Abrasion Resistant Seal Solutions by Polypac

About Polypac

Polypac is a scientific and technical hydraulic seal manufacturer and oil seal supplier specializing in seal production, sealing material development, and customized sealing solutions for special working conditions. Founded in 2008, our custom rubber ring and O-ring factory spans over 10,000 m² with 8,000 m² of production space. We began with filled PTFE seals and expanded to NBR, FKM, silicone, EPDM and FFKM O-rings to meet varied application demands.

Why Choose Our Abrasion Resistant Seal

An Abrasion Resistant Seal from Polypac minimizes wear at friction interfaces, delivering longer operating life and lower downtime. Our solutions reduce friction, resist extrusion and maintain sealing integrity under high-speed reciprocation, heavy loads and particulate-contaminated fluids. Choosing an abrasion resistant seal means fewer replacements, lower lifetime costs and more reliable hydraulic performance.

Materials & Customization

We design abrasion resistant seals using advanced filled PTFE formulations (bronze, carbon, graphite, MoS₂, glass) and engineered elastomers. Material selection is tailored by operating temperature, media compatibility and mechanical load. Polypac offers custom sizes, compound blends and molded or machined geometries to suit cylinders, pumps, shafts and rotary components.

Applications & Performance

Polypac abrasion resistant seals serve mobile hydraulics, industrial presses, construction and mining equipment, marine systems and high-cycle automation. They excel where abrasive particles, high sliding speeds or aggressive pressures threaten standard seals—maintaining tight sealing, low friction and consistent performance in harsh conditions.

Quality, Testing & Research

Our production and testing equipment are among the most advanced in the industry. We maintain long-term collaborations with universities and research institutions for material innovation and performance validation. Every seal undergoes rigorous dimensional, wear and compatibility testing to ensure field-proven reliability.

FAQ:

How do I choose the right material for my sealing application?

Material selection depends on four key factors: Media: What fluid or gas will the seal contact? (e.g., petroleum oil, water, chemicals, steam) Temperature: What is the minimum and maximum operating temperature? Pressure: What is the system's operating pressure? Are there pressure spikes? Application: Is it a static, dynamic, or rotary seal? Example: NBR (Buna-N) is excellent for standard hydraulic oil, while FKM (Viton®) is needed for high temperatures or aggressive chemicals.

Why did my O-ring fail prematurely?

Common causes of O-ring failure include: Chemical Incompatibility: Swelling, softening, or cracking due to fluid exposure. Improper Sizing: Using an incorrect size leads to over-compression or inadequate sealing force. Abrasion: Wear and tear from rough surface finishes or contaminated fluid. Extrusion: The seal is forced into the gap between metal parts under high pressure. Installation Damage: Nicks, cuts, or twists during assembly.

What is the purpose of the metal spring in a rotary shaft seal?

The garter spring in a shaft seal (e.g., FSKR, SPGO types) provides a constant radial force on the sealing lip. This ensures consistent contact with the rotating shaft, compensating for minor wear, eccentricity, and vibration to prevent lubricant leakage.

When should I use a spring-energized seal instead of a standard elastomeric seal?

Consider a spring-energized seal (e.g., GSF, SPN types) for demanding applications involving: Extreme Temperatures (below -30°C or above +200°C) Aggressive Chemicals that elastomers can't handle Very Low Leakage or "Zero Leakage" requirements Poor Lubricity or dry running conditions The internal spring maintains constant sealing force, compensating for wear and system variables.
