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.
