 
Mold-On Rubber on Glass-filled Nylon
This wheel type is ground-breaking to the industry, and spells the end for “Rubber on Cast Iron”! Durastar is your first and only source of this amazing wheel. Glass-filled Nylon is chemically engineered to specifically replace Cast Iron cores, such as Moldon Rubber on Cast Iron wheels. There is NO COMPARISON IN PERFORMANCE! Consider the benefits:
- Same capacity
- Molecular bond prevents debonding
- Greater impact absorbtion
- No rust or core decay
- Resists water, oils, alkalines, and chemicals
- Lighter shipping weight
- Production is more environmentally friendly than steel
- More cost efficient than steel

Material Features
- The inner core is a fiberglass-like resin that resists most chemicals, solvents, salts, grease, alkalines, and steam cleaning. Will not rust, oxidize or decay, as cast-iron does. Will absorb much more abuse.
- The outer tread is an elastic mold-on rubber of exceptional grade.
Production Process
Nylon does not naturally repel rubber. Combination of these two elements is easy and further promoted by select-formula chemical bonding. The core is masterfully engineered for high-impact with proper curve degree in the support columns, and is further strengthened with staggered column positioning on opposing sides.

Impact Test
Consider a quick, simple evaluation comparing wheel impact absorption in the following video series. We chose the most vulnerable Glass-filled Nylon wheel size: 8”x 2”. Therefore, this comparison involves an 8x2 wheel of both varieties. Effort was made to inflict equal, consistent blows throughout the process.
