Ningdao Rubber Fluorosilicone – The Superior Choice for Oil and Chemical Resistance, Setting the Standard for Domestic Replacement of Imported Products

I. Product Overview

Ningdao Fluorosilicone Rubber, independently developed and manufactured by Ningdao Jiaoye, is a specialty silicone rubber engineered for extreme operating conditions. With superior oil resistance, chemical media resistance, high/low temperature performance, and consistent quality, it fully replaces comparable imported fluorosilicone products. Whether exposed to various oils and solvents or harsh environments such as acids and alkalis, Ningdao Fluorosilicone Rubber maintains stable material properties, delivering reliable sealing and protection solutions across industries.

II. Core Features

1.       Superior Oil ResistanceResists degradation from diesel, gasoline, motor oil, kerosene, lubricating oil, olive oil, cooking oil, vegetable oil, essential oils, and transformer oil. Does not swell or deform; maintains stable performance.

2.       Chemical Resistant: Excellent resistance to chemical media such as alcohol, dichloromethane, and silicone oil; suitable for complex chemical environments.

3.       pH无忧Ensures long-term stable operation in acidic and alkaline environments, extending equipment lifespan.

4.       Ultra-Wide Temperature Range: Outstanding high- and low-temperature resistance (from 70°C to 260°C), designed for extreme temperature conditions with no performance degradation.

5.       Import-grade quality, domestic alternativeIndependently developed and manufactured; quality comparable to imported fluorosilicone, with lower costs and more stable supply.

3. Application Scenarios

1.       Aerospace Industry: Aircraft fuel, lubricant seals (O-rings, seal rings, diaphragms, etc.), sensor materials, and integral tank sealing for critical components.

2.       Automotive IndustrySeals, oil seals, diaphragms, tubing, valve liners, etc., ensuring reliability of the engine and transmission system.

3.       PetrochemicalPump and valve seals, as well as oil tank sealing products, resistant to high/low temperatures and corrosion for harsh chemical environments.

4.       Military Industry: Bellows for military aircraft hydraulic systems, specialized seals for vehicles (doors, windows, rear hatches), sensor materials, and more—meeting the stringent requirements of military equipment.

5.       Mechanical, Electrical, and New Energy:

◦         Seals for Home and Automotive Diffusers

◦         New energy battery sealing films and gaskets for enhanced safety and stability.
