2. Polypropylene - Wikipedia

   en.wikipedia.org/wiki/Polypropylene

   Polypropylene belongs to the group of polyolefins and is partially crystalline and non-polar. 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]

3. List of synthetic polymers - Wikipedia

   en.wikipedia.org/wiki/List_of_synthetic_polymers

   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. Properties depends on the form, expanded form is tough and rigid: Petri dishes, CD case, plastic cutlery

4. List of materials properties - Wikipedia

   en.wikipedia.org/wiki/List_of_materials_properties

   A material property is an intensive property of a material, i.e., a physical property or chemical property that does not depend on the amount of the material. These quantitative properties may be used as a metric by which the benefits of one material versus another can be compared, thereby aiding in materials selection.

5. 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]

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. 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).

9. Crystallization of polymers - Wikipedia

   en.wikipedia.org/wiki/Crystallization_of_polymers

   Crystallization affects optical, mechanical, thermal and chemical properties of the polymer. The degree of crystallinity is estimated by different analytical methods and it typically ranges between 10 and 80%, with crystallized polymers often called "semi-crystalline". The properties of semi-crystalline polymers are determined not only by the ...
