Petroleum Microcrystalline Wax is fully refined petroleum microcrystalline wax developed as direct drop‑in replacement for HYWAX 2528. It features dense microcrystalline structure, low oil content and excellent water‑repellent barrier property. For metal rust‑preventive formulations, it forms a hydrophobic protective wax film to block moisture and corrosive contaminants. Within hot‑melt adhesive systems, it adjusts melt viscosity and improves cohesive strength. It also serves as a high‑quality c

Product Detail

Product Overview

Petroleum Microcrystalline Wax (CAS 63231‑60‑7, HYWAX 2528 Equivalent) is fully‑refined petroleum‑derived microcrystalline wax obtained by vacuum distillation and solvent de‑oiling treatment. Its compact fine crystalline network provides outstanding water and moisture barrier performance. When used for metal rust‑preventive compounds, it creates a continuous hydrophobic wax coating that isolates steel surfaces from humidity, salt mist and atmospheric corrosion. In hot‑melt adhesive formulations, the wax modulates melt viscosity, optimizes solidification behaviour and reinforces internal cohesion of the adhesive matrix. For industrial candle manufacturing, it increases finished candle hardness, reduces surface sweating and improves shape stability during storage. This product acts as a cost‑effective imported substitute for HYWAX 2528 for rust‑proof compound, hot‑melt adhesive and candle manufacturers.

Key Features

Functional equivalent to HYWAX 2528 for imported‑grade substitution
Dense fine microcrystalline structure with low residual oil content
Excellent hydrophobic barrier property for metal anti‑corrosion and rust‑preventive systems
Adjusts melt viscosity and enhances cohesive strength for hot‑melt adhesive compounds
Improves hardness and shape stability for industrial candle articles, minimizing blooming
Good thermal stability with low‑sweating behaviour under moderate storage temperature
Excellent compatibility with paraffin wax, hydrocarbon resins and other wax modifiers

Technical Specification

Chemical Name: Petroleum Microcrystalline Wax
CAS Number: 63231‑60‑7
Appearance: Off‑white hard pellets or pastilles
Melting Point: 77‑84℃
Equivalent Grade: HYWAX 2528

Application Fields

Rust‑preventive coating and anti‑corrosion compounds for ferrous metal protection
General‑purpose industrial hot‑melt adhesive formulations
Industrial candle production blended with paraffin wax
Multi‑purpose industrial wax blends and specialty wax compounding

Usage Recommendation

For rust‑preventive wax‑based compounds, typical dosage ranges 12‑35 % of total formulation weight. For hot‑melt adhesive, suggested loading is 6‑17 %. For candle blending, addition is 3‑14 %. Complete melting and homogeneous stirring at controlled high temperature is required. It is strongly recommended to run laboratory trials before mass‑scale production to evaluate barrier performance, solidification characteristics and finished‑product stability.

Storage & Handling

Store sealed sacks in dry, well‑ventilated warehouse. Keep away from direct sunlight and high‑temperature heat sources. Prevent partial melting and caking. Reseal sacks promptly after partial discharging.

Safety Notice

This petroleum microcrystalline wax is intended for industrial manufacturing only, not suitable for food or cosmetic applications. Wear protective gloves and safety goggles during material handling. Please refer to the corresponding MSDS for complete safety operation instructions
