29-09-2020· One principal strategy for the design of mechanochromic polymers is based on the introduction of mechanoresponsive units, the so‐called mechanophores or mechanochromophores, into polymer chains. For example, Sottos and co‐workers have reported sophisticated mechanochromic polymers by incorporation of spiropyran mechanophores at the midpoint of polymer chains.
Drying of Polymer (including Dehumidifying Dryers, Rotary Wheel Dryers, Low Pressure Dryers, Vacuum Dryers) Most raw plastic material looks dry. However, everything is not always what it seems. Hygroscopic materials such as Polycarbonate, Nylon and PET to name just three, attract moisture from the surrounding air.

Particle size reduction, or grinding, is a process to produce a polymer powder necessary for a particular industry or technology. This can be accomplished by starting with resin pellets or a powder that is ground to a finer powder. At Ancos, we can achieve a range of desired size distributions to meet specifications, from coarse to fine.
01-09-2012· Polymeric microparticles that may be used in rapid prototyping processes typically are produced by either polymerization processes or cryogenic grinding in impact mills at liquid nitrogen temperature (− 196 °C) or by dry grinding at solid carbon dioxide temperature (− 78 °C).Within this account an alternative approach for the production of polymer particles is presented.
Aluminum oxide grinding wheel is commonly used in making the grinding wheel and will be best suited for grinding the ferrous metals having high tensile strength e.g. hard steel, wrought iron etc. ; Silicon carbide grinding wheel is used to grind the softer, low tensile strength, high density and non-ferrous materials such as brass, aluminum and softer bronze.

polymer foils using high throughput reel-to-reel processing promises further reductions in fabrication costs for mass produced thermoplastic microfluidics (Velten et al. 2008). In addition to replication-based fabrication, thermoplastics are also amenable to direct machining techniques such as
All the polymer samples were powdered by grinding under liquid nitrogen. The white powders were sieved through a 325 mesh screen to a particle size less than 44 microns in diameter. Specimens of these polymer were pyrolyzed in a vacuum for 30 min at temperatures up to 400° C after outgassing at 110° C for approximatcl~T 1 hour
