Hypalon Molded Parts

Rol‑Tec in Green Bay, Wisconsin, is a top provider of Hypalon rubber rollers and Hypalon rubber molded parts, delivering durable, high-performance solutions for the chemical processing, automotive, electronics, and manufacturing sectors. With nearly 35 years of experience, our end‑to‑end in‑house capabilities—from compound selection through precision machining and coating—ensure exceptional quality and reliable delivery.

What Is Hypalon?

Hypalon, a chlorosulfonated polyethylene (CSPE) compound originally introduced by DuPont in the 1950s, is prized for its resistance to corrosive chemicals, extreme temperatures, ozone, UV radiation, and solvents. It can be blended with silicone or PTFE to enhance release and safety in demanding environments.

Hypalon is identified under trade names like HY, HA, CSM, and CSPE. Its exceptional resistance to acids, caustics, water, and solvents makes it well-suited for roller and part applications in aggressive conditions.

Extend the lifespan of existing rollers with our roller re‑covering services using Hypalon compound. We inspect rollers, assess wear, and either perform precision “kiss-grinds” or strip and re‑cover cores with fresh Hypalon covers up to 31″ diameter and 280″ inches in length.

We also repair and rebore journals and bores, perform dynamic balancing, precision grinding, and reverse-engineering of unusable cores. Full in‑house control ensures fast turnaround and consistent, factory-quality results.

Rol‑Tec manages every aspect of the manufacturing process on-site, eliminating outsourcing and ensuring uniform quality across all stages :

• Compound selection for Hypalon blends with or without silicone/PTFE
• Mold design and fabrication for compression and transfer parts
• Rubber-to-metal bonding and core preparation
• CNC machining, turning, milling, grinding, and dynamic balancing
• Laser engraving for texturing and measurement profiling
• Plasma metalized coatings (tungsten carbide, ceramic)

Compression molding and precision post-mold machining

Our precision components serve demanding environments in chemical processing, automotive assembly, electronics production, and industrial manufacturing. Hypalon roller applications include:

• Acid and caustic-resistant conveyor and drive rollers
• Automotive paint line rollers exposed to solvents
• Semiconductor and electronics handling rollers requiring clean and release properties
• Manufacturing equipment rollers needing abrasion resistance and long life

Engineers depend on Rol‑Tec’s expertise in material selection, compound design, and production excellence to prevent downtime and deliver consistent performance.
