Polyethylene Products Low‑density linear polyethylene (LLDPE – Linear Low Density Polyethylene) is a thermoplastic used in a variety of applications. It is a semi‑permeable, pliable, and highly durable polymer that is favored in industry for its low cost and high resistance. Based on density and chemical properties, polyethylene is classified into several categories. Its mechanical properties depend on molecular weight, crystal structure, and branching type. While characteristics vary by grade, common attributes include excellent resistance to outdoor conditions and moisture, flexibility, low mechanical strength, and superior chemical resistance. Polyethylene components are used in the manufacture of slides, stairs, railings, barriers, accessories, roofs, and more. To prevent color fading, masterbatch pigments used for coloring polyethylene must have a Lightfastness value of 6 or higher. The product wall thickness must be a minimum of 6 mm (0.2 in) for sections exposed to pressure or friction, and a minimum of 4 mm (0.2 in) for barriers and shading elements that are not pressure‑exposed. Material distribution must be uniform, creating consistent thickness. Wall‑thickness tolerance is ±5%. Carrier Construction Steel tubes with a minimum 114 mm (4.5 in) diameter and at least 2 mm (0.1 in) wall thickness, conforming to TS EN 10219‑2, TS‑6476, DIN 2394 standards, will be cold‑formed and welded by high‑frequency welding within the specified tolerance, dimension, and cross‑section range. These carrier tubes will be sandblasted and then powder‑coated with a polyester‑based electrostatic powder paint. Electrostatic Powder Coating Process All metal parts will be cleaned of oil, dirt, and rust using sandblasting to create surface porosity for better paint adhesion. Fine bead material will be sprayed with pressurized air to open pores and remove contaminants before coating. After fabrication, metal components will be coated with a polyester‑based electrostatic powder and baked at 200–220 °C for 20 minutes. Subsequently, parts will undergo a 10‑minute dip in a 70 °C, 5 % concentration oil‑removal bath, followed by a 15‑minute dip in a 50 °C, 1 % concentration iron bath. After rinsing and drying, the components will receive a final polyester‑based electrostatic powder coating and be cured in ovens at 180–200 °C for 20–30 minutes. Welded joints will be fully painted after welding to prevent corrosion.
