2. Polypropylene - Wikipedia

   en.wikipedia.org/wiki/Polypropylene

   Polypropylene is normally tough and flexible, especially when copolymerized with ethylene. This allows polypropylene to be used as an engineering plastic, competing with materials such as acrylonitrile butadiene styrene (ABS). Polypropylene is reasonably economical. [citation needed] Polypropylene has good resistance to fatigue. [8]: 3070

3. List of synthetic polymers - Wikipedia

   en.wikipedia.org/wiki/List_of_synthetic_polymers

   The plastic kits and covers are mostly made of synthetic polymers like polythene, and tires are manufactured from polybutadienes. [1] However, due to the environmental issues created by these synthetic polymers which are mostly non-biodegradable and often synthesized from petroleum, alternatives like bioplastics are also being considered. They ...

4. Polypropylene drum - Wikipedia

   en.wikipedia.org/wiki/Polypropylene_drum

   Polypropylene is a semi-crystalline thermoplastic with high bonding strength, tough, stable, elastic, hard and highly abrasion- and impact-resistant. Because of its chemical and physical molecular structure, solid masses of polypropylene are highly resistant to a wide range of aggressive chemicals including aqueous solutions of salts, acids and ...

5. Plastic - Wikipedia

   en.wikipedia.org/wiki/Plastic

   The development of plastics has evolved from the use of naturally plastic materials (e.g., gums and shellac) to the use of the chemical modification of those materials (e.g., natural rubber, cellulose, collagen, and milk proteins), and finally to completely synthetic plastics (e.g., bakelite, epoxy, and PVC).

6. Thermoplastic olefin - Wikipedia

   en.wikipedia.org/wiki/ThermoPlastic_Olefin

   The PP and PE components of a blend constitute the "crystalline phase", and the rubber and branched PE chains and PE/PP end groups gives the "amorphous phase". If PP and PE are the dominant component of a TPO blend then the rubber fraction will be dispersed into a continuous matrix of "crystalline" polypropylene.

7. 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]
