Engineering Plastic Modification

Соответствует температурной стойкости при переработке инженерных пластмасс

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.

Frequently Asked Questions

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.

Rallychem will provide you with professional consulting services, PVC/CPVC customized solution and products including wax additives, wax emulsions, micropolymers customized production,etc. Welcome to contact us.
