Foam Swab Technical Specifications
Swab-its® foam swabs are precision cleaning and application tools designed for professional, industrial, electronic, printing, firearm, cleanroom, and manufacturing environments.
This technical specifications guide provides general information about foam materials, handle materials, swab construction, dimensions, solvent compatibility, packaging, and product selection.
Made in the USA Foam Swabs
Swab-its® foam swabs are Made in the USA by Super Brush LLC in Springfield, Massachusetts. With over 65 years of foam swab manufacturing experience, Super Brush produces precision foam swabs for cleaning, applying, spreading, absorbing, sampling, and surface preparation.
Swab-its® foam swabs are designed for superior lint-free performance compared to cotton swabs, paper wipes, and other disposable applicators.
General Swab Construction
| Component | Common Material | Purpose |
|---|---|---|
| Foam Head | Polyurethane foam | Used for lint-free cleaning, absorbing, applying, wiping, drying, and controlled fluid transfer. |
| Handle | Polypropylene plastic or birch wood | Provides reach, control, support, and application-specific handling. |
| Foam Tip Shape | Rectangular, circular, narrow, mini, large, or custom shapes | Allows the swab to match flat surfaces, grooves, tubes, bores, ports, slots, and hard-to-reach areas. |
| Swab Length | Varies by product | Short, medium, long, and extra-long handles support different cleaning and application needs. |
Foam Head Material
Most Swab-its® foam swab heads are made from polyurethane foam. Foam provides a soft, absorbent, non-abrasive cleaning surface that helps reduce loose fibers and lint compared to cotton swabs.
- Soft foam for delicate surfaces
- Lint-free cleaning performance
- High absorbency for fluids, oils, solvents, and cleaners
- Controlled release for applying lubricants, coatings, adhesives, and cleaning solutions
- Designed to clean without the loose cotton fibers associated with traditional cotton swabs
Handle Materials
Swab-its® foam swabs may use different handle materials depending on the product and application.
- Polypropylene handles: Durable plastic handles commonly used for precision cleaning, industrial cleaning, electronics, printing, firearms, and general-purpose applications.
- Birch wood handles: Used on select swab styles where a wood handle is preferred for the application.
- Flexible handles: Available on select designs for cleaning around curves, contours, and irregular surfaces.
- Extended handles: Available for deep-reach cleaning, machinery, tubes, bores, inspection areas, and maintenance tasks.
Common Foam Tip Shapes
| Tip Shape | Best For | Common Applications |
|---|---|---|
| Rectangular Foam Tips | Flat surfaces and controlled wiping | Printheads, rollers, machinery, surfaces, rails, and application work. |
| Narrow Rectangular Foam Tips | Tight spaces and detail cleaning | Slots, seams, grooves, edges, ports, sensors, slides, and rails. |
| Circular Foam Tips | Round surfaces and fluid application | Bores, tubes, openings, chambers, cavities, and controlled solvent application. |
| Mini Foam Tips | Small parts and delicate areas | Electronics, keyboards, connectors, sensors, optics, and small components. |
| Extra-Long Foam Swabs | Deep-reach cleaning | Industrial maintenance, machinery, CMM cleaning, tubes, and hard-to-access surfaces. |
