High Flow High Rigidity Injection Molding HDPE | Zhejiang Petrochemical T60-800 for Bottle Caps & Thin-Wall Containers
Product Overview
Zhejiang Petrochemical T60-800 is virgin injection-grade HDPE resin produced via low-pressure gas-phase polymerization. As mainstream high-flow rigid HDPE, it features narrow molecular weight distribution and balanced melt fluidity & mechanical rigidity, perfectly matching mass production of thin-wall injection molded parts.
It delivers outstanding resistance to weak acids, alkalis and daily organic solvents, maintaining stable dimensional stability under long-term assembly load. The virgin formula complies with global food contact safety standards with low additive precipitation, suitable for food-grade caps and thin food containers. Supported by Zhejiang Petrochemical’s large-scale stable domestic production line, it has prominent cost performance and serves as the preferred domestic HDPE grade for daily plastic injection manufacturers.

Core Product Advantages
Excellent High Melt Flow for Thin-Wall High-Speed Injection
The 8.5 MFR delivers smooth melt flow to fill complex thin-wall mold cavities without short shot, shortening injection cycle and lifting production efficiency. Uniform molecular weight distribution reduces internal stress and product warpage after demolding, supporting stable mass production of ultra-thin bottle caps and shallow containers.
Balanced High Rigidity & Moderate Impact Toughness
High flexural modulus provides strong structural stiffness to prevent permanent deformation under stacking and assembly pressure. Moderate room-temperature notch impact strength avoids cracking during falling and transportation, balancing rigid appearance and durable service life for daily plastic goods.
Good Chemical Resistance & Stable Glossy Surface
It resists erosion from daily weak acid, alkali and cosmetic chemical liquids, keeping intact surface and mechanical performance for long-term storage. Molded parts present uniform high-gloss finish without sink marks, reducing secondary polishing and simplifying post-processing.
Low Extraction Virgin Formula, Wide Blending Compatibility
No harmful additives in the polymerization formula, meeting food contact test standards for caps and food containers. Users can blend with small proportion LLDPE to adjust product flexibility as required, compatible with common plastic modifiers for customized product performance.
Main Application Fields
Food & Cosmetic Packaging
Drink plastic bottle caps, daily chemical lotion caps, thin-wall food storage containers, disposable plastic food lids
Daily Household Plastic Goods
Plastic storage baskets, turnover crates, laundry plastic boxes, children plastic toy shells
General Industrial Injection Parts
Small electrical equipment outer housings, lightweight plastic structural brackets, logistics plastic pallet accessories
Processing & Storage Guidelines
Processing Parameters
Recommended injection barrel temperature range: 200–230°CMold temperature: 40–60°CReminder: Avoid temperature exceeding 240°C to prevent thermal degradation of HDPE melt.
Drying Guidance: No pre-drying required under normal warehouse storage. If pellets absorb excessive moisture from damp environment, bake at 60–70°C for 1 hour and fully cool to room temperature before feeding to injection machine.
Storage Requirements
Store pellets in cool, dry and well-ventilated warehouses. Isolate from open flames, rainwater, direct sunlight and strong-odor goods to avoid moisture absorption and odor cross-contamination. Max stacking layers per pallet: 5 layers. Standard shelf life: 2 years under sealed dry storage conditions.

Frequently Asked Questions
Q1: What advantages does Zhejiang Petrochemical T60-800 have over imported HDPE injection grades?A1: Domestic spot stock realizes fast delivery without ocean freight and tariff cost, bringing better cost performance. Its batch stability and thin-wall molding performance are equivalent to imported mainstream HDPE caps grades, with stable consistent performance for continuous mass production.
Q2: Is this HDPE grade suitable for long-term outdoor exposure products?A2: It owns basic weather resistance for short-term indoor use only. For products requiring long-term outdoor service, anti-UV masterbatch blending is necessary to slow yellowing and aging.
Q3: Does T60-800 comply with food contact safety standards?A3: Adopting low-migration virgin polymerization formula without toxic additives, it passes domestic and international food contact material regulations, applicable for food bottle caps and short-term food thin containers. Complete compliance certificates can be supplied for batch inspection.
Q4: Can T60-800 be blended with other PE resins?A4: Pure T60-800 achieves maximum rigidity and gloss. If softer, less brittle finished parts are needed, blend with 10–20% LLDPE to balance stiffness and impact resistance.
Q5: What technical support and delivery cycle can you provide?A5: Sufficient spot stock in East China warehouses ensures fast delivery. Our technicians provide recommended injection molding parameters and solve common defects such as product warpage, flow marks and insufficient filling.
