PE board - sky blue
PE sheet: English name of the High Density Polyethylene, Chinese: Polyethylene sheet, PE sheet is a high crystallinity, non-polar thermoplastic resin. HDPE appearance of the original state was milky white, in the meager section of a certain degree of translucent.
Has excellent resistance to most of the characteristics of life and industrial chemicals. Certain types of chemicals can cause chemical attack, such as corrosive oxidants (concentrated nitric acid), aromatic hydrocarbons (xylene), and halogenated hydrocarbons (carbon tetrachloride). The polymer does not absorb moisture and has good water vapor resistance, can be used for packaging purposes. HDPE has good electrical properties, especially dielectric high dielectric strength, it is suitable for wire and cable. Medium to high molecular weight grades have excellent impact resistance, even at room temperature and at -40F low temperature are so. The unique properties of the various grades of HDPE are the proper combination of four basic variables: density, molecular weight, molecular weight distribution and additives. Different catalysts are used to produce custom-tailored specialty polymers, which combine to produce HDPE grades for different applications; achieving the best balance in performance. Has good chemical stability, can resist most of the acid, alkali, organic solution and the erosion of hot water, electrical insulation is good.
Physical and chemical data
HDPE plate (high-density polyethylene plate) melting point of about 130 ℃, the relative density of 0.941 ~ 0.960g / cm3. It has good heat resistance and cold resistance, chemical stability, but also has a high rigidity and toughness, good mechanical strength. Dielectric properties, resistance to environmental stress cracking is also better. The melting temperature of 220 ~ 260C. For larger molecular materials, the recommended melting temperature range between 200 ~ 250C.
Chinese name: polyethylene
English name: POLYETHYLENE
English name 2: PE
Molecular formula: (C2H4) n
Product specifications: Thick x wide x long 1-100mmX1000mmx2000mm
Key Features
PE sheet odorless, non-toxic, feel like wax, with excellent low temperature performance (minimum use temperature up to -70 ~ -100 ℃), chemical stability, energy
Resistance to most of the acid-base erosion (intolerance of the oxidation of acid), insoluble at room temperature in general solvents, water absorption, excellent electrical insulation properties, low density, good toughness (the same applies to low temperature conditions) ; Electrical and dielectric insulation, low water absorption, low water vapor permeability, good chemical stability, tensile strength, non-toxic harmless.
However, PE sheet for the environmental stress (chemical and mechanical action) is very sensitive, poor heat aging resistance.
Applications
Medical equipment parts, seals, cutting boards, sliding profiles. Widely used in chemical industry, machinery, chemicals, electricity, clothing, packaging, food and other industries. Widely used in gas transportation, water supply, sewage, agricultural irrigation, fine particles of solid mineral transport, and oil, chemical and telecommunications and other fields, especially in the gas transmission has been widely used.
