Vulkollan – The High-Performance NDI-based Polyurethane for Tough Industrial Jobs

2025-10-16

Why It Outperforms Standard Urethane in Wear, Load, and Harsh Conditions

When industrial applications demand elastomers that can handle constant friction, high speed, heavy loads, and harsh environments, standard MDI or TDI-based polyurethane often falls. That’s where Vulkollan NDI-based polyurethane stands out. As a specialized China manufacturer of custom polyurethane products, we’ve seen how Vulkollan’s unique NDI (naphthalene diisocyanate) chemistry solves pain points that plague standard elastomers, including rapid wear in high-friction setups to failure under repeated heavy loads.

I. Unmatched Abrasion Resistance – Lasts 5–8x Longer Than Rubber

The rigid naphthalene ring in Vulkollan’s molecular structure creates a dense, tough surface that resists scraping, grinding, and impact damage. Unlike standard polyurethane (which wears thin in 3–6 months in high-friction jobs), Vulkollan maintains its shape and performance for years.

Real Application: A South African mining company struggled with conveyor belt rollers that needed replacement every 4 months—standard rubber rollers couldn’t handle coal dust and constant contact. We supplied custom Vulkollan rollers: after 2 years, the rollers still showed minimal wear, cutting replacement costs by 75%.

Another example: A Vietnamese coal mine used standard polyurethane monorail wheels for their ore lifts. The wheels wore thin every month, forcing costly shutdowns to replace them. We supplied custom Vulkollan monorail wheels (93A hardness, precision-machined to match their track width). After 6 months, the wheels still had less than 1mm of wear—eliminating 5+ annual replacements and saving the mine over $12,000 in maintenance costs.

II. Superior Dynamic Load Capacity – Handles Repeated Impact Without Fatigue

Industrial machinery (like vibrating screen, presses, or printing equipment) subjects elastomers to constant “flex and impact” cycles. Standard polyurethane often develops cracks or deforms under this stress, but Vulkollan’s NDI structure absorbs energy efficiently, resisting fatigue even under daily dynamic loads.

Real Application: A German construction equipment maker needed buffer blocks for their concrete vibrators. Standard urethane blocks cracked after 8 weeks of vibration (1,500 RPM). Our Vulkollan buffer blocks lasted 18 months, with no signs of fatigue—letting the vibrators run longer between maintenance checks.

For a Japanese printing press manufacturer, Vulkollan rollers proved game-changing. The rollers handle 10,000+ sheets per hour, maintaining consistent pressure without warping while standard rollers needed re-calibration every month.

III.  Broad Chemical & Weather Resistance – in Harsh Environments

Industrial jobs often face oils, greases, solvents, or outdoor elements (UV, rain, extreme temps). Vulkollan holds up where standard urethane breaks down: it resists mineral oils, hydraulic fluids, and mild acids, plus retains performance from -40°C to 160°C.

Real Application: A Brazilian agricultural equipment company needed seals for their tractor hydraulic systems. Standard urethane seals swelled and leaked after 3 months of exposure to diesel and farm oils. We made custom Vulkollan seals: they stayed intact for 1 year, even in Brazil’s hot, humid climate.

For a European solar farm, Vulkollan mounting pads secured panel frames. Unlike rubber pads that cracked under UV exposure in 12 months, Vulkollan pads remained flexible after 5 years, protecting panels from wind vibration.

IV. Customizable to Fit Exact Job Needs

As a custom manufacturer, we don’t just supply off-the-shelf Vulkollan parts. We tailor them to your equipment’s unique requirements:

  • Hardness: 70A (flexible for seals) to 95A (rigid for load-bearing parts)
  • Shapes: Complex designs (wear strips, grooved rollers & wheels, tapered seals, custom gaskets)
  • Surface finishes: Smooth for sealing, textured for grip (e.g., forklift wheels)

Real Application: A French food processing plant needed Vulkollan scrapers for their bread dough mixers. The scrapers had to be food-safe (FDA-compliant), flexible enough to reach mixer corners, and tough enough to resist dough buildup. We customized 80A Vulkollan scrapers with a slightly textured edge—they’ve been in use for 14 months, with no need for replacement.
