Compared with other materials, what are the functional characteristics of plastics?

1. Light weight: Plastic is a lighter material, and the relative density is scattered between 0.90-2.2. Obviously, can the plastic float on the water? Especially foamed plastics, because of the micropores inside, the texture is lighter, and the relative density is only 0.01. This characteristic makes plastics useful in the production of products that require reduced weight. 50 liter plastic bucket

 2. Excellent chemical stability: Most plastics have excellent anti-corrosion ability to acid, alkali and other chemical substances. Especially the polytetrafluoroethylene (F4) commonly known as the plastic king, its chemical stability is even better than that of gold, and it will not deteriorate after being cooked in "aqua regia" for more than ten hours. Because F4 has excellent chemical stability, it is an ideal corrosion-resistant material. For example, F4 can be used as the material for transporting corrosive and viscous liquid pipelines.

 3. Excellent electrical insulation function: Ordinary plastics are poor conductors of electricity, and their surface resistance and volume resistance are very large, which can be expressed by numbers up to 109-1018 ohms. The breakdown voltage is large, and the dielectric loss tangent is very small. Therefore, plastics are widely used in the electronics industry and machinery industry. Such as plastic insulated control cables.

 4. It has the function of noise reduction and shock absorption: Generally speaking, the thermal conductivity of plastic is relatively low, which is equivalent to 1 / 75-1 / 225 of steel. The micropores of foam contain gas. Shock resistance is better. 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 ability, single glass plastic windows are 40% higher than single glass aluminum windows and 50% higher than double glass. After combining the plastic form with the hollow glass, it can be used in residences, office buildings, wards, and hotels. It saves heating in winter and air-conditioning expenses in summer. The benefits are very significant.

 5. Wide spread of mechanical strength and high specific strength: some plastics are strong like stone and steel, and some are soft like paper and leather; from the mechanical functions of plastic hardness, tensile strength, elongation and impact strength, The spread is wide, and there is a lot of use to choose. Because plastic has a small specific gravity and high strength, it has a high specific strength. Compared with other materials, plastics also have significant shortcomings, such as easy burning, less rigidity than metals, poor aging resistance, and heat resistance.

  The functional characteristics of the plastic introduced above are compared with other materials, and I hope to help you. Plastic drums are mostly used for the storage and transportation of various liquids. They have outstanding characteristics for special dangerous goods packaging. They are not fragile, rust-proof, light-weight, and have excellent oil resistance and strong corrosion resistance. They are mostly used for demand. Dangerous goods packaging with thermal insulation, moisture resistance, pressure resistance and corrosion resistance.
