Re: Responses-Structural Plastics

Pat Peick CPO

Dear Colleagues,

Here are the various responses to the questions regarding structural plastics

that are translucent or very nearly so.

>>

Pat,

Check out the Otto Bock plastics.

Joe Carideo, CP

Dear Pat,

There are other types of clear plastics on the market, just to name a few,

one from Ipos is called Ipolen, which has different thicknesses. Otto

Bock has Thermolen Stiff, and possibly clear ABS, these few I think

might serve your purpose. Hope this has been some help.

Pat:

Lexan is transparent, very strong and particularly impact resistant.

However, it is also hydroscopic and must be stored at a high enough

temperature that moisture will not permeate the material. When heated to

working temperaturee, improperly stored Lexan will be filled with tiny steam

bubbles and will be unusable.

They (whoever they are!) used to use Lexan for replacement windows when

vandalism was a problem (school windows), but kids learned that extreme

cold, a localized cigarette burn, or (I believe) acid would make the

material brittle. It’s hard to fool kids for long.

Good luck in your search.

Otto Bock makes a clear plastic that they claim can be used as a definitive

socket with proper lamination and reinforcment.

PAT-

There is a material currently utilized in “preforms” for bubble forming molds

which is distributed by PDI (800.459.0177) It is called “Crystal”

It may or may not be too brittle for your needs… I use it for TF sockets “in

the field”….

Good luck
