Polypropylene: PP Polystyrene: PS Low-density polyethylene: LDPE Properties of Plastics The properties of plastics depend on the chemical composition of the subunits, the arrangement of these subunits, and the processing method. All plastics are polymers but not all polymers are plastic. Plastic polym...
Thermoplastic polymersor thermosoftening plastics are the other type of synthetic polymers. While thermoset plastics are rigid, thermoplastic polymers are solid when cool, but are pliable and can be molded above a certain temperature. While thermoset plastics form irreversible chemical bonds when cured, ...
In the embodiment described, the pressure roller is provided with a relief pattern and the two rollers 6 and 7 and the support roller are water cooled, the web material may be crepe paper and the plastics material polyethylene, polypropylene, polyamide or an ionomer.ARJAS A...
phthalates, dioxins, PFAS, VOCs and heavy metals as an alternative to PVC-coated fabrics for the hospitality industry. The outdated unsustainable flexible PVC plastics are used in numerous industries from billboards to sports equipment. Renegade has exclusive rights to a polypropylene-based replacement...
Even so, some crosslinking may be present to maintain a given orientation, such as desired in permanent press clothing. While most fibers are made from condensation polymers, new treatments allow some fibers to be made from olefinic materials such as polypropylene (Table 3). ...

Plastics such as polystyrene (polymerized styrene, CH2=CHC6H5), polyethylene (polymerized ethylene, CH2=CH2), or polypropylene (polymerized propylene, CH2=CHCH3) are molded into a wide variety of everyday and specialized products—for instance, eating utensils, coffee cups, synthetic fabrics, park...
A bioplastic is a moldable plastic material made up of chemical compounds that are derived from or synthesized by microbes such as bacteria or by genetically modified plants. Unlike traditional plastics, they are obtained from renewable resources.
Major industrial polymers, chemical compounds used in the manufacture of synthetic industrial materials. In the commercial production of plastics, elastomers, man-made fibres, adhesives, and surface coatings, a tremendous variety of polymers are used. Th
The alkane CH3(CH2)388CH3, in which 390 carbon atoms are bonded in a continuous chain, has been synthesized as an example of a so-called superlong alkane. Several thousand carbon atoms are joined together in molecules of hydrocarbon polymers such as polyethylene, polypropylene, and polystyrene....
