Method for making polymer particulates, such as spherical powder and whiskers, by melting a polymer material under conditions to avoid thermal degradation of the polymer material, atomizing the melt using gas jet means in a manner to form atomized droplets, and cooling the droplets to form polymer particulates, which are collected for further processing.
Polymer powders that are too large or inconsistent in size and particle structure can deliver products that are less durable, weak and less aesthetically appealing. Methods for Polymer Grinding. Depending upon the application in which the powder will be used, a variety of polymer grinding …
SLS polymer powders also can be obtained by cryogenic grinding (c.f. PA1101 (EOS)), however, there can be issues with inferior flowability due to edged particle shapes being typical for comminution products [10] and, in consequence, inferior processability [11].
Grinding / pulverising. Smile Plastics pulverises all polymers and plastic granulates to any desired size, from coarse powders to a microfine powder. We use two different grinding methods: Cyrogenic grinding (using liquid nitrogen) Ambient grinding (conventional grinding system)
Ultra-fine Particle Grinding. OGL's cryo grinding process produces much more finely ground particles than conventional milling methods. OGL cryo mills are able to grind many materials to 10µm average particle size or smaller. This improves the particle flow of polymers and dispersion potential for processed polymers and foodstuffs in liquid.

In order to produce fine polymer powders, a special and unconventional cryogenic grinding system was established using liquid nitrogen, where a jet‐vortex mill was used as the grinding mill. The major feature of this grinding process is that heat generation during the grinding period was eliminated.
A major step in the polymer development procedure occurs when the individual resin pellets are ground to a fine powder. For that reason, the choice of polymer grinding techniques becomes a vital component of the overall process. At General Polymer Services, we offer a wide array of grinding equipment, as well as professional advice on which ...
The key is to do the grinding below the glass temperature of the polymer to convert it into a powder - as you mention, if material heats on grinding it can make it more difficult - particularly if ...
