I am looking for a plastic that is preferably in the TPE family, that will bond,chemically, with TPX resin. This is a "two shot" injection molding application. The elastomer must be transparant (or close) and have "self sealing" properties similar to a "septum". Low durometer 30 shore A ?
What type of surface finish works well for PSU release.
High polish ? Vapor Hone ? Would an electroless nickel PTFE coating help ?
The application is an injection molded part with a 12" x .400" core.
Looking for an "elastic" resin that is rigid. This material must be "hard" but compressable. After compression, this material must return to it's original shape. Injection molding grade. EtO sterilizable (3x). Radiopaque. Biocompatable.
Durometer > 80 Shore D.
TPE ?
TPU ?
TPV ?
I am looking for tips on how to increase weld line integrity when molding thin walled, long flow front parts.
Do "weld wells" that are trimed off after molding add significant strength ?
Is it possible to coin polymethelpentene to achieve an optically transparent,flat component that is only 0.010" thick ? If so, what molding parameters would help achieve this "warp free" part ?
