Product Details

aortha® Thermoplastics

aortha® plastics are designed for use in Orthotic and Prosthetic appliance manufacture. aortha® Thermoplastic materials comes in both sheet and CAD-CAM formats. The latter can come in the form of either cut blocks ready for the milling machine or heat mouldable orthotic blanks.

If used correctly, aortha® Thermoplastic materials will produce a finished O&P device that is comfortable, functionally enduring and pleasing to the eye.


aortha® PPC

Copolymer Polypropylene plastic has excellent physical characteristics, particularly for applications where impact strength and heat resistance is important. The ability of Polypropylene to yield pressure and torque, yet consistently return to its form without fatiguing, will eliminate distortion.

Copolymer Polypropylene (contains up to 15% Polyethylene) produces solid Orthoses. Very popular as it is economically priced, this material is used for practically all Orthotic applications.

Typical thermoforming temperatures:

180-200°C.

General features:

● Lightweight
● Good rigidity
● Good impact resistance
● Various colour options

Applications:

AFOs, KAFOs, RGOs, AK Sockets, Body Jackets


aortha® PPH

It is made of pure Polypropylene (Homopolymer) that gives a higher rigidity in thin applications. Polypropylene offers a high strength-to-weight ratio making it stiffer and stronger than Copolymer Polypropylene, and is excellent for use in thermoforming. aortha® PPH can be used to create thinner applications than the aortha® PPC however it is more brittle when stressed.

Typical thermoforming temperatures:

180-200°C.

General features:

● Lightweight
● Good rigidity
● High clarity
● Good impact resistance
● Tough and flexible

Applications:

KAFOs, AFOs, AK Sockets, Body Jackets


aortha® Dynamic

These are sheets made of transparent thermoplastic Copolyester. Offering high impact strength, Dynamic can be rapidly thermoformed at low energy consumption and can withstand extreme degrees of stretching. Owing to the excellent flow and mould surface reproduction, Dynamic sheeting can be thermoformed at low temperatures requiring little energy for producing applications.

Typical thermoforming temperatures:

60-80°C.

General features:

● Excellent thermoformability
● Good impact strength
● High breakage resistance
● Easy to fabricate, form and bond

Applications:

Prostheses, Specialist Equipment


aortha® ABS

ABS (Acrylonitrile Butadiene Styrene) sheeting is a general purpose material that suits most applications where robustness is paramount. It has very good toughness with a high degree of rigidity, and heat resistance. It is suited for both vacuum and press forming. During thermoforming the use of a heated steel or aluminium mould is strongly advised. aortha® ABS material is easy to thermoform and has a broad visco-elastic range that gives good melt strength over a large temperature.

Typical thermoforming temperatures:

150-185°C.

General features:

● Very good impact strength compared to most polymer types
● High rigidity
● Lightweight
● Versatile

Applications:

Heel Caps, Orthopaedic Helmets


aortha® Flex

This is a transparent material made from an aortha® EVA and aortha® LDPE mix (76% LDPE 24% EVA). Due to the EVA content the material is very flexible. aortha Flex® has excellent tear resistance and and be stitched or riveted.

Typical thermoforming temperatures:

150°C.

General features:

● Transparent
● Very flexible
● No shrinkage
● Good work-ability and flexibility

Applications:

Body Jackets, Wrist splints, Spinal Orthoses, Neck Braces, AFOs, AK/BK Liner Sockets


aortha® PE500 & PE1000

These are lightweight high density polyethylenes with little to no memory. It is usually coupled with reinforcement to keep it’s moulded contour.
The thickness required is selected by patient’s weight or prescription instructions. The aortha® PE500 provides tough rigid results with the aortha® PE1000 being very rigid when applied providing a much firmer finish making the material ideal for larger/ heavier patients. Our high molecular weight material is press moulded and provides very good impact and flexible strength.

Typical thermoforming temperatures:

160-185°C.

General features:

● Press moulded
● Very good impact strength
● Good flexural strength
● Produces strong, rigid orthoses

Applications:

AFOs, KAFOs, FFOs, Body Jackets


aortha® LDPE

This is a versatile low density polyethylene that can be sawn, cut, die cut or pinched. The main characteristic is it’s flexibility therefore making it ideal for applications where movement has to be considered. It can be shaped by drape, frame injection, vacuum and pressure moulding techniques.

Typical thermoforming temperatures:

130-150°C.

General features:

● Flexibility
● Good impact strength
● Very low shrinkage
● Soft to the touch
● Exceptional stress crack resistance properties

Applications:

Body Jackets, Wrist splints, Spinal Orthoses, Neck Braces, AFOs, AK/BK Liner Sockets


aortha® Drape

An advanced range of thermoplastic materials for the production of check sockets and flexible sockets. Carefully selected raw materials and advanced extrusion technology result in sheet materials with superb aesthetic qualities and outstanding handling and performance characteristics.

The materials pull easily, uniformly and the side walls will not thin out and tear. Tearing and deforming issues are a thing of the past.
Issues resulting from cold flow, excessive friction, discolouration and more will be eliminated or minimised. aortha® Drape materials will enable you to achieve the improved patient outcomes while helping you increase productivity.

General features:

● EVA Based
● Semi-transparent
● Very flexible
● Excellent transparency
● Superb forming properties

Activation temperature:

150°C

Applications:

Transparent rigid check sockets, Highly flexible prosthetic devices.
