Wulong Office Chair Materials
The material selection for office chairs in Wulong covers multiple parts including plastics, hardware, seat cushions, wooden panels, fabrics, and inner frame structures, with the characteristics of each part as follows:
Plastic parts typically use high-quality PA+ material, which is a modified new material of nylon. This material has high toughness, is not prone to breakage, and possesses excellent heat resistance, wear resistance, and anti-aging properties, ensuring stable performance of the office chair during long-term use.
For hardware parts, it is recommended to use high-quality Q235 carbon steel with a thickness specification of 20.532.5T1.5mm. This steel has a tensile strength of up to 490MPa and a yield strength of approximately 235MPa, providing strong load-bearing capacity and a high safety factor, offering stable support for the office chair.
The seat cushion part adopts high-resilience shaped foam, which has a high density and can be adjusted in hardness according to different usage scenarios. More importantly, this foam does not contain harmful substances such as IPB material or lime powder, ensuring the health of users.
The wooden panel part selects E0/E1-grade environmentally friendly plywood, which is bonded with environmentally friendly water-based glue and undergoes anti-insect treatment. This material not only has excellent environmental performance but also effectively safeguards indoor air quality and human health.
The fabric part uses DuPont nylon filament elastic mesh, which is high in weight and elasticity, capable of maintaining the shape and structural stability of the chair back. At the same time, it has strong breathability, effectively wicking away sweat and maintaining ventilation, providing a comfortable sitting experience for users.
The inner frame structure part features a variety of materials. Engineering plastics are the mainstream choice for mid-to-low-end popular office chairs, often using materials such as polypropylene (PP) and nylon (PA). They have simple molding processes and low costs but limited load-bearing capacity, suitable for daily light-load usage scenarios. Metal materials are commonly used in mid-to-high-end ergonomic office chairs, with cold-rolled welded steel pipes having the strongest load-bearing capacity and undergoing anti-rust treatments such as electrophoretic coating and powder coating on their surfaces. Aluminum alloys combine lightweight properties with excellent anti-rust and corrosion resistance. Fiberglass-reinforced plastic (FRP) is used in some high-end office chairs, offering both high strength and lightweight advantages, as well as corrosion resistance, but with relatively high production costs and lower popularity.
