This technical note provides a basic resistance rating for … HDPE, which stands for high-density polyethylene, is a versatile plastic known for its unique benefits. Polyethylene is a kind of thermoplastic polymers, which means that it turns into liquid by reaching its melting point and turns into solid by reaching its freezing point. Aq. In terms of machining, HDPE finishes a … The result is a plastic that possesses impact resistance, tensile strength and resistance to fracture that linear polyethylene can’t match. Poor resistance, not recommended. The chemical formula of polypropylene is (C3H6)n. PP … In general, the less compounding components used the better the chemical resistance. It also offers a high chemical resistance. They are unaffected by most inorganic acids, alkalis, and aqueous solutions which rapidly corrode metals, although some concentrated acids and oxidizing agents can attack them, especially at elevated temperatures. It lends itself particularly well to blow molding. PET bottles are temperature resistant up to 145°F.Both HDPE and PET are great for various applications both inside and outside the laboratory as they are inert and have good chemical resistance. The following is an illuminating article on Polypropylene vs abs, ... ie it is a thermoplastic . These qualities make cross-linked polyethylene an excellent choice when tank integrity is critical. If you need a container that’s more durable and temperature resistant, HDPE is the plastic of choice. Softening, loss of strength, swelling may occur. See under Allyl, Amyl, Butyl, Ethyl, Furfuryl, Methyl, or iso-Propyl 2. • C = Fair -- Moderate Effect, not recommended for continuous use. The information below concerns general polyethylene chemical resistance only. Negligible effect on mechanical properties. Polypropylene is a tough and rigid, crystalline thermoplastic produced from propene (or propylene) monomer. HDPE (High Density Polyethylene) has a somewhat lower tensile strength than UHMW. Chemical Resistance for Plastics - Find plastic materials and their resistance to different chemicals. > Styrenic Plastic Up Two > ABS Up One.

Satisfactory to 120°F (48°C) Ratings -- Chemical Effect • A = Excellent. Chemical Resistance Chart for HDPE (High Density Polyethylene) The chemical resistance chart below is a general guide only. Have a question on the chemical resistance of plastics? Chemical Resistance Chart; Legend. The specific gravity is 0.91 compared to 1.4 for PVC. It’s abrasion resistance is good, much better than that of PVC. The difference between polyolefin and polyethylene is that polyolefin is made from the polymerization of alkenes whereas polyethylene is made from the polymerization of ethylene molecules. These raw materials have outstanding resistance to both physical and chemical attack. Summary – Polyolefin vs Polyethylene. Limited resistance, moderate attack, suitable for short term use only. Good resistance, minor attack. It depends on the requirement of the packing for the product whether for food items or for other use. High Density Polyethylene is a rigid, tough and strong resin of natural milky color. PE - Polyethylene - Chemical Resistance - Chemical resistance of Polyethylene - PEH - to common products; Plastic Pipes - Friction Head Loss - Friction head loss (ft/100 ft) in plastic pipes - PVC, PP, PE, PEH; Polyester - Chemical Resistance - Chemical resistance of Polyester to products like Acetic acid, Diesel oil and others Acetaldehyde LDPE and HDPE at 20C° show little or no damage after 30 days of constant exposure. HDPE and LDPE Resistance Chart by Chemical LDPE & HDPE resistance listed by chemical 1.4-dioxane LDPE and HDPE at 20C° show little or no damage after 30 days of constant exposure. It’s among the most commonly used plastics worldwide, and in addition to UV resistance, has a variety of useful traits. HDPE is used in a variety of applications and industries where impact resistance, high tensile strength, low moisture absorption and chemical and corrosion resistance properties are required.

Thermoplastic pipes with significant filler percentages may be susceptible to chemical attack where an unfilled material may be affected to a lesser degree or not at all. A = No Attack, possibly slight absorption. However, HDPE can remain flexible as well. Polyvinyl Chloride (PVC) Polyvinyl Chloride is a widely-used plastic. LDPE at 50C° shows some effect after 7 days of constant exposure. The high-temperature properties of the polymer are improved, its flow is reduced, and its chemical resistance is enhanced. Since other factors such as permeation, ESCR, and container design are involved, full compatibility testing is recommended. Thanks to the material’s extreme strength, HDPE is commonly used to create containers like milk and water jugs, where a 60g jug can effectively retain over a gallon of liquid without distorting its original shape. HDPE has very good stress crack resistance as well as high impact and melt strength. PP plastic offered remarkable chemical resistance, purity, and it is the only one light weight polymer when compared to all conventional plastics. Nowadays, PP provides innovative solutions for many drawbacks came from automotive industry. If you require a crystal-clear container and can't use glass, reach for the PET container.
