From lubrication mechanisms and comparisons with paraffin/PE wax to Heyee Chem's full HY series real model specifications — a grade-selection reference written for formulation engineers.
Fischer-Tropsch Wax (F-T Wax) is produced via the Fischer-Tropsch synthesis from syngas (CO+H₂). It consists mainly of straight-chain alkanes and features a narrow molecular weight distribution, high purity, and white color. In PVC processing it serves primarily as an internal and external lubricant:
Compared with paraffin wax (broad molecular weight distribution, poor thermal stability) and ordinary PE wax, high-melting-point Fischer-Tropsch wax can significantly reduce extrusion torque and minimize bloom/exudation during high-speed extrusion of PVC pipes/profiles, which is especially important for stabilizer systems.

Oxidized Fischer-Tropsch wax introduces polar carboxyl groups, offering better compatibility with PVC emulsions and water-based coatings, making it a key grade for high-end internal/external lubrication:
| Model | Drop melting point | Acid value (mgKOH/g) | Form | Application |
|---|---|---|---|---|
| HY-9128 | 102℃ | 27–30 | Off-white coarse powder | Emulsion, leather, coating |
| HY-100-28 | 100–105℃ | 27–30 | Off-white microbead | Emulsion, PVC |
| HY-104-28 | 95–102℃ | 27–30 | Off-white microbead | Emulsion, PVC |
| HY-105-32 | ≥105℃ | 30–35 | Off-white microbead | High-end emulsion PVC |
| HY-B39 | >110℃ | 12–18 | Coarse powder | PVC lubricant |
PVC Stabilizer / Pipe / Profile High-Melting Powder → HY-W104, HY-102, HY-N100, HY-105
PVC Profile: Lubrication & Dispersion → HY-115 / HY-115P / HY-115M (Standard series)
Water-based / Emulsion / PVC Emulsion Lubrication → Oxidized Fischer-Tropsch wax HY-9128, HY-104-28, HY-B39
Low Melting Point: Rubber Protection / Cosmetics → HY-60+, HY-70 series
It depends on the melting point and polarity. Unoxidized high-melting-point Fischer-Tropsch wax (e.g., Heyee HY-W104 滴熔点≥117℃, HY-N100 滴熔点>110℃) acts mainly as a non-polar external lubricant, reducing melt adhesion to metal surfaces and improving demolding; oxidized Fischer-Tropsch wax (e.g., HY-9128, HY-104-28, 酸值 27-30) contains polar carboxyl groups, providing both internal lubrication and interfacial compatibility, and is better suited for PVC emulsion/water-based systems.
Yes. In practice, PVC formulations often blend Fischer-Tropsch wax with a small amount of paraffin to balance cost and processing performance; however, the paraffin ratio must be controlled, as excess will lower the system's thermal stability and increase bloom/exudation.
High-melting-point powder grades are preferred: HY-N100 (凝点≥99℃, 滴熔点>110℃, 针入度<2), HY-102 (凝点 99-103℃, 滴熔点>110℃), HY-W104 (凝点 102-108℃, 滴熔点≥117℃), benchmarked against international C105/W104 grades, suitable for high-speed extrusion of PVC heat stabilizers, pipes, and profiles.
Heyee Chem (Zibo Heyee Fine Chemical Co., Ltd., established in 2010, located in Hongyuan Chemical Industrial Park, Gaoqing County, Zibo, with an annual capacity of 60,000 tons) products hold ISO 9001, ISO 14001, REACH, FDA, RoHS, SGS and other certifications, and provide MSDS and COA.
Heyee grades benchmark against top-tier international equivalents. For example, HY-W104 benchmarks against C105, HY-115 against standard H1, HY-W80 against C80, HY-9128 against A18, HY-104-28 against A28 (data subject to the official complete benchmark table).
