1. The garbage bag is lightweight
Plastic is a lighter material with a relative density of 0.90-2.2. Obviously, can plastic float on the water surface? In particular, the foam plastic has a light texture and a relative density of only 0.01 due to the micro pores inside. This feature allows plastic to be used in the production of products that require weight reduction.2. Excellent chemical stability of garbage bags
Most plastics have good corrosion resistance to chemicals such as acids and bases. Especially polytetrafluoroethylene (F4), commonly known as the king of plastics, has more stable chemical properties than gold, and even if boiled in aqua regia for more than ten hours, it will not spoil. Due to its excellent chemical stability, F4 is an ideal corrosion-resistant material. For example, F4 can be used as a material for transporting corrosive and viscous liquids in pipelines.3. Excellent electrical insulation performance of garbage bags
Ordinary plastic is a poor conductor of electricity, with high surface and volume resistance, ranging from 109 to 1018 ohms. The breakdown voltage is high, and the tangent value of the dielectric loss angle is small. Therefore, plastics have a wide range of applications in the electronics and machinery industries. Like plastic insulated control cables.
4. Garbage bags have poor thermal conductivity and have noise reduction and shock absorption effects
Generally speaking, the thermal conductivity of plastics is relatively low, equivalent to 1/75-1/225 of steel, and the micropores of foamed plastics. Containing gas, it has good insulation, sound insulation, and seismic performance. For example, the thermal conductivity of polyvinyl chloride (PVC) is only 1/357 of steel and 1/1250 of aluminum. In terms of thermal insulation capacity, single glass plastic windows are 40% higher than single glass aluminum windows, and double glass windows are 50% higher. After combining plastic windows with insulating glass, they can be used in residential, office buildings, wards, hotels, etc., saving heating costs in winter and air conditioning costs in summer, with significant benefits.5. The mechanical strength distribution of garbage bags is wide, with higher specific strength
Some plastics are as hard as stones and steel, while others are as soft as paper and leather. From the mechanical properties such as hardness, tensile strength, elongation, and impact strength of plastics, their distribution range is wide, and there are also many choices for use. Due to its small specific gravity and high strength, plastic has a high specific strength. Compared with other materials, plastics also have obvious drawbacks, such as flammability, higher stiffness than metals, poor aging resistance, and poor heat resistance.
