Propelled leaf
Polypropylene is a white or gray solid substance, a plastic polymer with a wide range of applications. Today, it is the most sought-after modern plastic, thanks to its excellent consumer properties and versatility of use.
Basic physical properties
• Low material density. Polypropylene has the lowest density of all plastics, which favorably distinguishes it from denser analogues.
• High strength. Numerous experiments have shown that it withstands a greater load, which far exceeds the capabilities of polyethylene.
• Resistance to low temperatures. The polymer perfectly copes with negative temperatures, withstanding - 10 degrees Celsius and lower temperatures.
• Resistance to high temperatures. It withstands not only low, but also high temperatures, its melting point is 160-170 degrees Celsius.(//tractor-service.com)
• Resistance to sudden temperature changes. This material is also not afraid of a rapid change in temperature. It withstands the rapid transition from minus to plus and back.
• Excellent dielectric properties. High dielectric constant together with high dielectric strength provide wide possibilities of its application as an electrical insulating material.
• Easy handling. Polypropylene is easily welded, sawed, drilled, bends well, which significantly expands the possibilities of its application in industry and everyday life.
Chemical characteristics
• Resistance to chemical aggression. This feature of the material allows it to be widely used for the needs of chemical enterprises. It withstands the effects of red-hot metal, various acids and is vaporized. In particular, this property is used in the manufacture of air ducts and ventilation for hazardous industries.
• Environmental friendliness and safety for the environment and people. Numerous experiments have proven the non-toxicity and absolute environmental safety of this material for the environment and humans. Therefore, it is used in the production of containers for water, as well as various liquids and bulk food products. Very often it is used in the construction of structures for water purification.
