Products in Maintenance, Repair & Overhaul: Release Agent

ULTRA-LUBE™ 888 is effective in improving flow properties of rubber compounds. The release effect of ULTRA-LUBE™ 888 is excellent during compounding and after curing as an internal mold release. ULTRA-LUBE™ 888 improves the dispersion of both carbon black and mineral fillers.

ULTRA-LUBET™ 160 is highly effective in improving flow properties of rubber compounds. This effect is based on a reduction of intermolecular friction and external friction against metal surfaces. ULTRA-LUBE™ 160 is outstanding during the compounding stage and after vulcanization as a mold release. Besides, it is highly effective as an internal release agent in preventing rubber compounds sticking to open mill rolls as well as to rotors in internal mixers. ULTRA-LUBE™ 160 has a stabilizing effect on the tendency of re-crystallization in CR compounds.

ULTRA-LUBE™ 230 shows outstanding performance as a dispersing aid for commonly used fillers in rubber compounding. In injection and transfer molding ULTRA-LUBE™ 230 leads to faster mold filling due to its internal lubrication. An improved mold release can also be observed. ULTRA-LUBE™ 230 also works very well as an internal release agent that prevents sticking of compounds to mill rolls, calendering bowls and internal mixer rotors. ULTRA-™ 230 has a higher solubility limit than ULTRA-LUBE™ 200.

ULTRA-LUBE™ 220 improves filler incorporation and release of most rubber compounds. Due to its low volatility, ULTRA-LUBE“ 220 can be used in heat resistant vulcanisates based on HNBR, ACM and FKM. ULTRA-LUBE™ 220 shows good plasticizing properties, which leads to reduction of injection pressure in molding process and prevents scorch. ULTRA-LUBE™ 220 is highly effective in polar compounds, like NBR to improve flow and release. ULTRA-LUBE™ 220 is especially suitable for peroxide curing system owing to its low peroxide demand.

Moulex® TPR is a semi-permanent water based release agent. It possesses high adhesivness on molds.

ULTRA-LUBE™ 200 is a processing additive for most rubber compounds. It shows outstanding performance as a dispersing aid for most fillers used in rubber compounding. In injection and transfer molding ULTRA-LUBET 200 leads to faster mold filling due to its internal lubrication. An improved mold release can also be observed. ULTRA-LUBE™ 200 also works very well as an internal release agent that prevents sticking of compounds to mill rolls, calendering bowls and internal mixer rotors. ULTRA-LUBE™ 200 does not adversely interfere with most curing systems. Due to its low dosage level there is little or no effect on physical properties of the finished goods.

Meretard PVI is 4,4’ Dithio dimorpholine compound which is used as sulfur donor in rubber industry.
