Slide 1 of 1, currently active

General Info

PROTEUS® LDPE (LOW DENSITY POLYETHYLENE) is more flexible than HDPE. LDPE is easily vacuum or draped formed into prosthetic devices that offer more flexibility of motion. LDPE also provides good chemical resistance and impact strength and is easy to fabricate into industrial parts. Proteus® LDPE meets FDA criteria for use in food processing and packaging.

Key Properties

Light-weight
Good impact resistance
Extremely flexible
Easily cleaned
Thermoforming performance
Meets food handling guidelines
No moisture absorption
Chemical- and corrosion-resistant

Limitations

High Heat Environments
High Loads
Subject to Creep, Cold Flow
Thermal Expansion
Tight Tolerance Applications

Applications

Die Pads
Hinges
Impact pads
Orthotic and Prosthetic devices
Thermoformed parts

Proteus® LDPE

Boedeker Plastics, Inc. stocks & supplies plastic sheet, rod, tube, film and custom profiles and machine parts from these shapes that are produced from plastic resin. In many cases the manufacturer of the shape has their own product trade name. If your specification calls for a specific resin grade or manufacturer trade name, we can supply a shape made from that resin to meet your specification or suggest an equal. If you require a specific resin or brand it must be specified at the time of order.
