Which of the following plastics is known for its excellent chemical stability and low water absorption?
This plastic is commonly used in films, containers, and pipes.
While this plastic is durable, it's more known for heat resistance.
This plastic is known for mechanical strength and chemical resistance.
This plastic is brittle and used in packaging materials.
Polyethylene (PE) is known for its excellent chemical stability and low water absorption, making it ideal for films, containers, and pipes. Other plastics like PP, PVC, and PS have different primary properties.
What property makes Polypropylene (PP) suitable for automotive parts?
This property allows PP to be used in car parts exposed to high temperatures.
This property is associated with plastics like PC.
This is a property of Polystyrene, not PP.
Though PP has good electrical properties, this isn't its defining characteristic for automotive use.
Polypropylene (PP) is suitable for automotive parts due to its excellent heat resistance, which allows it to withstand high temperatures. Its transparency and brittleness are not relevant factors here.
Which plastic is favored in electronic casings due to its optical clarity?
This plastic offers good optical properties.
This plastic is known for high strength rather than optical clarity.
Known for toughness, not clarity.
This plastic has excellent mechanical properties but not optical clarity.
Polystyrene (PS) is favored in electronic casings due to its optical clarity. Other plastics like PC, ABS, and PVC are chosen for different reasons such as strength or mechanical properties.
Why is ABS plastic considered versatile in manufacturing?
These features make it popular in various industries.
This feature is more associated with PC.
ABS actually has good thermal properties.
While resistant, this is not the main reason for its versatility.
ABS plastic is versatile due to its ease of processing and high surface gloss. It can be easily shaped and treated, making it suitable for diverse applications. High transparency and low thermal stability are not relevant here.
What makes Polycarbonate (PC) ideal for bulletproof glass?
These properties contribute to its use in safety equipment.
Flexibility isn't the primary factor for safety applications.
Though it has some resistance, it's not the key factor here.
PC's cost isn't typically its selling point for such uses.
Polycarbonate (PC) is ideal for bulletproof glass due to its high strength and toughness. Its flexibility and chemical resistance are less significant in this context. Cost isn't the primary consideration here.
Which plastic is commonly used in making pipes due to its chemical corrosion resistance?
This plastic is known for its strong mechanical properties as well.
More commonly used in toys and packaging, not pipes.
While durable, PE isn't primarily used in piping for corrosion resistance.
ABS is more used in automotive and electronic housings than piping.
Polyvinyl Chloride (PVC) is commonly used in making pipes due to its strong chemical corrosion resistance and mechanical properties. Other plastics like PS, PE, and ABS serve different purposes.
Why might Polypropylene (PP) be chosen over Polyethylene (PE) for certain applications?
These properties make PP suitable where durability is needed.
Cost isn't necessarily the deciding factor here.
PE is typically more flexible than PP.
Both have low density, but the deciding factor is strength and stiffness.
Polypropylene (PP) might be chosen over Polyethylene (PE) due to its better strength and stiffness, making it suitable for applications requiring durability. Flexibility and cost efficiency aren't the primary reasons here.
Which industry primarily benefits from using Polyethylene (PE) for moisture-resistant packaging solutions?
This industry values PE's low water absorption properties.
Automotive typically uses PP or PC more often.
Electronics often favor PC or ABS for their properties.
While PVC might be used here, PE is not the primary choice for healthcare packaging.
The packaging industry benefits from using Polyethylene (PE) due to its low water absorption and chemical stability, making it ideal for moisture-resistant packaging solutions. Other industries like automotive and electronics prefer different materials.
