Description
PIKE Heated Platens Accessory – for Making Thin Films of Polymeric Samples for Transmission FTIR Analysis
The PIKE Heated Platens Accessory is designed to efficiently make thin films of polymer materials for infrared transmission spectroscopy. Thin films are easily made from pellets or other plastic sample forms.
Typically a 2-5 milligram portion of polymer is cut from the pellet or other plastic sample and placed between aluminum disks within the heated base of the platens. The temperature of the platens is chosen to match the melting point of the polymer material. The top plate of the heated platens accessory is placed over the assembly and the unit is placed into the hydraulic press. A low force (2 tons) is generally applied to the sample in the heated platens accessory to make excellent films.
The PIKE Heated Platens Accessory includes insulating disks to maintain the desired temperature set point when making thin polymer films. The insulating disks improve the quality of thinfilms, by making them more IR transmissive and thereby improving the quality of the spectra produced from the pressed films. This is achieved by holding the temperature at the melting point of the polymer during the film making process. Flattening the polymer below its melting point produces a cloudy film. Pressing the polymer film when it is above its melting point may cause polymer degradation.
The PIKE Heated Platens Accessory is compatible with the PIKE CrushIR™ Hydraulic Press and other hydraulic presses (please inquire).
