Product Description
Product Overview
First® FM-42 is a universal flow demoulding agent based on a synergistic blend of saturated fatty acid soap salts and high-efficiency lubricants. It is designed to solve two key challenges in rubber processing: poor flow and difficult demolding.
This internal processing aid reduces green rubber viscosity, enhances cavity filling, and ensures clean release from molds – especially in complex-shaped molds, microcellular foaming, and injection molding applications.
FM-42 is suitable for a wide range of general-purpose rubbers, including NR, SBR, BR, NBR, and EPDM.
Key Features & Benefits
Improves flowability – Significantly reduces compound viscosity, making rubber easier to process in extrusion, injection, and compression molding
Enhances demolding – Provides excellent internal release, reducing mold sticking and improving production efficiency
Increases injection shot volume – In injection molding, FM-42 allows higher shot volume per cycle, especially for complex or thin-wall molds
Improves dimensional stability – Helps maintain consistent part dimensions, reducing scrap rates
Enables better venting – Enhances air evacuation during molding, reducing defects like bubbles or incomplete fill
Acts as a dispersing agent – Improves dispersion of fillers, curatives, and other additives for more consistent compound quality
Suitable for microcellular foaming – Promotes uniform cell structure in foamed rubber products
Advantages Over Traditional Processing Aids
Lower melting point (60-70°C) ensures easy dispersion at typical rubber mixing temperatures
Balanced soap salt and lubricant system provides both flow promotion and release performance
No negative impact on cure kinetics when used within recommended dosage range
