4" Diameter 316SS Polymer Film Pressing Platens

Product Description

The 4" diameter polished platens are useful for making large diameter polymer films. The platens are made from 1/2" thick 316SS. Platen surfaces are polished to a mirror finish or are available lapped flat to a finely honed matte finish. Matte finish platens are useful for limiting fringing of polymer films which take on the surface characteristics of the platens against which they are pressed. There are ports in the platens to enable insertion of a thermocouple probe. The platens are also tapped with a female thread to allow attachment of an optional handle. Optional spacers to contain polymer samples are available in thicknesses and diameters specified by the customer. The platens are compatible with our standard heated platens (43212-6664).

Superior Polymer Film Release

The platens mirror-polished finish dramatically reduces adhesion between the platen and polymer films, promoting effortless release after pressing. This feature not only speeds up sample preparation in laboratories but also preserves the integrity of delicate polymer films, making the platens an ideal tool for researchers and manufacturers focused on high-precision film quality with minimal wastage.


Durable, High-Temperature Performance

Constructed from premium 316 stainless steel, these platens withstand rigorous operating conditions, enduring up to 400C continuous heat exposure. Their outstanding corrosion resistance assures consistent longevity, even under aggressive laboratory environments or frequent temperature cycling, ensuring reliable and repeatable polymer pressing every time.


Versatile and User-Friendly Integration

With their universal 4-inch diameter and chamfered edge design, the platens are compatible with both manual and hydraulic press systems commonly used in laboratories and manufacturing settings. Simple to install, these platens facilitate various pressing and shaping assignments, making them suitable across research and industrial applications where precision and surface integrity are paramount.
