01
Rubber & tire formulators
Tires, tread, mechanical rubber goods, latex and technical elastomers
ZINCOSIL active zinc oxide is used because organic accelerator systems generally need an activator to build an effective crosslink network. Higher surface area can increase zinc availability, so the formulator may be able to screen a lower addition than conventional zinc oxide while preserving cure and physical properties.
Where & why it is used
Sulfur-cured NR, IR, BR, SBR, NBR, IIR and EPDM compounds
CR, CSM, latex and selected metal-oxide or peroxide cure systems
Tire tread, sidewall, molded parts, seals, hose, footwear and spring components
Zinc stearate as an internal lubricant, dusting or anti-stick aid in rubber and EVA
Why it matters · what to validate
Cure curve, scorch safety, modulus and state of cure
Tensile, elongation, tear, hardness, abrasion and flex fatigue
Heat aging, heat buildup, rebound and compression behavior
Dispersion, microwave-cure defects, appearance and zinc cost per finished compound
02
Polymer compounders
Masterbatch, polyolefins, engineering plastics, film and molded parts
Metallic stearates are used at the resin–equipment and pigment–polymer interfaces. Depending on the metal soap and grade, they can neutralize acidic catalyst residues, lower internal or external friction, improve dispersion, reduce sticking and help powders or pellets remain free flowing.
Where & why it is used
PE and PP color, white, UV and filler masterbatch
HDPE, EVA, polystyrene, ABS, SAN, polycarbonate and nylon processing
Film, injection molding, extrusion, compounds and specialty polymer composites
Zinc, calcium, magnesium, sodium and lithium stearate screening routes
Why it matters · what to validate
Torque, melt pressure, throughput and processing-temperature window
Dispersion, color development, specks, plate-out and die buildup
Mold release, blocking, surface finish and downstream print or bond performance
Heat stability, mechanical properties, odor, volatiles and regulatory fit
03
PVC & cable formulators
Rigid and flexible PVC, pipe, profiles, WPC, foamboard and wire & cable
Calcium, zinc, barium, potassium and sodium stearates can serve as lubricants, acid scavengers or components of stabilization packages. They are important because PVC sees substantial heat and shear during fusion; the balance between lubrication and stabilization influences color hold, fusion, output and long-term properties.
Where & why it is used
PVC pipe, profiles, sheet, flooring, wall panels, WPC and foamboard
Flexible compounds, cable insulation and jacketing
Calcium stearate for lubrication and acid scavenging
Barium, zinc, potassium or sodium stearates only within a validated stabilizer design
Why it matters · what to validate
Fusion time, dynamic thermal stability and initial color
Torque, output, plate-out, surface gloss and dimensional control
Electrical, tensile, elongation and aging requirements for cable
Regulatory and heavy-metal restrictions for the exact end use and geography
04
Coatings & construction formulators
Wood finishes, paints, cement coatings, composites and building materials
The stearate chemistry changes the surface interaction of pigments, fillers and mineral substrates. Zinc stearate supports sanding and drawdown in wood sealers, aluminum stearate builds anti-settling structure, and calcium or aluminum stearate can increase water repellency in cementitious systems.
Where & why it is used
Sanding sealers, wood coatings, industrial paints and latex-paint dispersion
Cement paints, wall putty, mortar, concrete and waterproofing treatments
SMC/BMC, FRP and other fiber-reinforced composite processing
Powder or chemical coatings where free flow and moisture resistance matter
Why it matters · what to validate
Sanding response, clarity, drawdown, leveling and film appearance
Suspension, storage stability, settling and redispersibility
Water absorption, beading, adhesion and weathering in construction materials
Composite release, fiber wet-out, surface quality and mechanical properties
05
Industrial specialty formulators
Grease, petroleum, powder treatment, paper and process aids
Lithium and aluminum stearates build or modify grease structure, while selected stearates can provide hydrophobicity, corrosion-inhibitor support, powder flow, emulsification, sizing or dispersion. Their importance is the repeatable control of rheology and interfaces—not simply adding a generic metal soap.
Where & why it is used
General-purpose lubricating greases and petroleum formulations
Moisture-resistant or free-flow surface treatment of powders
Paper and paperboard sizing, wetting and dispersion
Industrial emulsions, process aids and application-specific hydrophobic treatments
Why it matters · what to validate
Worked penetration, dropping point, oil separation and mechanical stability
Water washout, corrosion protection, oxidation and bearing compatibility
Powder flow, caking, coating uniformity and moisture pickup
Emulsion stability, foaming, wetting and downstream product consistency
06
Document-controlled formulators
Cosmetics, pharmaceutical, food-contact and other regulated uses
Several MLA technical sheets identify cosmetic, pharmaceutical or food-related starting uses for selected stearates. In these markets the additive is important for lubrication, tableting, stick structure, feel, dispersion or processing—but chemistry alone does not establish regulatory suitability.
