What are the performance and characteristics of plastic garbage bags

1. The garbage bag is light in weight

Plastic is a lighter material with a relative density of 0.90-2.2. Obviously, plastic can float on the water? Especially foam

 plastic, due to the micropores inside, the texture is lighter and the relative density is only 0.01. This feature allows plastic

 to be used in the production of products that need to reduce their own weight.

2. Excellent chemical stability of garbage bags

Most plastics have good corrosion resistance to chemicals such as acids and alkalis. In particular, polytetrafluoroethylene (F4), 

commonly known as the king of plastics, has a more stable chemical property than gold and will not deteriorate even if 

boiled in "aqua regia" for more than ten hours. Due to its excellent chemical stability, F4 is an ideal corrosion-resistant

 material. For example, F4 can be used as a material for conveying corrosive and viscous liquid pipelines.

3. Excellent electrical insulation properties of garbage bags

Ordinary plastics are poor conductors of electricity, and their surface resistance and volume resistance are large, with 

a number of up to 109~1018 ohms. The breakdown voltage is large and the dielectric loss tangent is small. Therefore,

 plastics are widely used in the electronics industry and the machinery industry. Such as 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 foam plastics. Containing gas, it has good heat insulation, sound insulation, and earthquake resistance.

 For example, the thermalconductivity 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 plastic windows are combined with hollow glass, they can be used 

in residences, office buildings, wards, hotels, etc., saving heating in winter and air conditioning costs in summer, and

 the benefits are very obvious.

5. The mechanical strength of garbage bags is widely distributed and has higher specific strength

Some plastics are as hard as stone and steel, and some are as soft as paper and leather. From the perspective of 

mechanical properties such as hardness, tensile strength, elongation, and impact strength of plastics, they have a

 wide distribution range and many options for use. Because plastic has a small specific gravity and high strength, 

it has a high specific strength. Compared with other materials, plastic also has obvious disadvantages, such as 

flammability, higher rigidity than metal, poor aging resistance, poor heat resistance, etc.
