Overview
PE55F40 is a grade of high-density polyethylene (HDPE) engineered for superior mechanical performance and resistance to chemicals and environmental stress. It is widely utilized in industries requiring durable, lightweight materials, such as construction, packaging, and agriculture. Its molecular structure provides high tensile strength and flexibility, making it ideal for applications like pressure pipes and industrial liners. The material is also recyclable, aligning with sustainability goals in modern manufacturing.
Physical and Chemical Properties
PE55F40 exhibits a density of around 0.95 g/cm³, contributing to its robustness while remaining lightweight. Its melting point ranges between 130–135°C, ensuring stability under moderate thermal conditions. The polymer is insoluble in water and resistant to acids, alkalis, and organic solvents, making it suitable for chemical storage and transport. Its UV-stabilized variants are often used in outdoor applications to prevent degradation from sunlight exposure.
Main Applications
In the construction sector, PE55F40 is a preferred material for piping systems due to its leak-proof joints and corrosion resistance. It is also used in geomembranes for landfill liners and water containment. Industrial packaging, such as drums and intermediate bulk containers (IBCs), leverages its chemical inertness. Additionally, it serves in automotive components and agricultural films, where durability and weather resistance are critical.
Safety and Storage
PE55F40 is non-toxic and compliant with FDA standards for food-contact applications. However, processing at high temperatures may release fumes, requiring adequate ventilation. Storage recommendations include keeping the material in sealed bags or containers to prevent moisture absorption. Avoid prolonged exposure to temperatures above 50°C to maintain its properties.
B2B Procurement Guide
When sourcing PE55F40, prioritize suppliers with ISO 9001 certification to ensure quality consistency. Request technical datasheets detailing melt flow index (MFI) and tensile strength for compatibility with your project. Bulk purchases typically offer cost savings, with prices fluctuating based on crude oil markets. Confirm lead times and logistics options, especially for international shipments, to avoid production delays.
