Materials & Applications
We stay out in front of the competition
Airlite supports orthoform® in our commitment to consistently deliver high-quality products to the orthotics and prosthetics industry.
|Product Type||Description||Typical Applications||Flex. Mod.
(psi per ASTM D790)
|LDPE||Soft, flexible and lightweight||Spinal orthoses requiring some support and comfort, upper extremity orthoses, flexible prosthetic sockets||32,000||275-330|
|HDPE||High durability, high strength, resists cracks||Spinal orthoses and body jackets, areas requiring good flexural fatigue properties||170,000||275-330|
|Modified PE||Softness of LDPE with added rigidity for support||Spinal orthoses requiring moderate to slight rigidity, upper extremity orthoses, prosthetic sockets||52,000||275-330|
|Polypropylene-homopolymer||Good formability. Economical, rigid, high impact resistance||Lower & upper extremity orthoses (AFO, DAFO, cro walkers, etc). Spinal orthoses required added support and stiffness, die cut components requiring good memory or “living hinge” characteristics||190,000||310-325|
|Polypropylene-Copolymer||Very good formability
improved impact properties – good stiffness with a bit of flex
|Lower extremity orthoses requiring a bit of flexibility,spinal braces, upper extremity orthoses||160,000||310-325|
|LLDPE||Formability comparable to LDPE, soft, lightweight||AFO applications requiring flexibility and resilience, flexible prosthetic sockets||40,000||275-330|
|TPE||Ethylene propylene thermoplastic, semi- rigid, flexibility, durability||Lower extremity orthotics||property varies with grade||390-410|
