Vulkollan® Thé ultimate elastomer!
It stands for high quality, long-lasting components.
Vulkollan® is the benchmark polyurethane elastomer in the market, combining excellent mechanical properties for highest dynamical load bearing capacity and abrasion resistance. That is why you will find Vulkollan® in the most demanding applications. No other type of polyurethane offers an optimal mix of properties over a wide temperature range.
- High damping: Vulkollan® wheels offer a low compression set for strong damping and high grip.
- Stable and rigid: Vulkollan® elastomers enable smooth rolling thanks to high material stiffness.
- Low heat build-up: Minimal heat build-up enables high-frequency acceleration and deceleration.
- Wear resistant: Load wheels made with Vulkollan® offer very high resistance to wear and tear.
- Low-maintenance: High abrasion resistance reduces wheel replacement and extends service life.
Vulkollan® can only be manufactured by licensed processors as VULKOPRIN. They produce wheels and castors to deal with highest dynamic loads, technical and semi-finished parts.
In a multistage process developed by Covestro (former Bayer Material Science), solid Vulkollan® is produced through chemical reactions between
- polyester polyols of the high-quality Vulkollan® range, Desmodur® 15
- and glycols.
Desmodur® 15 is the trade name for 1,5-naphthylene di-isocyanate (NDI) from Covestro. NDI is an essential curing agent for PU products. Unlike widely used diphenylmethane diisocyanate (MDI) and tolulene diisocyanate (TDI), NDI is with stiff structure and high melting point.
Thus, NDI-based cast polyurethane elastomers features not only more robust and durable, it also has superior physical properties, i.e. wear resistance and heat resistance.
The NDI-based elastomers combine the elasticity of an ether based material with the toughness of an ester based elastomer. Those NDI-based cast PU elastomers used in the automotive/transportation industries commonly to enhancing safety, which demand for both highest mechanical and dynamic load-bearing characteristics.
Reliable performance and maximum service life are the main distinguishing factors of Vulkoprin wheels made of Vulkollan® polyurethane:
- Temperature range: -40°C to +85°C, short-term to +120°C.
- 75, 80, 85, 92 or 95 Shore A
- Low rolling resistance
- Good grip
- High load capacity
- Vibration and sound attenuation
- Resistant to oils, greases and various chemicals
- Non-marking
- Wear-resistant
Suitable for medium to heavy transport on clean-, but also irregular- as floors in bad condition.
