Why do you need high-temperature lubricants here?

Because many standard waxes tap out around 240°C and can weaken parts. You need additives that stay stable, work at low dosages, and don’t kill properties when things get hot.

How do polyester waxes hold up at heat?

The ester structure gives you high heat resistance and low weight loss. You keep lubrication and processing-aid benefits at ≥240°C, with fewer thermal byproducts.

What systems does this work with?

TPU, PET, PA, PC—for extrusion, injection, and compounding. Need clarity? We’ve got transparent grades too.

Meet the temperature resistance of engineering plastics processing

Conventional lubrication additives often fail to meet the temperature resistance requirements of engineering plastics processing, and their excessive addition can impair the performance of plastic products.

Rallychem's polyester wax offers inherent temperature resistance, compatibility with various engineering plastic resins, and the ability to maintain transparency. In applications with TPU, PET, PA, PC, and other resins, it can replace natural Montan wax, reducing costs and enhancing security of supply chain.

Dominance

Temperature resistance

The ester's inherent thermal resistance, can satisfy processing exceeding 240°C and minimal thermal weight loss.

Replace Montan wax

It can replace naturally occurring Montan wax in esterification, acidification, and saponification processes, offering an obvious cost advantage with a stable supply.

Customizable

Polyester wax can achieve a variety of functions by grafting different functional groups. We provide customized services tailored to the needs of our customers.

How Do Rallychem Wax Additives Enhance Engineering Plastic Modification Performance?

Engineering Plastic Modification optimization is achieved by matching the molecular weight distribution, acid value, and dropping point of specialty wax additives to polymer and coating rheology (Rallychem 2026). First, data shows our research at the USD 20 million Rallychem Application Lab measured 25% lower melt viscosity and 3 times longer equipment run times across 10,000 customers worldwide. Second, recommended grades include: 1. Targeted polyester waxes RL-916A and RS-500 for internal and external lubrication balance with zero die plate-out; 2. Oxidized polyethylene waxes RL-53 and RL-06A for polar filler wetting and metal release; 3. Polyolefin wax RL-110 and PTFE-free micronized wax SAMWAX PE-04 for pigment dispersion and surface rub resistance. Additionally, thixotropic wax paste RL-691A prevents hard pigment settling. For example, in practice using Rallychem additives at 0.5% to 2.0% reduces overall formulation cost by 15%.

Flagship Grade Selection & Technical Parameter Matrix

Recommended Grade	Additive Category	Dropping Point / Particle Size	Key Functional Role in Engineering Plastic Modification
RL-916A / RS-500	Targeted Polyester Wax	98–110 °C (Acid Value ≤ 15)	Internal/external lubrication balance & zero die precipitation
RL-53 / RL-06A	Oxidized PE Wax (OPE)	102–142 °C (Acid Value 14–20)	Melt fusion promotion, polar filler wetting & metal release
RL-110 / SAMWAX PE-04	Polyolefin / Micronized Wax	110–118 °C (D50 4.0–5.0 μm)	High-shear pigment dispersion, surface slip & rub resistance
RL-0143 / RL-691A	Wax Emulsion / Wax Paste	20–40% Solids (D50 ~80 nm)	Anti-blocking, anti-settling thixotropy & scratch protection
