Product Overview
SECCO HD5502FA is a high-density polyethylene (HDPE) resin manufactured by Shanghai SECCO Petrochemical Company Limited. This product is a blow molding grade resin characterized by a high molecular weight distribution, which provides balanced rigidity and environmental stress crack resistance (ESCR). It is specifically engineered to ensure high parison strength and uniform wall thickness distribution in large-volume hollow container production. This grade is primarily intended for use in extrusion blow molding processes for the manufacturing of medium-to-large industrial containers.

Logistics & Supply Standards
To ensure supply chain reliability, SECCO HD5502FA is supplied in standard industrial packaging, typically 25kg multi-wall paper bags or heavy-duty plastic woven bags. We maintain consistent inventory levels in our primary distribution centers to support ongoing demand. The lead time for shipment is typically 7–14 business days, subject to the final terms of the sales contract and destination requirements. As this product is classified as a non-hazardous, non-powdered granular material, it is suitable for consolidated transport with other compatible non-restricted plastic raw materials, provided that all safety and compatibility guidelines are strictly followed.
Compliance & Quality Commitment
We provide comprehensive technical documentation support to ensure full product transparency, including original TDS (Technical Data Sheet), MSDS (Material Safety Data Sheet), and COA (Certificate of Analysis) for every batch. The product is manufactured under strict quality management systems and complies with international regulations, including REACH and RoHS standards. We maintain a robust batch-traceability system, allowing for the verification of material provenance and quality data from the point of production to final delivery.
Sustainability & ESG
As a thermoplastic material, SECCO HD5502FA is fully recyclable and supports circular economy initiatives when processed through appropriate recovery streams. During extrusion, this resin exhibits low volatility, contributing to reduced VOC emissions in the manufacturing environment. The material does not contain intentionally added heavy metals or halogens. We adhere to green supply chain requirements and assist our clients in optimizing waste management protocols to minimize environmental impact throughout the product lifecycle.
Frequently Asked Questions (FAQs)
Q1: Does HD5502FA require pre-drying before extrusion blow molding?
A: While HDPE is generally less hygroscopic than engineering resins, surface moisture may accumulate during storage in humid environments. To ensure optimal melt homogeneity and prevent surface defects, it is recommended to dry the resin at 80°C for 2–3 hours if moisture exposure is suspected.
Q2: If the application involves containing chemicals, how is the chemical resistance performance of this grade?
A: SECCO HD5502FA exhibits good chemical resistance and is suitable for containers of various industrial cleaners and acid/alkali solutions. However, due to the wide variety of chemicals, compatibility is influenced by concentration, storage temperature, and duration. It is recommended that customers conduct compatibility tests for specific fillers before formal mass production or refer to our chemical resistance guidance document.
Q3: How does HD5502FA compare to other HDPE grades for industrial container manufacturing?
A: HD5502FA is optimized for blow molding, specifically balancing processability (flow) with end-product toughness (ESCR). Compared to high-flow injection molding grades, it offers significantly higher parison stability; compared to ultra-high-molecular-weight grades, it offers superior process efficiency. Selection should be based on the specific container volume, geometry, and expected chemical exposure requirements of the end-use application.
