Daqing 5000S HDPE Wire Drawing Resin Selection Guide | High-Rigidity, Low-Temp Resistant HDPE Properties & Tips

Stable virgin HDPE is vital for heavy-duty flat yarn, woven bags and hollow container manufacturers. Many buyers pick cheap substitutes to cut costs but face growing production losses. Degraded recycled HDPE weakens yarn tensile strength, causing sacks to break under load. Impurities lead to melt fracture and frequent wire breaks at high drawing speeds, lowering output.

Such recycled resin turns brittle in cold climates, cracking fishing nets and outdoor ropes in northern winters. Poor acid, alkali and weather resistance makes goods fail export tests. When selecting HDPE, prioritize drawing stability, balanced toughness, rigidity, wear resistance, batch consistency and steady supply. Cost-effective domestic wire-drawing grade Daqing 5000S HDPE fits small trials and full-scale mass production. What advantages does it hold over low-cost generic HDPE? Key benefits are outlined below.

Most processors wrongly assume ordinary HDPE performs equally, and recycled pellets can replace virgin wire-drawing material. Cheap blended recycled HDPE has broad molecular weight distribution and unstable melt viscosity, triggering constant wire breaks and slower extrusion. High thermal shrinkage makes yarn curl in storage or outdoors, with inferior wear and anti-aging performance only for disposable simple packaging.

Made via Daqing Petrochemical gas-phase fluidized bed polymerization, Daqing 5000S HDPE features narrow molecular weight distribution and uniform chains for smooth extrusion torque. It runs stably at 180–210°C and avoids sharkskin defects and wire breaks in high-speed drawing. Its yarn hits ≥30 MPa tensile strength and ≥500% elongation at break with balanced rigidity and toughness. The resin stays tough below -80°C. Pure contaminant-free pellets ensure even pigment dispersion and consistent product look. With strong chemical & stress crack resistance and food-contact compliance, it reliably replaces imported wire-drawing HDPE.

Below are key parameters of Daqing 5000S for quick reference by purchasers and technical staff:

This plastic fits many production ways: wire drawing, injection molding, and blow molding.

· Factories making woven bags and strapping tape get yarn with strong breaking force, steady load capacity, and small thermal shrinkage.

· Aquaculture factories make fishing nets and ropes. The material stands low temperature, wear, and seawater corrosion. Goods do not age or crack fast under long outdoor use.

· Daily chemical and chemical packing factories make 5–20 L hollow barrels and turnover boxes. The plastic has enough hardness and resists cracking under pressure. Goods do not deform when stacked.

· Factories can mix a small amount of LLDPE with this HDPE. It balances product toughness and cuts raw material cost.

Key Purchasing Tips

Do not only look for a low single price. Machine stop loss, broken defective yarn, and customer return cost far more than the price gap of raw materials. Do not judge plastic only by tensile strength. Low-temperature toughness, fixed melt index in every batch, and stable supply chain are equally necessary.No need to buy imported HDPE blindly. Daqing 5000S HDPE works with most domestic extrusion and injection machines. It costs less and the delivery time is clear.

Raw material selection should put quality and safety first. Choose plastic matching your real use environment. It reduces the money spent on machine testing and after-sales complaints.
