Structural plastic are a type of plastic that can be used as structural materials. They have high strength, even comparable to steel. Such plastic include, but are not limited to, fiberglass reinforced plastic.
Polytetrafluoroethylene (PTFE) is a heavy plastic with a density of about 2.1~2.29g/cm3. It is highly stable and corrosion-resistant and can withstand extreme high and low temperature environments. This property makes polytetrafluoroethylene widely used in bridges, buildings and other fields, especially in load-bearing bearings.
Polyoxymethylene is a plastic with good comprehensive properties, featuring high strength, high stiffness, and excellent wear and chemical resistance. With the advancement of processing technology, the strength and modulus of polyoxymethylene have approached those of steel, making it an ideal choice for building support materials.
Nylon is known for its excellent mechanical properties and weather resistance. It is suitable for the production of a variety of building components, such as window frame buffer supports, door pulleys, etc. In recent years, in order to achieve better thermal insulation effect, nylon 66 has been used to manufacture bridge-type thermal insulation window frames.
Structural foam is a foam with different degrees of foaming in the inner and outer layers. This special foam can be produced through specific molding technology and processing techniques, such as co-injection, co-extrusion, etc.
Structural plastic are widely used in the construction field, especially in situations where high load-bearing capacity is required. Although large unreinforced solid polymer parts are uncommon due to their low stiffness, these materials still have some application value in some special cases such as window glass, roof tiles and veneer panels. In addition, novel applications of thermoplastic have also promoted the development of various building accessories such as window frames, reinforced partitions, etc.
Fire safety is an important consideration in the application of structural plastic.
