 Material Properties

FeaturePP (Polypropylene) ChairPC (Polycarbonate) Chair
StrengthModerate, flexibleVery high, rigid
Impact ResistanceGood, but can crack under extreme forceExcellent, nearly unbreakable
Heat ResistanceModerate (softens at ~100°C)High (withstands ~120-130°C)
UV ResistancePoor (can degrade in sunlight)Excellent (UV-stabilized options available)
WeightLightweightHeavier than PP
FlexibilityMore flexible, can bendRigid, less prone to deformation
PP Plastic (Polypropylene):

PP is a high molecular polymer that features good toughness, wear resistance, and chemical stability. It has a high melting point and is not prone to deformation. Additionally, it is relatively inexpensive. Chairs made of PP are typically lightweight and water-resistant. However, they have lower hardness and insufficient flexibility, which may lead to discomfort during prolonged use.
PC Plastic (Polycarbonate):

PC is an engineering plastic known for its high strength, toughness, transparency, and weather resistance. It also has excellent heat and chemical resistance. Chairs made of PC are usually more robust and durable, with high hardness and resistance to deformation. However, they are more expensive and have complex manufacturing processes.

Durability & Longevity

PP Chairs:

  • Prone to scratching and wear over time.

  • May become brittle in cold temperatures.

  • Cheaper but may need replacement sooner.

PC Chairs:

  • Extremely durable, resistant to cracks and breaks.
  • Better for outdoor use (if UV-stabilized).
  • Long lifespan, often used in high-traffic areas.

 Comfort & Design

PP Chairs:

  • Often molded into ergonomic designs.
  • Softer feel but may sag over time.
  • Available in bright colors but may fade.

PC Chairs:

  • Harder surface, less flexible.
  • Can be transparent or opaque (common in modern designs).
  • Retains shape better under weight.

Applicable Scenarios

PP Plastic Chairs:
Due to their low cost, light weight, and good wear resistance, PP plastic chairs are more suitable for general households, offices, and outdoor use. For example, in restaurants, living rooms, and outdoor barbecue areas, PP chairs are popular for their durability and cost-effectiveness.
PC Plastic Chairs:
PC plastic chairs, with their high strength, impact resistance, and aesthetic appeal, are more suitable for high-end business settings, long-term use scenarios, or environments requiring higher quality. For instance, in high-end restaurants, hotels, or meeting rooms where prolonged sitting is required, PC chairs can provide better comfort and stability.

Overall, both PP plastic chairs and PC plastic chairs have their own strengths and limitations. If the budget is limited and comfort requirements are not high, PP plastic chairs are a good choice. However, if durability, comfort, and a high-end appearance are prioritized, PC plastic chairs should be considered first. Consumers can select the appropriate material based on their own needs and usage scenarios.
