Technical Properties of Laminated High Density Polyethylene [HDPE] Corrugated
Typical Physical Properties
(a) Thermal Expansion Coefficient (ASTM D 696): 13 x 10–5 oC-1
(b) Water Absorption at 24 hours immersion (ASTM D 648): 0.02%
(c) Melting Temperature (DSC method): ~ 130oC
(d) Water Vapor Transmission Rate (WVTR) at 23oC (ASTM C 209):
WVTR, g/(cm2 x hr) = 8.3 x (p1 – p2) / l
Where p1 and p2 are the partial pressures of water vapor in Pascal at the two exposed
surfaces of IntePro and l is the total thickness of the two skin layers
(e) Coefficient of Friction (COF, ASTM D 1894): ~ 0.30 along the flute direction.
Typical Chemical Properties
(a) FDA Status: The based resin material of polyethylene meets the requirements of
the Food and Drug Administration, 21 CFR 177.1520, for a resin that may be processed
for use involving contact with food.
(b) Chemical Resistance: PE profile sheet is resistant to dilute acids, caustic liquors, solvent, alcohol, gasoline and water. Fats and oils cause only limited swelling. PE profile sheet is not resistant to oxidizing acids, ketones, aromatic hydrocarbons, chlorinated hydrocarbons and some type of detergents. These substances combined with internal stress incur mechanical or manufacture stress can lead to stress cracking. PE profile sheet is also resistant to the attack by microorganisms.
(c) pH value: PE profile sheet is inert and hydrophobic. Therefore, PE profile sheet generally does not affect the pH factor when it is in contact with an aqueous solution.
Typical Mechanical Properties
(a) Mullen Burst (TAPPI-810): no burst up to 1,000 psi for all thickness
(a) Polyethylene profile sheet is fully recyclable. The resin identification code (RIC) of
polyethylene according to Society of the Plastics Industry (SPI).
(b) If recycling is not possible, disposal to landfills or incineration in accordance with
governmental laws and regulations is considered safe.
(a) Ultra Outdoor Weather Resistant PE: Natural color polyethylene ultra outdoor weather resistance sheet was tested in a weatherometer according to SAE J1960 for 7,500 hours, which corresponds to 3 year in Miami, FL, without brittleness. The outdoor weather resistance relates to the color, temperature, application environment, etc., users are strongly recommended to make their own tests and evaluation.
