment
  • Splints for arthritis
  • Flexor tendon repair splints

Care & Cleaning

Store at temperatures between 40° and 90°F (4° and 32°C) and less than 65 percent relative humidity. Avoid prolonged exposure to light, especially ultraviolet. Avoid exposure to corrosive and ethylene oxide fumes.

Formed splints will lose their shape in temperatures over 135°F(57°C) and should be kept away from sources of heat such as ovens, hot water, and car windows.

Clean splint with soap and lukewarm water. Allow splint and straps to dry thoroughly before reapplication.

Precautions for finished orthoses
Splint adjustments are to be made only by a health care professional, who is responsible for providing wearing instructions and precautions to other practitioners, care providers and the patient. If unusual swelling, skin discoloration or discomfort occurs, discontinue use and consult a health care professional.
