Castor oil is a bio-based lubricant derived from the castor bean. Its high lubricity and compatibility with many polymers make it useful in the plastic industry, especially in biodegradable systems and formulations sensitive to heat. It also serves as an efficient carrier for colorants and additives.
1.Can castor oil replace synthetic lubricants in plastics?
Yes, in many applications, castor oil provides comparable performance with added environmental benefits.
2.Is it suitable for high-temperature plastic processes?
Standard castor oil is ideal for moderate temperatures; modified versions are available for higher heat resistance.
3.Does castor oil affect polymer color or transparency?
It has minimal impact on color and is commonly used in masterbatch to enhance dispersion.
4.What polymers work best with castor oil?
It is highly compatible with PLA, PBAT, EVA, and TPU systems.
