Impact of Decreased MFI on Material Properties A decrease in MFI typically indicates an increase in the polymer's molecular weight, resulting in higher viscosity. This change can enhance several properties of the material: Increased Hardness: Lower MFI polymers have higher molecular weight, leading to a denser and more rigid structure, which increases hardness. Increased Toughness: Higher molecular weight polymers exhibit better toughness, meaning they can absorb more energy before breaking. …

  Understanding Melt Flow Index (MFI) in Polymers The Melt Flow Index (MFI), also known as Melt Flow Rate (MFR), is a crucial parameter in the polymer industry. It measures the ease of flow of a thermoplastic polymer melt under specified conditions of temperature and pressure. Essentially, MFI provides an indication of the polymer's viscosity and molecular weight, which are critical factors in determining its processing and end-use properties.   …

    Polyethylene (PE) is one of the most widely used thermoplastic polymers in the world. It is produced through the polymerization of ethylene gas and is known for its versatility, durability, and cost-effectiveness. Polyethylene is a linear polymer composed of repeating units of ethylene (C₂H₄), making it one of the simplest and most common types of plastic    Types of Polyethylene Polyethylene comes in several different grades, each with …
