EPS (Expanded Polystyrene) is an extremely lightweight product that is made of expanded polystyrene beads. Originally discovered by Eduard Simon in 1839 in Germany by accident, EPS foam is more than 95% air and only about 5% plastic. Small solid plastic particles of polystyrene are made from t...
@Oceana – Polystyrene will deteriorate if it isn't sandwiched between protective layers. If it starts to come apart, then the work of art it holds will be vulnerable to bending. The safest polystyrene to use is foam board. It is covered on front and back, and you can get an acid free...
Ethylene (PE Wax), also known as low molecular weight polyethylene, is formed by the polymerization of ethylene monomers or the cracking of PE resin. It appears as small white beads or flakes, with high melting point, low viscosity, high gloss, and good hardness, providing lubrication, demoldi...
An egg carton is a cardboard, plastic, or polystyrene container used to hold and transport eggs. Egg cartons are also often used...
and divinylbenzene as the cross-linking agent to synthesize a A series of hydrophobic and highly microporous cross-linked polystyrene adsorbent resins. In the process of treating waste gas containing volatile organic compounds, the adsorption performance of the adsorbent is minimally affected by moisture...
The outer “shell” can be made of fabric, leather, knitted material and more. Despite the name, bean bags are usually not actually filled with beans, or in some cases, dried peas or millet. Rather, they are usually filled with man made materials such aspolystyrenebeads or ground Styrofoam...
There often are tiny bits of plastic in the fish and shellfish we eat. Scientists are racing to figure out what that means for our health.
Some highly filled mineral compounds can cause abrasive wear in injection molds or extruders, depending on the filler, the filler’s loading, and the processing conditions and metals used to make the tooling. Some minerals are harder and more abrasive than others. ...
resulting in the polystyrene beads becoming filled with cavities containing boiling pentane, expanding each bead in size by around 4000 percent. The pentane liquefies as it cools, leaving air-filled bubbles throughout each bead. The expanded beads are then fed into a mold to be pressed together...
(1.59) can be significantly different than a cell’s, resulting in very different scatter signals between a bead and a cell of the same diameter. Given the fact that cells are composed of much more water than a polystyrene bead is and that water’s RI is 1.333, polystyrene beads a...
