High Melt Flow Masterbatch

Updated: 2026-07-24

Overview

High Melt Index Polypropylene (HMIPP) is a specialized form of polypropylene characterized by its high melt flow rate (MFR), typically ranging from 20 to 100 g/10 min. This property makes it highly suitable for injection molding and other high-speed processing techniques. HMIPP is derived from propylene monomers and is known for its excellent balance of rigidity, chemical resistance, and processability. It is widely used in industries requiring rapid production cycles, such as packaging and automotive manufacturing.

Physical and Chemical Properties

HMIPP exhibits a density of 0.89-0.91 g/cm³ and a melting point range of 160-170°C. Its high melt flow rate ensures easy flow into molds, reducing cycle times and improving production efficiency. The material is insoluble in water but dissolves in organic solvents like xylene and chlorinated hydrocarbons. It is resistant to acids, alkalis, and most solvents, making it suitable for a wide range of applications.

Main Applications

HMIPP is predominantly used in the packaging industry for producing thin-walled containers, caps, and closures due to its high flow properties and rigidity. It is also employed in automotive parts like battery cases and interior trim components. In the consumer goods sector, HMIPP is used for making household items, toys, and disposable products. Its ability to be processed at high speeds makes it a cost-effective choice for mass production.

Safety and Storage

HMIPP is generally considered safe for handling, but precautions should be taken to avoid inhalation of dust during processing. Adequate ventilation is recommended to minimize exposure. The material should be stored in a cool, dry place away from direct sunlight to prevent degradation. Proper storage conditions ensure the material retains its properties over time.

B2B Procurement Guide

When procuring HMIPP, buyers should verify the melt flow rate (MFR) specifications to ensure compatibility with their processing equipment. It is also advisable to request material data sheets for detailed property information. Prices for HMIPP typically range from $1.20 to $1.50 per kg, depending on the supplier and quantity purchased. Bulk purchases may offer cost savings, but buyers should also consider logistics and storage costs.
