Polyethylene Products Linear low‑density polyethylene (LLDPE) is a thermoplastic used in various products. It is a semi‑permeable, pliable, and highly durable polymer that is popular in industry due to its low cost and high resistance. Polyethylene is classified into categories based on density and chemical properties. Mechanical properties depend on molecular weight, crystalline structure, and branching type. While properties vary by type, general characteristics include good resistance to outdoor conditions and moisture, flexibility, low mechanical strength, and excellent chemical resistance. Polyethylene products are used to manufacture slide, stairs, railings, barriers, accessories, roofs, etc. To prevent color fading, masterbatch dyes used for coloring polyethylene must have a lightfastness rating of 6 or higher. Wall thickness: For parts subject to pressure and friction, a minimum of 6 mm (0.2 in); for barriers and shading components not subjected to pressure, a minimum of 4 mm (0.2 in). Material must be evenly distributed to achieve uniform thickness. Wall thickness and dimensional tolerance are ±5 %. Carrier Construction The carrier construction consists of steel tubes with a circular cross‑section, cold‑formed to TS EN 10219‑2, TS‑6476, DIN 2394 standards with a minimum outer diameter of 114 mm (4.5 in) and a minimum wall thickness of 2 mm (0.1 in). After sandblasting, the tubes are painted with a polyester‑based electrostatic powder coating. Electrostatic Powder Coating All metal components are first sandblasted to remove oil, dirt, and rust, creating a porous surface for better paint adhesion. Fine metal beads are then blown with pressurized air to open pores and clean the metal surface. After manufacturing, the components are coated with a polyester‑based electrostatic paint and cured in a 200–220 °C oven for 20 minutes. Subsequent treatment includes a 10‑minute dip in a 70 °C, 5 % concentration degreasing bath, followed by a 15‑minute dip in a 50 °C, 1 % concentration iron bath. After rinsing and drying, the material is finally coated with a durable polyester powder paint in an outdoor electrostatic system and baked at 180–200 °C for 20–30 minutes. All welds are fully painted after welding to prevent corrosion.
