SIBUR 85612 | Injection Molding HDPE, High Rigidity & Low-Temperature Toughness for Turnover Boxes
Product Overview
SIBUR 85612 is injection-grade HDPE produced by Russia SIBUR ZapSibNeftekhim via low-pressure slurry polymerization process. This resin features balanced melt fluidity, high flexural rigidity and stable low-temperature notch impact resistance. Finished injection parts deliver smooth high-gloss surface, and the virgin raw material complies with global food contact safety standards.
Supported by steady import supply from Russia and outstanding cost performance, it acts as a cost-effective imported raw material for mass production of logistics turnover containers, plastic pallets and thick-wall injection storage products.

2. Core Product Advantages
High rigidity & high surface gloss for premium part appearance
Manufactured via mature low-pressure slurry polymerization, this HDPE delivers outstanding rigidity and excellent surface gloss. Finished injection products feature smooth surface with minimal flow marks and weld lines. Secondary polishing procedures can be omitted, fully meeting production requirements of high-appearance plastic turnover goods.
Balanced wide-temperature toughness, strong anti-brittle cracking performance
It maintains stable impact resistance under both room and low-temperature environments, effectively preventing cold brittle fracture during repeated stacking, turnover and transportation. It greatly cuts product scrap rate and fits long-cycle heavy-duty cyclic usage scenarios.
Excellent melt fluidity matching high-speed injection production
Its well-balanced melt flow realizes fast, uniform mold filling for large-size and thin-wall injection components. Compatible with conventional and fully automatic high-speed injection molding machines, it stabilizes continuous production operation and improves overall finished product yield.
Stable imported supply & comprehensive chemical resistance
As mainstream imported injection HDPE from Russian SIBUR ZapSibNeftekhim, it avoids long delivery cycles and supply fluctuation risks of overseas raw materials. The low-odor virgin resin meets international food contact standards and holds reliable tolerance to weak acid & alkali corrosion for diversified injection molding applications.
3. Main Application Fields
Food Logistics Turnover Products: Beer turnover crates, beverage circulation boxes, food storage baskets, fresh cold-chain logistics containers
Industrial Heavy-Duty Injection Goods: Plastic logistics pallets, industrial spare parts turnover baskets, warehouse heavy-duty storage containers
Daily & Protective Plastic Products: Safety helmets, plastic tables & chairs, household thick-wall storage boxes, general daily injection molded parts
Other Applications: Modified plastic base resin; can be blended with small proportion LDPE to adjust finished product flexibility and impact toughness
4. Processing & Storage Guidelines
Processing Parameters
Barrel Temperature: 190–230°C
Mold Temperature: 40–60°C
Injection Holding Pressure: 60–110 MPa
Drying Requirement: No pre-drying treatment needed for normally stored pellets. Bake damp pellets at 60–70°C for 1 hour and fully cool to room temperature before feeding to injection machine.
Storage Requirements
Store resin pellets in cool, dry and well-ventilated warehouses. Keep away from open flames, rainwater, direct sunlight and strong-odor goods to avoid moisture absorption and odor cross-contamination. Do not stack pallets higher than 5 layers. Standard shelf life: 2 years under sealed dry storage conditions.
5. Quality Assurance & Supply Service
All supplied pellets are 100% genuine virgin SIBUR 85612 HDPE imported directly from ZapSibNeftekhim Russia factory. Original batch COA documents are provided for full-item laboratory inspection. We maintain sufficient year-round imported spot inventory, supporting small trial orders and full-truck / full-container bulk shipments. Professional one-stop injection parameter guidance and production troubleshooting technical support are available to meet diversified procurement demands of injection manufacturers.
6. Frequently Asked Questions
Q1: Will this high-flow HDPE cause sink marks and shrinkage depressions on large injection turnover boxes?A: Reasonable adjustment of holding pressure and cooling time can greatly suppress such defects. This grade features stable molding shrinkage rate; matched standard processing parameters effectively control surface sink marks and dimensional deviation.
Q2: How about its low-temperature impact performance? Is it suitable for cold northern outdoor turnover containers?A: It only has slight toughness loss under low-temperature environments and resists brittle fracture under subzero conditions, making it ideal for cold-chain logistics turnover boxes and warehouse containers used in frigid northern regions.
Q3: Can SIBUR 85612 be used for direct injection without blending other PE materials?A: It can be independently molded with stable injection processing performance. Optional blending of a small proportion of LDPE can further boost finished product flexibility and anti-cracking performance.
Q4: Can this HDPE be directly applied to food-contact turnover boxes?A: The base resin and internal stabilizer system comply with global food contact material standards, applicable for food-grade turnover baskets and storage containers. Users shall verify local regional compliance specifications according to final end-use products.
Q5: Will melt flow and rigidity drop obviously after long-term warehouse storage?A: All core physical indicators remain stable within the 2-year shelf life under standard sealed dry storage conditions. No obvious attenuation occurs on melt fluidity, rigidity and impact strength, with excellent batch-to-batch consistency.
