New Product Preview | High-performance polyester wax brings a better solution to engineering plastics processing

Have you encountered these problems in engineering plastics processing?

1. The same formula works well today, but becomes unstable tomorrow?
2. Transparent products become foggy or show precipitation, affecting their appearance?
3. Molds are becoming increasingly difficult to release, increasing equipment load?
4. Product batches fluctuate greatly, but the cause cannot be found?

Many companies’ first reaction is to adjust the main raw material.

However, the actual problem often lies not in the main raw material, but in an easily overlooked area—additives.

Among these, waxes are the most widely used and have the most direct impact: they affect lubrication and flow, and directly determine demolding, surface condition, and product consistency.

However, natural waxes have a core problem—instability: Raw material fluctuations lead to batch differences, impurity changes cause precipitation and fogging, and unstable supply further amplifies costs and production risks.

Therefore, what customers really need is not just a “usable” solution, but a long-term, stable, and controllable one.

Rallychem’s high-performance polyester wax series , addresses the problem structurally.

Based on an innovative α-olefin polymerization process, Rallychem’s high-performance polyester wax series precisely replicates the core molecular structure of natural montmorillonite wax while optimizing its performance.

Application-Oriented Approach: Structural Advantages and Their Reflection in Actual Processing

In engineering plastics and dispersion systems, Rallychem’s high-performance polyester wax series is primarily used in the following two typical scenarios:

Engineering Plastics Processing (PA/PC/PET/PBT/TPU)

• PA (Glass Fiber Reinforced) – Reduces torque fluctuations, improves equipment operating stability, and facilitates smoother demolding.
• PC/PET/PBT – More uniform dispersion, better flowability, and reduced sticking and surface defects.
• TPU – Low migration, maintains transparency, and reduces fogging and surface stickiness.

Masterbatch/Filler/Coating Systems

• More uniform dispersion
• Reduced color difference and particle size
• More stable batches
• More suitable for continuous production

More Than Just Reproduction, Targeted Optimization

The improvements in the above applications do not stem from a single performance enhancement, but rather from the synergistic effect of multiple key performance characteristics within the same system.

Focusing on core issues in actual processing, Rallychem’s high-performance polyester wax series has undergone targeted optimization in the following aspects:

• Lubrication Performance Optimization – More Stable Processing: Improved fluidity, reduced processing resistance, resulting in more stable processing.
• Dispersion Performance Optimization – More Uniform Appearance: Enhanced uniformity, reduced color difference and particle size.
• Temperature Resistance Optimization – Adaptability to High-Temperature Processing Systems: Compatible with high-temperature systems such as PC, PA, and PET, reducing the risk of decomposition and yellowing.
• Batch Stability Optimization – More Controllable Production: Reduced machine setup frequency, resulting in more controllable production.
• Alternative Solution Optimization – More Controllable Cost and Supply: Stable performance while maintaining controllable cost and supply.

Furthermore, the product possesses an advantage that natural waxes lack – Adjustability: Acid value and modification methods can be adjusted according to the resin system and process conditions to achieve a more suitable application effect.

More Than Just Replacement, It’s an Upgrade in Stability

Using Rallychem’s high-performance polyester wax series is not merely about changing a material; it’s about gradually shifting a processing method that previously relied on experience towards a stable and controllable production system.

We address practical production problems by starting with the chemical structure.

Domestically, we promote substitution and formula stabilization; overseas, we advance localized production and services.

Our path is clear:

R&D in China, manufacturing globally, and service locally.
