Biosynthetic Technologies offers high-performance estolide based products as additives or cosolvents in metalworking fluid applications. Our products can be easily used in different metalworking fluid types such as straight oils, cutting oils, emulsifiable oils, semisynthetic fluids, and synthetic fluids. As a cosolvent or additive, our products offer exceptional features and benefits when formulated into a metalworking fluid.
These benefits include
- Enhanced lubricity
- Exceptional wear protection
- Excellent hydrolytic stability (across pH 4-10)
- Reduced friction, better cooling
- Assists with chip removal
- Improved tool life and efficiency
- Remarkable solvency
- Increased polarity
- Enhanced film strength
- High thermal stability
- Outstanding oxidative stability
- Non-toxic
- Significantly improves overall worker safety
- Bio-based (vegetable derived)
- Biodegradable
- REACH registered and polymer exempt
- HX1 certified
- Naturally low foaming
- Compatible with many metal alloys
Biosynthetic Technologies also offers other castor derived high-performance fluids that are natural and sustainable. Our extensive bio-based product line is specifically formulated to match formulator needs and to provide solutions to the many distinct challenges in the metalworking fluid market. We offer the following castor derivatives in our metalworking product line.
| Property | BT PRA30 | BT PRA40 | BT PRA50 | BT PRA100 |
|---|---|---|---|---|
| Total Acid Number (mg KOH/g) | 30-35 | 38-42 | 48-52 | 98-102 |
| Gardner Color | 8 max | 8 max | 8 max | 8 max |
| Pour Point (°C) | < -10°C | < -10°C | < -10°C | < -10°C |
| Flash Point (°C) | > 230°C | > 230°C | > 230°C | > 230°C |
| Viscosity (cSt at 100°C) | 83.5 | 62.28 | 48.98 | 21.96 |
These castor derived products perform exceptionally well in a variety of functions, and often represent formulation improvements that offer greater product uniformity and cost savings. All our castor oil derivatives have sales approval for US (EPA), Canada (CEPA), and Europe (REACH).
