Bronze PTFE Seal by Polypac: Durable, Low-Friction Sealing Solutions

Bronze PTFE Seal by Polypac — High-Performance Sealing for Demanding Conditions

Overview

Polypac's Bronze PTFE Seal combines the low-friction, wide-temperature benefits of PTFE with bronze-filled reinforcement to deliver seals that resist wear, extrusion, and deformation. Designed for hydraulic systems, reciprocating and rotary shafts, and oil sealing applications, our bronze-filled PTFE products provide long service life and reliable performance under high load and contaminated environments.

Material Advantages

Bronze-filled PTFE offers enhanced mechanical strength, improved thermal conductivity, and superior anti-galling properties compared with virgin PTFE. The bronze filler increases load capacity and dimensional stability while retaining the chemical resistance and low coefficient of friction that make PTFE ideal for sealing. These properties reduce stick-slip and torque in dynamic applications.

Key Applications

Typical uses for the Bronze PTFE Seal include hydraulic cylinders, pneumatic actuators, oil pumps, industrial valves, and rotating equipment. Polypac seals are especially suited for heavy-duty hydraulics, harsh chemical exposure, elevated temperatures, and situations where low maintenance and long intervals between service are mandatory.

Customization & Manufacturing

Founded in 2008, Polypac manufactures bronze-filled PTFE seals with precision machining and molding across a modern 10,000+ m² facility. We provide custom dimensions, compound formulations, and tailored profiles to meet OEM and retrofit needs. Our in-house development supports rapid prototyping and scale production to exacting tolerances.

Quality Assurance & Testing

Polypac maintains rigorous testing protocols, using advanced equipment to validate wear resistance, dimensional stability, and chemical compatibility. Long-term partnerships with universities and research institutions support continuous material improvement and performance verification for demanding working conditions.

Why Choose Polypac?

As a leading seal manufacturer and oil seal supplier, Polypac blends technical expertise with manufacturing scale to deliver Bronze PTFE Seal solutions that optimize uptime and reduce lifecycle cost.

FAQ:

How can I prevent seal damage during installation?

Use Tools: Always use dedicated installation tools (e.g., picks, cones, guides). Lubricate: Always lubricate the seal and the contact surface. Protect Sharp Edges: Cover sharp threads and edges with tape or use an installation sleeve. Check the Groove: Ensure the installation groove is clean, deburred, and undamaged.

What is the difference between a static seal and a dynamic seal?

A Static Seal is used between two surfaces that do not move relative to each other (e.g., pipe flanges, end caps). O-rings and gaskets are common static seals. A Dynamic Seal is used between surfaces that do move (e.g., piston and cylinder, rotating shaft). Rod seals, piston seals, and rotary shaft seals are designed for this purpose.

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.
