2. Polypropylene - Wikipedia

   en.wikipedia.org/wiki/Polypropylene

   Its properties are similar to polyethylene, but it is slightly harder and more heat-resistant. It is a white, mechanically rugged material and has a high chemical resistance. [1] Polypropylene is the second-most widely produced commodity plastic (after polyethylene).

3. Polyolefin - Wikipedia

   en.wikipedia.org/wiki/Polyolefin

   Polypropylene is commonly used in car bumpers, interior trims, and other components [19] where TiO₂ is added to improve the UV stability of the plastic, ensuring that parts do not degrade or lose color when exposed to sunlight over time. [20] Polyethylene films are widely used in agriculture for greenhouses, mulching, and silage wraps. [21]

4. List of synthetic polymers - Wikipedia

   en.wikipedia.org/wiki/List_of_synthetic_polymers

   Bottles, pipes, inner insulation (dielectric) of coax cable (see also PTFE), plastic bags, etc. Polypropylene: PP: Resistant to acids and alkalies, High tensile strength: Auto parts, industrial fibers, food containers, liner in bags, dishware and as a wrapping material for textiles and food Polystyrene (thermocole) PS: Thermal insulator.

5. Engineering plastic - Wikipedia

   en.wikipedia.org/wiki/Engineering_plastic

   An ABS 3D bell manufactured with a 3D printer. Engineering plastics [1] are a group of plastic materials that have better mechanical or thermal properties than the more widely used commodity plastics (such as polystyrene, polyvinyl chloride, polypropylene and polyethylene).

6. Thermoplastic - Wikipedia

   en.wikipedia.org/wiki/Thermoplastic

   Polypropylene sheets are used for stationery folders and packaging and clear storage bins. Polypropylene is defined by the recyclable plastic number 5. Although relatively inert, it is vulnerable to ultraviolet radiation and can degrade considerably in direct sunlight. Polypropylene is not as impact-resistant as the polyethylenes (HDPE, LDPE).

7. Polypropylene carbonate - Wikipedia

   en.wikipedia.org/wiki/Polypropylene_carbonate

   Polypropylene carbonate is used to increase the toughness of some epoxy resins. It is used as a sacrificial binder in the ceramic industry, which decomposes and evaporates during sintering . It has a low sodium content which makes it suitable for the preparation of electroceramics like dielectric materials and piezoelectric ceramics.
