2. Thermoplastic - Wikipedia

   en.wikipedia.org/wiki/Thermoplastic

   A thermoplastic, or thermosoftening plastic, is any plastic polymer material that becomes pliable or moldable at a certain elevated temperature and solidifies upon cooling. [1] [2] Most thermoplastics have a high molecular weight. The polymer chains associate by intermolecular forces, which weaken rapidly with increased temperature, yielding a ...

3. High-density polyethylene - Wikipedia

   en.wikipedia.org/wiki/High-density_polyethylene

   High-density polyethylene ( HDPE) or polyethylene high-density ( PEHD) is a thermoplastic polymer produced from the monomer ethylene. It is sometimes called "alkathene" or "polythene" when used for HDPE pipes. [1] With a high strength-to-density ratio, HDPE is used in the production of plastic bottles, corrosion-resistant piping, geomembranes ...

4. Bioplastic - Wikipedia

   Bioplastic. Biodegradable plastic utensils. Flower wrapping made of PLA-blend bio-flex. Bioplastics are plastic materials produced from renewable biomass sources, such as vegetable fats and oils, corn starch, straw, woodchips, sawdust, recycled food waste, etc. Some bioplastics are obtained by processing directly from natural biopolymers ...

5. Fibre-reinforced plastic - Wikipedia

   en.wikipedia.org/wiki/Fibre-reinforced_plastic

   Fibre-reinforced plastic ( FRP; also called fibre-reinforced polymer, or in American English fiber) is a composite material made of a polymer matrix reinforced with fibres. The fibres are usually glass (in fibreglass ), carbon (in carbon-fibre-reinforced polymer ), aramid, or basalt. Rarely, other fibres such as paper, wood, boron, or asbestos ...

6. Corrugated plastic - Wikipedia

   en.wikipedia.org/wiki/Corrugated_plastic

   Corrugated plastic is commonly used to erect commercial, political or other types of signs and for constructing plastic containers and reusable packaging. [citation needed] It is widely used in the signwriting industry for making signs for real estate sales, construction sites and promotions. [citation needed]

7. Amino acid - Wikipedia

   en.wikipedia.org/wiki/Amino_acid

   Amino acids can be classified according to the locations of the core structural functional groups ( alpha- (α-), beta- (β-), gamma- (γ-) amino acids, etc.), other categories relate to polarity, ionization, and side chain group type ( aliphatic, acyclic, aromatic, polar, etc.). In the form of proteins, amino acid residues form the second ...
