Vacuum forming or thermoforming is a manufacturing method where a plastic is heated and formed, typically using a mold. Vacuum forming machines vary in size and complexity from low-cost desktop devices to automated industrial machinery. The steps below describe the typical process for industrial vacuum forming.

The hydrolysis of PET begins when PET hydrolases consume the plastic polymer and break it down into simpler monomers, in order to adapt to the environment readily. This condition allows the microorganisms to assimilate the plastic monomers as major carbon sources, which are further metabolized into CO 2, H 2 O, CH 4, and N 2 [ …

They operated for long time spans and hence, the polymer particles were consistently smaller than those we produced during grinding. Molina-Boisseau & Le Bolay (1999) investigated size reduction and particle morphology of particles produced by milling at ambient temperatures, cool milling and cryo-milling using a ball mill, starting at sizes of …

The pyrolysis method of both raw and recycled polyethylene terephthalate was studied using the nonisothermal thermogravimetric analysis (TGA) at different five heating rates (10, 15, 20, 25, and 30 K/min) for each element. Without using any mathematical equations, the kinetic parameters of polyethylene terephthalate pyrolysis …

PES material is a high temperature engineering thermoplastic that can withstand high temperatures over long periods of time. The chemical abbreviation for polyethersulphone has long been PES. However, due to current standards such as EN ISO 1043:2011, polyethersulfones are now referred to as PESU in order to better assign them to the …

It is shown that wet grinding of polymers in a stirred media mill and organic solvents (ethanol, hexane) at reduced temperatures down to − 80 °C is a suitable method to produce polymer particles of mean diameter smaller than 5 μm with narrow particle size distribution. Results are presented for wet grinding of polystyrene (PS) and ...

A combination of 225 µm PET and 35 µm PE resulted in an increased OTR of 18.62 cm 3 /(m 2 ·day·bar) while the WVTR decreased to 1.36 g/(m 2 ·day) as PE is less permeable to moisture than PET alone but more readily transmits oxygen due to differences in the polarities of PET and PE (McKeen, 2011).

The glass transition temperature (Tg) is a phenomenon of amorphous polymers. At this temperature, polymers undergo a transition from glassy to rubbery state. Tg is an important feature of polymer behavior. It marks a region of dramatic changes in the physical and mechanical properties. Below Tg: Due to lack of mobility, the polymers are hard ...
