Excellent Electrical
Good Mechanical Properties
Well-Balanced Physical Properties
Higher Impact Strength vs standard PS

Limitations

Brittleness
Poor Chemical Resistance
Poor Weatherability

Applications

Co-Axial Cable Separators
Containers
Handles
Insulators
Knobs & Buttons
Lighting Diffusers
Packaging Applications
Profiles
Refrigerator Door Linings
Sign Panels

Standoffs
Trays

Resin Trade Names

Manufacturer Trade Names

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.
