Product Description

Pain point you may have faced
Polar rubbers like FKM, ACM, or HNBR are notoriously difficult to process. The compound is stiff, mixing takes forever, and your internal motor draws high amps. On the open mill, the stock sticks to the rolls – you waste time scraping and cleaning instead of producing. Extrusion is slow, demolding is a struggle, and surface defects are common. You have tried other process aids, but they often compromise cure or leave residues that harm the rubber’s heat and oil resistance.

Why LF‑36 is different
First® LF‑36 is a specialty flow dispersant engineered specifically for polar elastomers, including FKM, ACM, AEM, ECO, CSM, HNBR, and EO. It rapidly reduces the Mooney viscosity of the compound, allowing the internal mixer to run shorter cycles and consume less energy per batch. More importantly, it eliminates the sticky‑roller phenomenon – the compound releases cleanly from the mill, so you can focus on production, not cleaning.

What you gain on the extrusion and molding floor

Shorter mixing time – lower energy bills, higher mixer throughput.

Higher extrusion rate – the compound flows faster and more evenly through the die.

Easier demolding – parts release cleanly without sticking to the mould, reducing cycle time.

Smooth, uniform surface finish – no more rough edges or flow marks.

Increased injection and extrusion output – overall production capacity rises without adding equipment.

No negative impact on vulcanization or properties
Unlike some processing aids that slow down cure or soften the vulcanizate, LF‑36 does not affect curing speed nor degrade the critical physical properties of polar rubbers – heat resistance, oil resistance, and compression set remain fully intact.

Real‑world result
An ACM automotive hose manufacturer had constant issues with mill sticking and slow extrusion. After switching to First® LF‑36 at 1.5 phr, the mill became clean, extrusion speed increased by 22%, and demolding became effortless. Their scrap rate dropped from 6% to under 2%, and they saved about 18 kWh per mixing batch.
