Is there any difference between PE filter bag and PP filter bag?
Is there any difference between the PE filter bag and the PP filter bag? It must be known that there are great differences between the PP material and the PE material.
Pp filter bags are widely used, such as cosmetics. The advantages of pp filter bag are environmental protection, no pollution to the environment, and good thermal insulation performance. It can be directly used to package goods without any processing work. Therefore, it is very suitable for filtering some items or drinks with high environmental requirements. However, pp material has a big disadvantage that it is not resistant to high temperature. When the temperature reaches above 50 ℃, it will decompose into toxic compounds, so it is widely used as a container sealing material in plastic containers. However, this material also has a disadvantage: it is easy to age, especially in damp and sunlight, which will accelerate the attenuation of performance, especially in the application of plastic products.
PE filter bag is a thermoplastic resin prepared by polymerization of ethylene. Its characteristics: corrosion resistance, excellent electrical insulation (especially high frequency insulation), chlorination, chemical cross-linking, irradiation cross-linking modification, and glass fiber reinforcement. Low pressure polyethylene has high melting point, rigidity, hardness and strength, low water absorption, good electrical performance and radiation resistance; High pressure polyethylene has good flexibility, elongation, impact strength and permeability; UHMWPE has high impact strength, fatigue resistance and wear resistance. Low-voltage polyethylene is suitable for making corrosion-resistant parts and insulating parts; High pressure polyethylene is suitable for making films, etc; UHMWPE is suitable for making shock absorption, wear resistance and transmission parts.
