Fochem International’s ISOLAT 70 G and ISOLAT 80 G are high-purity, synthetic wax-based plunger lubricants for aluminium die casting. Supplied as round, free-flowing, anti-static, and dust-free beads, ISOLAT 70 G contains 10% graphite, while ISOLAT 80 G has 20%, enhancing lubrication to reduce friction between the plunger and shot sleeve. This extends plunger life and minimizes die build-up for efficient, high-quality casting. During the process, the beads melt, rapidly forming a protective layer on steel surfaces via capillary action, reducing aluminium adhesion and erosion. Free from toxic substances like aromatic compounds, both products are low-odour and eco-friendly, meeting industry sustainability demands. Available in three particle sizes (0.5–1.0 mm, 1.0–1.6 mm, 1.6–2.0 mm), they offer application flexibility. ISOLAT 70 G and ISOLAT 80 G reduce maintenance costs and enhance casting precision, making them ideal for automotive and aerospace industries. Fochem’s innovative solutions ensure superior performance in the global die casting market.
ISOLAT 70 G is a high-purity, synthetic wax-based plunger lubricant for the aluminium die casting industry.
The product is supplied in bead form, which is round, free-flowing, anti-static, and dust-free. It contains approximately 10% graphite to enhance lubrication performance.
During the casting process, the beads melt inside the shot sleeve and distribute rapidly via capillary action. This forms a uniform protective layer on steel surfaces, reducing aluminium adhesion and erosion. The lubricant also effectively reduces friction between the plunger and shot sleeve, contributing to extended plunger life and minimized die build-up.
ISOLAT 70 G is free from toxic substances such as aromatic compounds, making it a low-odour and environmentally responsible alternative to conventional plunger lubricants.
The product is available in the following particle size ranges:
These size options allow for application flexibility depending on process requirements.

ISOLAT 208 SP is a high-viscosity, oil-based graphite lubricant.
It is used in drip lubrication systems. Suitable for aluminium die casting as well as other high-temperature applications, such as lubrication of aluminium extrusion rams, shears, and die faces.
The lubricant forms a thin, resilient film on contact surfaces, which helps protect the shot sleeve against melt erosion. Significantly reducing adhesion-related wear. Its formulation ensures reliable performance in high-stress environments, contributing to extended service life of both plungers and sleeves.
ISOLAT 218 PL is a viscous, oil-based, graphite-free plunger lubricant.
It contains inorganic thickening agents ensuring exceptional adherence.
The thin, tacky consistency forms a durable lubricating film that resists wear and prevents surface erosion across a wide temperature range.
ISOLAT 218 PL is created for plunger systems in high-stress conditions, it offers reliable protection and smooth operations. Ultimately extending equipment life in aluminum die casting and similar applications.
DISREX HC is a wax-free, water-in-oil release agent formulated as a stable dispersion for high-pressure die casting.
Developed for thin-walled and large structural components made from aluminum and magnesium. DISREX HC offers superb release performance with added lubrication for ejector pins, resulting in smooth surfaces and reduced metallization.
Its stable formulation eliminates the need for stirring, prevents residue build-up, and keeps spray systems and mould frames clean.
DISPREX HC delivers clean, residue-free surfaces compatible with painting, powder coating, and welding.
DISPREX GF is a wax-free, water-in-oil release agent made from biodegradable oil. Developed for high-pressure die casting of aluminum and magnesium components.
It forms a stable, water-repellent film that adheres directly to the die surface, resisting displacement during spraying. Suitable for complex, large, and heavy castings,
DISPREX GF delivers clean, residue-free surfaces compatible with painting, powder coating, and welding. Its formulation also enhances cooling, reduces gas entrapment, and supports shorter cycle times, improving both efficiency and casting quality.
ISOLAT UP 27 is an oil-based, graphite-free release agent.
Engineered for high-demand applications in die casting.
Aimed at supporting start-up operations and coating of new dies. Providing intermittent release for complex or specific castings.
Its non-water-based formulation ensures superior release performance, even under challenging conditions.
A concentrated version is also available, making it suitable for export and compliant with international transport regulations.
ISOLAT ZN 90 is an oil-based, graphite-free release agent for zinc pressure die casting.
