PIBSA Components for Superior Metalworking Performance
Metalworking has evolved, but many of the emulsifiers used in metalworking fluids haven’t. For decades, formulators have relied on legacy chemistries originally developed for other applications. These adapted emulsifiers often introduce challenges: unstable emulsions, excessive foam, shorter fluid life, and unnecessary formulation compromises.
Nelson Brothers’ PIBSAs change that.
Our PIBSAs for metalworking fluids are made to emulsify, giving formulators a stronger foundation for cleaner blends, longer stability, and reliable performance under demanding conditions.
Made to Emulsify – Why Your PIBSA Choice Matters
Metalworking fluids depend on consistent emulsification to deliver cooling, lubricity, and surface protection. When emulsifier components aren’t designed for this role, your fluid’s performance suffers. PIBSA from Nelson Brothers has been designed for emulsification from the start. All our PIBSA products are batch-made and free of chlorides and poly-maleic tars.
Nelson Brothers PIBSAs provide:
- Superior emulsion stability in hard-water environments
- Minimal foam formation under circulation, shear, and real-world use
- Cleaner, faster bloom for efficient blending
- Longer fluid life and improved reliability
- Outstanding bio-resistance for better workplace hygeine
- Consistent performance across soluble oils and semi-synthetics
Our PIBSAs are engineered specifically for emulsification, giving you performance that sulfonates and fatty acid derivatives simply can’t match.
How to Overcome Metalworking Friction
Metalworking fluids play a critical role in managing heat, friction, and wear during machining and forming operations. To do this effectively, the fluid must maintain a stable emulsion that delivers consistent lubrication and cooling at the tool–workpiece interface.
A well-formulated metalworking fluid helps:
- Reduce friction and heat buildup
- Improve lubrication under high shear
- Protect tooling and workpiece surfaces
- Extend tool and equipment life
- Maintain cleanliness and prevent deposits
- Support smoother cutting and higher productivity
These benefits depend on one thing: a stable emulsion.
And a stable emulsion starts with an emulsifier designed for the demands of metalworking.
When your emulsifier is made to emulsify, rather than adapted into the role, you get cleaner blends, consistent lubrication, and performance that holds up in real-world conditions.
Why Metalworking Lubrication Matters
Metalworking is a process that creates parts, assemblies, and structures from raw materials using hard tooling. Operations such as milling, turning, grinding, stamping, and forming generate intense friction and heat at the cutting zone. Without proper lubrication:
- Tools wear prematurely
- Workpieces score, warp, crack, or burn
- Heat builds faster than it can dissipate
- Surface finish degrades
- Scrap and rework increase
- Energy consumption rises
Lubrication isn’t optional.
It’s essential to protect tools, preserve part quality, and maintain process efficiency.
Metalworking fluids rely on stable emulsification to deliver that lubrication. If the emulsifier isn’t designed for the job, the fluid breaks down, leading to foam, instability, poor cooling, and costly downtime.
Custom Emulsifiers for Your Metalworking Formulations
Your customers, processes, and performance targets aren’t generic. Your emulsifier shouldn’t be either.
Nelson Brothers offers:
- PIBSA core components for common metalworking formulations
- Custom PIBSA blends diluted with paraffinic or naphthenic oils
- Neutralized PIBSA solutions (KOH, alcohol, glycol, or amine) for added functionality
- Collaborative product development to match your performance requirements
Our technical and process engineering teams partner with you to create an emulsifier that helps you achieve your formulation goals.
