Polyethylene Products Linear low-density polyethylene (LLDPE) is a thermoplastic used in a variety of products. It is a semi-permeable, pliable, and highly durable polymer that is favored in industry for its low cost and high resistance. Polyethylene is classified into categories based on density and chemical characteristics. Its mechanical properties depend on molecular weight, crystalline structure, and branching type. While properties vary by grade, it generally offers good resistance to outdoor conditions and moisture, flexibility, modest mechanical strength, and excellent chemical resistance. Polyethylene components are used in the manufacture of slides, stairs, handrails, barriers, accessories, roofing, and more. To prevent color fading, masterbatch pigments used for coloring polyethylene must have a light fastness rating of 6 or higher. Wall thickness: material exposed to pressure and friction must be at least 6 mm (0.2 in); products not subject to pressure, such as barriers and shade structures, require a minimum of 4 mm (0.2 in). Material must be evenly distributed to achieve uniform thickness. Wall thickness and dimensional tolerances are ±5 %. Carrier Construction The carrier frame consists of circular‑section steel tubes that are 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). Tubes are welded using high‑frequency welding and finished with a polyester‑based electrostatic powder coating applied in a furnace. Electrostatic Powder Coating All metal parts are first blasted to remove oil, dirt, and rust, creating a textured surface for optimal paint adhesion. A fine bead material is then sprayed with pressurized air to further open the surface and clean any remaining contaminants. After blasting, parts are coated with a polyester‑based electrostatic powder and cured in a 200‑220 °C oven for 20 minutes. Subsequently, the parts undergo a 10‑minute oil‑removal bath at 70 °C with a 5 % concentration, followed by a 15‑minute iron‑dip bath at 50 °C with a 1 % concentration, then rinsed and dried. Finally, the components receive a durable polyester powder coating applied outdoors and cured at 180‑200 °C for 20‑30 minutes. Welded joints are fully painted after welding to prevent corrosion.
