What is the main difference between PU tube and PE trachea?

PE material is polyethylene, is the largest amount of plastic materials, it is a polymer material synthesized from polyethylene. High density polyethylene (HDPE.PE) materials are divided into five grades according to the international standard: PE32 grade, PE40 grade, PE63 grade, PE80 grade and PE100 grade. They are classified into two categories: low density polyethylene (LDPE), low strength polyethylene (low strength) and high density polyethylene (HDPE). The production of PE pipe for water supply pipe is high density polyethylene (HDPE,), and its grade is two kinds of PE80,PE100 (according to minimum strength Minimum Required Strengt). H abbreviation MRS) .PE80 MRS up to 8 MPA / PE100 MRS up to 10MPa.MRS refers to the circumferential tensile stress intensity of the tube (calculated according to international standards).
There are acid-resistant PU, but PVDF will be better, there are special requirements to recommend the use of this type
Characteristics of PU trachea
1, plastic polyamine resin material, in line with ROHS environmental protection requirements; 2, high elasticity: small bending radius to enable PU pipe to pass through the dense space; 3, anti-knotting: better than other plastic pipe anti-knotting effect; (4) variable resilience: tolerable retractable; 5, anti-wear: long service life, suitable for wear-prone environment; 6, low gas permeability: reduce the problem of see-through and pollution; 7, good solubility: no solvent will leak out and therefore will not pollute the environment; 8, low compressibility: maintain good physical; 9, wide resistance: certain resistance to chemicals, water, fuel, oil and bacteria.
The PU pipe has excellent high pressure resistance, vibration resistance, corrosion resistance, abrasion resistance, weather resistance, bending resistance and light weight, and the PU pipe is convenient to use and flexible, It has excellent heat-resistance and heat-insulation and excellent free-to-bend performance!
PE tube has middle density polyethylene tube and high density polyethyle
