The first plastic chairs were made by heating the beads to about 220 degrees Celsius and then injecting the molten substance into the mold. The gate of the die is usually located at the seat to provide fluid flow to all areas of the piece.

What kind of plastic materials are used for the chair?

Plastics were created due to the increasing scarcity of raw materials due to industrialization. New solutions are required as the market evolves and production increases. Therefore, the original researchers and creators focused their efforts on recreating existing rare and expensive materials such as mother-of-pearl, ivory, exotic woods and expensive natural stones such as granite and onyx.


A wide and diverse range of uses quickly emerged, allowing money to be invested in the research and innovation of low-cost materials such as mass-produced plastics. As a response, the focus is on enhancing the usefulness and properties of the material such as corrosion and wear resistance, excellent thermal stability and durability.

Plastic is an indispensable material in the furniture industry and the types of plastic used to make plastic tables and chairs are also increasingly improved.

Materials for the production of plastic chairs include:

  • Polythene
  • Polypropylene
  • Nylon
  • Acrylic
  • PVC and uPVC
  • Polythene
  • Bakelite
  • Polypropylene
  • Melamine
  • Epoxy
