Food-Grade Polyurethane Timing Belts (FDA)
Food-Grade Polyurethane Timing Belts (FDA)
Food-grade polyurethane timing belts are manufactured from FDA 21 CFR 177.2600 compliant materials for direct food contact in food processing, pharmaceutical, and medical applications. They are available with sealed stainless steel tension members for continuous washdown environments and in blue detectable material for visual and optical contamination detection on production lines.
Texas Belting stocks food-grade belts in AT-Series profiles (AT3, AT5, AT10), ATP10, and T-Series profiles (T5, T10). All food-grade belts are also available in self-tracking, double-sided, and profiled configurations. Texas Belting also stocks rubber food-grade timing belts from Gates and Continental.

Food-Grade Material Options
Five material compounds are available, each with different properties for specific food industry requirements. Choose based on whether the application involves dry goods, wet processing, or full washdown environments.
| Material | Color | Hardness | FDA 21 CFR | EU 10/2011 | Washdown Rated | Best For |
|---|---|---|---|---|---|---|
| FDA1 | Natural (off-white) | 88 Shore A | Yes | Yes | No | General food contact, dry goods, packaging |
| FDA2 | Blue (detectable) | 92 Shore A | Yes | Yes | No | Meat, dairy, bakery with visual detection |
| AU1 | Clear | 92 Shore A | Yes | Yes | Yes | Wet processing, continuous washdown |
| AU2 | Clear | 95 Shore A | Yes | Yes | Yes | Heavy-duty washdown, high abrasion |
| Sealed Blue | Blue (detectable) | 92 Shore A | Yes | Yes | Yes | Full washdown with visual detection (highest spec) |
Hygienic Design Features
| Feature | Benefit |
|---|---|
| Sealed stainless steel tension members | No exposed metal; prevents bacterial harbor points and corrosion contamination |
| Smooth, non-porous surface | Easy to clean; resists microbial growth; does not absorb cleaning chemicals |
| Hydrolysis-resistant compounds (AU1, AU2) | Withstands hot water, steam, and CIP (Clean-In-Place) cycles without degradation |
| Blue detectable material (FDA2, Sealed Blue) | Visible to both human inspectors and optical detection systems if belt fragments enter product |
| No fabric reinforcement on belt surface | Eliminates fiber contamination risk that fabric-backed belts can introduce |
| Self-tracking option | Eliminates flanged pulleys, removing hard-to-clean crevices from the drive |
Industry Applications
Food-grade polyurethane timing belts are used across the food, beverage, pharmaceutical, and medical industries wherever FDA compliance and hygienic belt operation are required. Key applications include:
| Industry | Typical Applications | Recommended Material |
|---|---|---|
| Food processing | Sorting, conveying, slicing, portioning equipment | Sealed Blue or AU1 |
| Food packaging | Form-fill-seal, case packing, labeling, cartoning | FDA1 or FDA2 |
| Brewery and beverage | Bottling lines, canning, labeling, case packing | FDA2 or AU1 |
| Pharmaceutical | Tablet presses, blister packaging, vial filling | AU1 or AU2 |
| Dairy processing | Filling, capping, conveying in wet environments | Sealed Blue |
| Meat and poultry | Portion cutting, conveying, tray sealing | Sealed Blue |
| Bakery and confectionery | Oven exit conveyors, depositing, wrapping | FDA2 (or GEN III for heat) |
Frequently Asked Questions
The belts are manufactured from polyurethane materials that comply with FDA 21 CFR 177.2600 and EU Regulation 10/2011 for food contact. Multiple material grades are available depending on whether the application involves direct food contact, washdown cleaning, or dry operation. Certificates of compliance are available upon request for each material compound.
Blue is not a naturally occurring color in food products, which makes belt fragments visually detectable by both human inspectors and optical detection systems on production lines. If a belt fragment enters the product stream, the blue color makes it easy to identify and remove before the product reaches consumers. Blue detectable belts are available in both dry-contact (FDA2) and full washdown (Sealed Blue) grades.
Yes, but only specific compounds are washdown rated. AU1, AU2, and Sealed Blue compounds have high hydrolysis resistance and are formulated for continuous washdown with hot water, steam, and common food-industry sanitizers. FDA1 and FDA2 compounds are intended for dry food contact applications. Always pair washdown-rated compounds with sealed stainless steel tension members.
Food-grade polyurethane is available in AT3, AT5, and AT10 curvilinear profiles, ATP10 high power profile, and T5 and T10 trapezoidal profiles. These can be configured as self-tracking, double-sided, or with welded profiles for conveying. Contact Texas Belting at 888-203-2358 for specific profile and width availability.
Food-grade polyurethane belts can be cleaned with hot water, steam, and most common food-industry sanitizers. The non-porous surface resists microbial growth and does not absorb cleaning chemicals. Washdown-rated compounds (AU1, AU2, Sealed Blue) can withstand regular CIP (Clean-In-Place) cycles without degradation. Avoid using solvents not listed in the chemical resistance guide.
Yes. FDA-compliant polyurethane belts operate down to -30°C, making them suitable for frozen food processing and cold storage conveying. The polyurethane remains flexible at low temperatures without cracking, unlike some rubber compounds.
Standard FDA-grade polyurethane belts operate continuously up to +80°C. For applications near ovens or in hot-fill processing, Redflex GEN III compounds extend the range to +100°C, though GEN III is currently separate from FDA-certified materials. Contact Texas Belting at 888-203-2358 to discuss options for high-temperature food applications.
For dry food contact or packaging (no wet cleaning): FDA1 (natural) or FDA2 (blue detectable). For wet environments with regular washdown: AU1 or AU2 with sealed stainless steel cords. For the highest specification combining washdown capability with visual detection: Sealed Blue. Contact Texas Belting at 888-203-2358 with your application details for a material recommendation.
