Next Stop: Mexico! | Invitation to RALLYCHEM at PLASTIMAGEN® 2026

Heading to Mexico—
let’s have a practical conversation.
From November 10–13, 2026, the International Plastics Exhibition for Mexico (PLASTIMAGEN® 2026) will take place at Centro Banamex in Mexico City. You can find RALLYCHEM at Booth 3020 in Hall A.

Rather than just handing you another product catalog, we’d like to use this opportunity to discuss the specific challenges you face in your production processes.
If you are involved in plastics modification or product manufacturing, the following four scenarios might sound familiar.

01
Does your current wax still work when the process changes?

The same material experiences different shear forces, temperatures, and residence times depending on whether it is processed via injection molding or extrusion. It’s common to see an extrusion line running smoothly, only for the same material to cause mold sticking, weld lines, or even slight degradation when switched to high-speed injection molding.
This usually isn’t a case of “not enough wax.”
A simple rule of thumb: if your product sticks to the mold or has a dull surface, it often suggests an excess of external lubricant; conversely, if the melt is sluggish, poorly plasticized, or shows prominent weld lines, it may indicate a lack of internal lubrication.
We don’t believe in a “one-wax-fits-all” approach. Instead, we prefer to match the right type of lubricant to your specific screw configuration and molding method.
Relevant products: Polyethylene wax, oxidized polyethylene wax.

02
Does higher filler loading always make dispersion more difficult?

In highly filled systems, the significant difference in surface energy between the filler and the resin often makes it difficult to break up agglomerates through mechanical shear alone. Oxidized polyethylene wax acts as a “bridge”—one end has an affinity for the filler surface, while the other is compatible with the resin.
Identifying this is straightforward: if you notice white spots on the product’s cross-section, significant fluctuations in melt pressure, or unstable screw torque, the issue likely lies in the dispersion stage—before you jump to the conclusion that there’s a problem with your equipment. We tailor the acid value and molecular weight of our additives to the specific type and loading level of the fillers used, rather than applying a “one-size-fits-all” formulation to every system.

03
When an end customer asks for:
“More matte, smoother, and more scratch-resistant”

These three requirements translate into three distinct technical parameters: gloss, coefficient of friction, and surface hardness—each requiring a different additive strategy:
• For a more matte finish: The particle size and distribution of micronized waxes are key. Larger particle sizes and narrower distributions yield a more uniform matte effect.
• For greater smoothness: Migratory waxes create a lubricating layer on the surface. Too much can lead to blooming (exudation), while too little may fail to provide the desired tactile feel.
• For improved scratch resistance: Waxes with high melting points and high crystallinity help increase surface hardness, though this may affect transparency.

If your requirements are difficult to quantify, feel free to bring a sample! We can work with you to reverse-engineer the ideal formulation based on the specific tactile feel you need.

04
After changing raw materials,
is your original formulation still effective?
Changes in raw material sources or the inclusion of recycled content—common scenarios for companies in Mexico—may necessitate a re-evaluation of existing additive packages.
This doesn’t necessarily mean the original formulation was flawed; rather, the compatibility window of the system has shifted. A wax that performed perfectly in the original setup might now be present in an insufficient or excessive amount.
Therefore, after switching raw materials, we recommend conducting a small-scale trial, focusing on three key indicators: changes in melt flow rate (MFR), surface blooming (exudation), and any degradation in mechanical properties. If these three factors remain stable, your formulation is likely reliable.
We are bringing six specific products to Mexico.

You define the requirements—we’ll provide the solution.

Our booth is ready.
See you in Mexico! If convenient, we suggest bringing the following three pieces of information:
Your current system:
Resin grade, type of filler, and its loading level (percentage).
Current challenges:
High torque, poor surface finish, uneven dispersion, or blooming/yellowing.
Desired outcome:
Even a simple description, such as “the tactile feel is not quite right,” is helpful.
Please visit us at Booth 3020 in Hall A. We will discuss your specific situation and provide initial guidance—offering immediate solutions where possible, or registering your requirements for sample testing and follow-up after the exhibition.
