VANFRE® L20
Processing Aids
VANFRE® L20 provides outstanding performance for most elastomers as a dispersing aid for commonly used fillers in rubber compounding. It also works very well as an internal release agent in injection and transfer molding, preventing sticking of compounds to rolls and rotors. VANFRE L20 does not adversely interfere with most curing systems. Due to its low dosage level there is hardly any or no effect on physical properties. Recommended dosage: 1 to 5 phr.
