Polyethylene Products Linear low‑density polyethylene (LLDPE) is a thermoplastic used in a variety of applications. It is a semi‑permeable, easily softened, and highly durable polymer. Its low cost and high resistance make it a favorite in industry. Polyethylene is classified into different categories based on density and chemical properties. Mechanical properties depend on molecular weight, crystal structure, and branching type. While properties vary by grade, common attributes include good resistance to outdoor conditions and moisture, flexibility, low mechanical strength, and excellent chemical resistance. Polyethylene components are used to manufacture slides, stairs, railings, barriers, accessories, roofs, etc. To prevent colour fading, masterbatch pigments used for colouring polyethylene must have a light‑fastness value of 6 or higher. Part thickness: areas exposed to pressure and friction must have a minimum thickness of 6 mm (0.2 in); products not exposed to pressure—such as barriers and shading elements—must be at least 4 mm (0.2 in) thick. Material distribution must be uniform, providing consistent thickness. Thickness tolerance is ±5%. Carrier Construction Steel tubes with a minimum outside diameter of 114 mm (4.5 in) and a wall thickness of at least 2 mm (0.1 in), conforming to TS EN 10219‑2, TS‑6476, DIN 2394, are cold‑formed and welded by high‑frequency welding. Tubes are produced within the standard tolerance ranges for dimensions and cross‑section. The carrier assembly is sandblasted and then coated with a polyester‑based electrostatic powder finish. Electrostatic Powder Coating Process All metal parts are first cleaned by sandblasting to remove oil, dirt, and rust, creating a porous surface for better paint adhesion. A fine‑ball powder is then sprayed with compressed air to open pores and remove contaminants. After coating with the polyester‑based electrostatic powder, the parts are baked at 200‑220 °C for 20 minutes. Subsequent finishing includes a 10‑minute dip in a 70 °C, 5 % concentration degreasing bath, followed by a 15‑minute dip in a 50 °C, 1 % iron‑phosphate bath. After rinsing and drying, the components receive a final polyester‑based powder coating for outdoor durability, cured in a 180‑200 °C furnace for 20‑30 minutes. All welds are fully painted after welding to prevent corrosion.
