On the spectrum of modified silicone emulsions, pure methyl silicone emulsion is too water-philic and bleeds, pure phenyl emulsion is costly and film-hard, polyether silicone emulsions char at high temp. As die-casting Al/Mg molds hit 300℃+, high-speed fiber spinning demands "oil film no char no drip," and metal water-based lube needs "organic-affinic no separation," an emulsion—
milky liquid, 50±2% solids, long-chain alkyl + arylalkyl co-grafted PDMS, nonionic stable, low-carbon film at high temp—emerges as the factory-grade lube-release anchor folding "siloxane heat + long-chain oil adherence + aryl anchoring" into O/W interface.
Addressing this "arylalkyl graft" slot,
Anhui IOTA Silicone Oil Co., Ltd. (IOTA) releases
IOTA-28027E Aryl Alkyl Polysiloxane Emulsion. Defined by core parameters—
long-chain C16-22 alkyl + benzyl/phenethyl arylalkyl co-modified silicone oil as oil phase, advanced homogenization, film with slip/hydrophobic/low-char—it carries the triple attributes of
"high-temp no-char + organic compatibility + low-residue die casting," serving as the "arylalkyl slip-film anchor" for die-cast release, metal hot lube, plastic modification, filament spin finish, and personal care conditioning.
Emulsion Architecture: PDMS–(Long Alkyl + Aryl) Graft + Nonionic O/W
IOTA-28027E oil phase is not a simple blend but
copolymer where some methyls on PDMS are replaced by long-chain alkyl (C16-22) and arylalkyl (benzyl/phenethyl):
-
Long Alkyl Oil-Adherent: Side-grafted C16-22 lowers contact angle on metal, the hot film "bites" the mold under high-pressure shot, no回流 no droplet pooling; vs pure methyl silicone, adhesion and load-bearing film strength rise markedly—fits die-cast high-pressure flush.
-
Aryl/Arylalkyl Heat Anchor: Phenyl conjugation absorbs thermal energy; arylalkyl buffers thermo-oxidation; at 250-320℃ mold temp no cracking, carbon residue far below mineral-oil release (low char = less mold cleaning, fewer casting pores).
-
PDMS Backbone Slip: Enough siloxane left gives low friction, high gloss, hydrophobicity (>100° contact angle) post-film, part surface non-harsh non-tacky.
-
50% Nonionic Emulsion: Nonionic bed, centrifugal-stable, cold-water dilutable, partially oil-compatible; 50±2% solids lifts transport and spray efficiency, site dilution 1:5–1:20 ready.
Performance Leap: From Single Release to High-Temp Lube Same Body
In die-cast release, metal hot rolling, and filament spinning lines, 28027E pays off at once:
-
Die-Cast Low-Char Release: Al/Mg/Zn die casting spray, mold temp 250-320℃ water flashes, silicone films; stable ejection force, clean casting surface, mold carbon cycle extended multiples vs soap wax/mineral emulsion.
-
Metal High-Temp Lube: Hot forging, extrusion, screw lube water carrier—no flash fire, no coke, cools and lubes.
-
Fiber Spin Finish Component: Polyester/nylon high-speed spinning (3500 m/min+) blend, gives cohesion/smoothness/antistat synergy, no yellow char on hot godet (180-220℃).
-
Plastic Internal Slip: PP/PE/PA internal slip (break emulsion, adsorb on powder, then melt-disperse) lowers screw torque, lifts antiblock.
-
Personal Care Conditioning: Hair/skin poly-siloxane emulsion upgraded to oil-affinic version; long alkyl spreads, aryl glosses, silicone feel without fake slip.
Application Penetration: From Die-Cast Mold to Shampoo Bottle
IOTA-28027E precisely lands on the interface needing
"high temp + metal + organic affinity":
-
Die-Cast & Hot Work: Al die cast, Mg semi-solid, hot forge, continuous caster mold lube.
-
Metal Working: Rolling emulsion additive, screw compressor water lube.
-
Polymer Processing: Filament spin finish, plastic slip/antiblock, masterbatch dispersant.
-
Daily & Oil: Hair conditioner, skin silicone modifier, industrial oil antiwear aid.
Die-cast release blenders read 28027E plainly: it welds "long-alkyl metal adherence + aryl heat-low-char + siloxane slip hydrophobic" into one 50% emulsion; Al/Mg shops no longer compromise between "pure methyl silicone bleed" and "mineral oil coke mold," and fiber plants need not self-emulsify pricey aryl silicone—one drum 28027E trials across hot-mold release, metal lube, and spinning cohesion.
