POLIPOLEN® - PE (POLYETHYLENE) It is maintained from coke oven gas or from natural gas or from Ethene or Ethane which is produced by cracking of petroleum. Monomer, is polimerized by low pressure or high pressure method and then can be maintained as high density (PE-YY 0,941 and 0,965 g/cm³) or low (normal) density polyethylene(PE-NY 0,914 and 0,925 g/cm³). Other differences of various PE types are according to their melting degrees and  opposite proportional connection occurs according to their relative molecular weights. In other words, when its melting degree is at the lowest level, its relative molecular weight is at the highest level and e.g. its mechanical specialities are the best.        POLIPOLEN has quite a low density. Its flexibility rate is high and it is resistant to strokes even at low temperatures. It has a very high molecular weight(molecular chain length). It has a high corrosion resistance because of its high molecular chain. According to the results of the "sand slurry" corrosion test which is made as per "DIN" standarts, POLIPOLEN 1000 , has shown the highest corrosion resistance among the solid materials( e.g. steels, tree, other engineering plastics.)     Polyethylenes, among each other, are separated to the below mentioned types: 1. PE 1000: Polyethylene with very high molecular weight (UHMW - PE 1000; Ultra High Molecular Weight Polyethylene). Polyethylenes with molecular weight higher than 3 million gr/mol. 2. PE 500: Polyethylenes with molecular weight higher than  500,000 gr/mol. 3. PE 300: Pe 300 and polyethylenes with high density. 4. Polyethylenes with low density.       PROPERTIES OF POLIPOLEN® · Very high stroke resistance · Very high corrosion resistance · Very high chemical resistance · Getting lubricated itself and slicky · Excellent electrical resistance · Quietness while processing and reducing vibrations · Easy processing · Low friction rate · Very low water absorption GENERAL USAGE AREAS OF POLIPOLEN® · Coal warehouses and conveyor systems · Gutters · Chain conveyor guides · Elevators · Electric power stations · Cement industry · Lime industry · Palister industry · Food industry · Cutting and chopping plates · Chopping blocks · Conveyor screws · Sliding elements · Flat guides · Profiles · Bobbins · Star and screw conveyors · Elevator systems    · Sliding bearings · Gears · Motor landing plates · Stopper valves · Closing claps · Acid pumps · Filters   POLIPOLEN® PRODUCTS · RODS · SHEETS POLIPOLEN® CHEMICAL RESISTANCE TABLE Pure Aceton (+) Formicacid %10 + Ammonia %10 + Anone (+) %96 Ethanole + Aceton Ethele + Other Etheles + Ethylene Cloride (+) Benzole (+) Benzene (+) Tar (+) Boricacid Solution %10 + Buthy Acetate (+) Calcium Cloride %10 + Chlorbenzene - Cloraform - Citric Acid Solution + Chlophene A60 %50 + Cyclohexane + Cyclohexanone + Decaline (+) Motor Fat + Dimethyle Formamide + Dioctyle Phthalato + Dioxane (+) Acetic Acid Concentration + Acetic Acid Solution %10 + Acetic Acit Solution %5 + Hydrofluoric Acid + Formaldeid %30 + Formamide (+) Liquid Freon (+) Fruit Juice + Giyeol + Giysantin, Aqueous solution %40 + Giycerine + Urea + Hot Oil + Hegzane - Iso - Octane + Isopropanole + Lodine Solution, Alcohol Solution + Potassium Solution %50 + Potassium Solution %10 + Potassium dich.squacus sol. %10 + Potassium perm.
