In the engineering plastics industry, many performance issues do not stem from the base material itself, but rather from those key additives that “seem inconspicuous yet determine processing experience and final product performance.”

For example, is lubricity sufficient? Is dispersion uniform? Is it stable under high-temperature processing? Is demolding smooth? Will transparent products suffer from fogging or migration?

What’s more, beyond performance, customers are increasingly concerned about another question: Are batch properties stable? Is the supply controllable?

Especially when natural materials face price volatility, inconsistent quality, and frequent impurity issues, the market no longer needs just a “usable” substitute. What it demands is an upgraded solution that offers stable performance, reliable application, and sustainable supply.

Based on this market need, RALLYCHEM’s high-performance polyester wax series has been developed.

Designed Specifically for Engineering Plastics: High-Performance Polyester Wax Series

RALLYCHEM’s high-performance polyester wax series uses an innovative α-olefin polymerization process to precisely replicate the molecular backbone structure of natural montan wax.

The value of this technical approach lies not only in “replication” but also in “optimization” —
while achieving dual improvements in product performance and batch stability, it also effectively avoids the small-molecule impurities commonly found in natural materials.

The end result is not just a single performance enhancement, but a comprehensive solution better suited to the processing needs of modern engineering plastics.

Why Is This New Product Worth Attention?

For engineering plastics customers, a truly valuable material is never one that looks “strong” on a datasheet, but one that performs stably in actual production.

RALLYCHEM’s high-performance polyester wax series focuses on optimization in the following key areas:

1. Excellent Lubricity
Helps improve processing flow, reduce system processing resistance, and enables smoother, more stable material performance during molding.

2. Superior Dispersibility
Exhibits good dispersion capability in pigment, filler, and functional additive systems, helping to enhance system uniformity and final product consistency.

3. Good Heat Resistance
Adapts to more demanding processing environments, maintaining stable performance under high-temperature conditions.

4. Stable Batches, More Controllable Application
Compared to natural-source materials, which are more susceptible to raw material fluctuations, the synthetic process ensures better product consistency and helps customers reduce application risks.

5. More Mature Replacement Strategy, Better Cost Performance
This series serves as a replacement solution for montan wax, offering customers a more competitive cost and supply chain option while maintaining reliable performance.

Adaptable to Multiple Scenarios, Covering Various Engineering Plastics Applications

The high-performance polyester wax series is not a single-point product that “only works in one formulation,” but a versatile material with strong adaptability.

It is currently widely applicable in the following areas:

Engineering Plastics Modification

Polyamide (PA)
Provides good compatibility, demolding properties, and flow promotion. Suitable for glass-fiber-reinforced PA systems, helping improve processing performance and finished product quality.

Polycarbonate (PC), Polyesters (PET/PBT), and other systems
Helps improve flow and demolding in filled systems, further enhancing surface quality and production efficiency.

Thermoplastic Polyurethane (TPU)
Provides long-lasting, non-migrating demolding and anti-blocking effects, especially suitable for TPU products with high transparency requirements.

Stable Performance in Pigment and Filler Dispersion

Beyond engineering plastics modification, the high-performance polyester wax series also performs well in pigment and filler dispersion.

Its good dispersion capability makes it suitable for producing high-concentration, dust-free masterbatches and functional masterbatches, with particular advantages in applications such as PET fiber masterbatch.

For customers seeking dispersion efficiency, color consistency, and processing stability, this type of additive often delivers direct improvements to process performance.

Promising Performance in Transparent PVC Processing

In PVC processing, especially transparent product manufacturing, this series also demonstrates high application potential.

Compatibility and Transparency
Exhibits high compatibility in transparent PVC extrusion and can be used as an internal/external lubricant and demolding agent, helping achieve high transparency, no fogging, and no migration in finished products.

Thermal Stability
Maintains good thermal stability during high-temperature processing, preserving color and performance stability.

This means it not only improves the processing stage but also supports the appearance and quality stability of final products.

More Than a Replacement: An Application Upgrade

When many customers look for replacement solutions, their biggest concerns are not simply “can it be replaced?” but:

• Is the replacement performance stable?

• Are different batches consistent?

• Will the processing window narrow?

• Will subsequent supply be reliable?

• Can it truly help reduce costs and improve efficiency?

The value of RALLYCHEM’s high-performance polyester wax series lies precisely here.

It is not a mere “substitute,” but a more mature and robust solution developed based on real application needs.

It can serve as a replacement pathway for montan wax while helping customers achieve further optimization in the following dimensions:

• Improve product quality

• Optimize processing technology

• Enhance production efficiency

• Improve batch-to-batch consistency

• Strengthen supply chain resilience

Welcome to Experience This New Product at CHINAPLAS 2026

Facing the continuous demands of the engineering plastics industry for high performance, stability, and supply reliability, additive products are moving from “functional fulfillment” to “systematic optimization.”

RALLYCHEM’s high-performance polyester wax series is a new product launched precisely in response to this trend.

If you are focusing on:

• Montan wax replacement solutions
