At ourinjection moldingandthermoforming company, we often use additives in thermoplastic materials to get the exact results our customers need. One type of additive that is used most often in plastic manufacturing is called a plasticizer, but what exactly do they do and what are they made of?
根据第四段 “The players were given memory and learning tests, and took a form of MRI scanning (扫描), which can examine the brain structure by recording the movement of water molecules(分子) through the tissue. They then took the same tests again two years later.(参与者接受了记忆和学习...
When the plastic film dissolves in water, it doesn’t break down the structure of the PVA molecules. The little bits of plastic from the PVA molecules now float around the water. This is the very definition of microplastics which have grave consequences for aquatic life. So can PVAtrulybe c...
HDPE is a type of polyethylene that is made from the natural gas ethane. When ethane is heated to 1500 degrees Fahrenheit, the molecules break apart. One of the new molecules formed is ethylene. Ethylene is a gas that becomes a resin during the process of polymerization. A polymer is a c...
The heroes of our story were conceived in this oil refinery. The plastic in their bodies was formed by chemically bonding oil and gas molecules together to make monomers. In turn, these monomers were bonded into long polymer chains to make plastic in the form of millions of pellets. Those ...
Heat is then applied to ethane and propane, resulting in a process known as "cracking," which transforms them into ethylene and propylene, respectively.Plastics are polymers, which means that they are created by joining together chains of molecules (known as monomers) to form a larger molecule ...
Polyolefins are used in a wide variety of applications where lightweight construction, high tensile strength, puncture resistance, chemical resistance and excellent clarity are required. In the automotive industry, polyolefin plastic materials play an essential role in fuel efficiency due to their light ...
The resulting acid consists of lactide molecules, which bond into long chains called polymers. At the end of this process, bioplastics producers have pellets of polylactic acid plastic, which can then be spun off into fibers or melted to take just about any form. One you've removed corn ...
When the electric discharge is very strong, collisions of high velocity electrons with molecules of gas result in no loss in momentum, and electron avalanching occurs. When a plastic part is placed in the discharge path, the electrons generated in the discharge impact the surface with energies ...
Nylon is the component of many plastic materials we will use in our daily lives. The structure of nylon is considered polyamides because it is made up of amide groups. The amide groups are important to consider in determining the intermolecular forces of attraction present in nylon. The ...