Where & why it is used
Magnesium stearate as a pharmaceutical processing ingredient
Sodium stearate for cosmetic-stick gel structure
Zinc, potassium, calcium or lithium stearates in selected specialty formulations
Ceramics, paints, cosmetics, agriculture, animal feed or food-contact uses only against exact current grade documentation
Why it matters · what to validate
Compendial or food-contact status, GMP and change-control documentation
Elemental impurities, microbiology and customer-specific specifications
Sensory profile, whiteness, particle size, consistency and traceability
Written regulatory confirmation for the grade, use level, region and final article

MLA Group technical answers
What formulators ask first.
Which MLA Group technologies are being developed for North America?
The platform includes active zinc oxide and metallic stearates for rubber, plastics, PVC, coatings, construction, grease and selected specialty applications. Grade-level details require verified access.
Can one metallic stearate replace another?
No. The metal, particle structure, moisture, melt behavior, free fatty matter, regulatory package and manufacturing process determine performance in the final formulation.
How does Henneke Holdings support an MLA additive trial?
Henneke Holdings defines the incumbent material, formulation, required documents, sample plan and pass/fail criteria, then coordinates technical and commercial follow-through after account verification.
Access, claims and qualification status
MLA Group project intake is accepted; availability, territory and project terms are confirmed case by case. Product documentation, pricing, regulatory status and supply are also confirmed for each project. Manufacturer statements are screening inputs, not guarantees. Customers must qualify the exact grade in the actual formulation, process and end use.
Application lab · technical + procurement
How to qualify MLA Group active zinc oxide and metallic stearates.
Rubber cure activation, zinc-efficiency studies, polymer and PVC lubrication, acid scavenging, release, rheology and specialty process control.
Why request a sample
A sample answers the questions a datasheet cannot.
Active zinc oxide cannot be qualified from ZnO assay alone; surface area, particle form, dispersion and cure-package interaction control the actual response.
Metallic stearates with the same metal can differ in free fatty acid, moisture, particle size, bulk density and process, changing lubrication, fusion, release and plate-out.
A sample ladder lets technical teams find the minimum practical use level while procurement measures compound cost, zinc use, cycle time, scrap and finished properties.
What to send first
Better intake creates a faster, more useful trial.
Rubber or polymer type, cure/stabilizer package, fillers, plasticizers, process aids and current additive grades
Current phr or percentage, mixing sequence, temperature history, fusion/cure conditions and production equipment
Heavy-metal, regulatory, electrical, color, transparency and end-use restrictions
Controlled comparison
Use one baseline, one written plan and measurable pass/fail gates.
01
Lock the full incumbent formulation and mixing procedure. Change only the zinc oxide or stearate in the first screening series.
02
For active zinc oxide, run an incumbent control plus a conservative dosage ladder; measure cure and scorch before molding full property specimens.
03
For metallic stearates, compare equal dosage first, then optimize around torque/fusion, release, plate-out, surface quality and stability.
04
Repeat the preferred formulation, age the compound where relevant and confirm it at normal production shear, temperature and cycle time.
Procurement gate
Qualify the supply package, not only the chemistry.
Specify chemistry, grade, production route where performance-critical, current TDS/SDS and COA limits for assay, moisture, free acid, particle size or surface area.
Calculate cost per passing compound at the qualified phr or percentage, including cycle time, scrap, deposits, maintenance and zinc reduction.
Confirm heavy-metal and regulatory documentation, manufacturing site, packaging, dust handling, shelf life and lot traceability.
Set change-notification, complaint testing, retained-sample, lead-time, minimum-order and supply-continuity requirements.
Sample ladder
Request enough material for a decision—not just one attractive result.
Stage 1 — enough for the incumbent control, dosage ladder, cure/fusion screening and retained sample.
Stage 2 — a second lot for complete physical, aging, stability and repeatability testing.
Stage 3 — production quantity for normal mixing and processing equipment, including startup, purge and repeat validation runs.
Decision ruleDo not approve on assay, cure time or torque alone; the same formulation must pass processing safety, finished properties, aging and total compound economics.
