Imported PP polypropylene filament non-woven fabric is a new type of material made of polypropylene as raw material, which is polymerized into a mesh through high-temperature drawing and then hot-rolled.
Let’s find out today.
Polypropylene is a polymer formed by the addition polymerization of propylene.
It is a white waxy material with a transparent and light appearance.
The density is 0.89~0.91g/cm3, it is flammable, the melting point is 165℃, it softens at about 155℃, and the use temperature range is -30~140℃.
It can withstand the corrosion of acid, alkali, salt liquid and various organic solvents below 80℃, and can decompose under high temperature and oxidation.
Polypropylene is widely used in the production of clothing, blankets and other fiber products, medical equipment, automobiles, bicycles, parts, transportation pipelines, chemical containers, etc., and is also used in food and pharmaceutical packaging.
In view of the poor impact resistance of polypropylene at low temperatures, poor weather resistance, poor surface decoration, and the gap between its functionality and actual needs in terms of electricity, magnetism, light, heat, combustion, etc., the imported PP polypropylene long Modification of silk non-woven fabrics has become the most active field of plastic processing development and the most fruitful results.
Through copolymerization modification, cross-linking modification, grafting modification, adding nucleating agent, etc., the polymer components of PP (polypropylene) can be changed to the macromolecular structure or crystal configuration to improve its mechanical properties, durability and durability. thermal properties, aging resistance and other properties to improve its comprehensive performance and expand its application fields.
Imported PP polypropylene filament non-woven fabrics for sale can be widely used in air filtration, packaging materials, medical tapes, cable wrapping, biofilms and other fields.
