2. Core Product Advantages
High melt flow improves injection molding efficiency
This resin has excellent melt fluidity and fast mold filling speed. It shortens production molding cycle and improves overall output efficiency. It keeps stable melt flow during processing, effectively avoiding common defects such as short shots, sink marks and bubbles. With smooth product surface, it fits small and medium precision injection parts with complex structures, matching most mainstream injection molding equipment.
Balanced rigidity and toughness for stable mechanical performance
This material is designed with high rigidity while retaining practical toughness. Finished products have strong deformation resistance, load-bearing capacity and compression resistance. It fully meets high strength requirements of turnover boxes and rigid containers, and reduces product breakage risks during storage, transportation and daily use.
Good chemical resistance for diverse application scenarios
It has stable resistance to acid, alkali, salt and common organic solvents. It will not crack, whiten or degrade after long-term contact with daily chemical products. It is suitable for civil daily packaging and ordinary industrial plastic containers.
Great environmental stress cracking resistance to extend service life
The material can resist cracking caused by repeated external stress and temperature changes. It runs stably for long-term indoor use and mild outdoor exposure, greatly prolonging the service life of finished plastic products.
Pure base formula with flexible modification space
This HDPE resin adopts pure base material formula without extra restrictive additives. Manufacturers can freely add color masterbatch, UV stabilizer, impact modifier and other functional additives to adjust product performance according to actual production demands.
3. Main Application Fields
Packaging Accessories: Various plastic caps including detergent caps and cosmetic caps, sealing covers, small packaging containers and bucket covers. It features precise molding size, tight thread matching and good sealing performance.
Logistics Turnover Products: Plastic turnover boxes, cargo crates and small storage bins. Its high rigidity and compression resistance adapt to repeated turnover use in warehouse and logistics industries.
Daily Plastic Products: Household plastic tableware, toiletry containers and daily plastic fittings. The material is odorless and safe for daily household use.
Toys and Light Industrial Products: Plastic toys, small injection crafts and general light industrial plastic parts. It contains no harmful ingredients and meets common toy safety standards.
Industrial Containers: Small chemical distribution tanks and conventional liquid storage containers. Its stable corrosion resistance fits simple chemical packaging scenarios.
This resin can be blended with other HDPE materials to adjust melt fluidity and product rigidity flexibly for different production processes.
4. Injection Molding Processing Guidelines
Recommended Process Parameters
Barrel temperature: 180–220°C, heat gradually from feed inlet to nozzle.
Nozzle temperature: 190–220°C, which shall not be higher than the rear barrel temperature.
Mold temperature: 20–60°C. Use lower temperature for thin-wall parts and higher temperature for thick-wall parts to ensure stable product size and smooth surface.
Injection pressure: Medium pressure, adjust properly according to product size and wall thickness.
Drying requirement: No drying needed for normally stored pellets. Dry damp pellets at 60–70°C for 1 hour before production.
Blending suggestion: Mix Shenhua 8007 with common HDPE at 80:20 ratio to balance melt flow and product rigidity, and control production cost reasonably.

6. Frequently Asked Questions
Q1: Will short shot defects appear when producing thin-wall small parts?
A: No short shot will occur. This resin has excellent melt flow and uniform mold filling performance. It is very suitable for thin-wall and complex-shaped parts, and effectively reduces defects such as sink marks and weld lines.
Q2: What are the core advantages of Shenhua 8007 for plastic cap production?
A: It supports faster molding cycle to improve production efficiency. Its high rigidity prevents finished caps from deformation. Besides, it has good chemical resistance against daily chemicals and cosmetic raw materials, which is perfect for mass production of plastic caps.
Q3: How to improve product hardness if finished products are too soft?
A: Blend Shenhua 8007 with high-rigidity HDPE at 80:20 ratio to increase overall product hardness. Add a small amount of impact modifier if higher toughness is required.
Q4: What problems will damp pellets cause, and how to handle it?
A: Damp pellets will lead to bubbles and watermarks on product surface, damaging appearance and mechanical strength. Dry wet pellets at 60–70°C for 1 hour and cool to room temperature before injection processing.
Q5: Can this resin be used for food-contact plastic products?
A: It can be used for indirect food outer packaging. Please complete relevant compliance tests and follow local industry standards if used for direct food contact scenarios.
