Product Description

Overview

Petropec Silicone Oil is a premium polydimethylsiloxane (PDMS) fluid engineered for demanding industrial, manufacturing, and Petropec applications. Its superior lubrication, dielectric strength, and release properties make it a versatile solution for sectors requiring heat resistance, chemical inertness, and surface protection.

Key Features

• Exceptional Mold Release Performance – Forms a micro-thin, non-carbonizing film for easy part release.
• Thermally Stable – Effective from -50°C to +200°C without breakdown.
• Chemically Inert – Compatible with metals, plastics, elastomers, and most chemicals.
• Low Surface Tension – Spreads evenly for uniform coverage and minimal usage.
• Hydrophobic – Repels water and moisture.
• Multiple Viscosities Available – 100, 350, 500, 1000, 12,500, 60,000, 100,000 cSt.

Applications

1. Mold Release Agent

• Plastic Injection Molding – Facilitates easy ejection of molded parts without residue.
• Rubber & Elastomer Molding – Prevents sticking and tearing during demolding.
• Die Casting – Reduces wear on molds and extends tooling life.

2. Lubrication & Anti-Seize

• Bearings, gaskets, O-rings, and seals in high-temperature and chemically aggressive environments.
• Valves and fittings in oil & gas pipelines.
• Anti-foaming.

3. Dielectric & Electrical Insulation

• Used as transformer oil, capacitor fluid, and insulating medium.
• Protects electrical connections in damp or corrosive environments.

4. Hydraulic & Damping Fluid

• Instruments, dashpots, and precision equipment requiring stable damping across temperature ranges.

5. Surface Protection & Water Repellency

• Forms a thin film that protects metals, glass, plastics, and ceramics from moisture, dust, and corrosion.

6. Heat Transfer Fluid

• Stable in closed-loop systems for controlled heating and cooling processes.
