Description
Hi-Tech Polymers supplies SS-filled PTFE in sheet, rod, and tube form and machines finished components directly from raw stock using our in-house CNC turning centres, VMCs, and precision turning equipment — delivering ready-to-install parts as per customer drawings.
Our in-house machining facility — equipped with CNC turning centres, VMCs, conventional lathes, drilling and tapping machines, and surface grinding — processes SS-filled PTFE from raw stock directly to finished components as per your drawings. We machine to tight tolerances (routinely ±0.05 mm and better) with full dimensional inspection.
Key Properties
- Filler Content: 15–25% 316L/304 stainless steel powder.
- Compressive Strength: Very high, comparable to bronze-filled PTFE.
- Hardness: High, significantly better than Virgin PTFE.
- Wear Resistance: Excellent for high-load, low-speed sliding.
- Chemical Resistance: Excellent, with corrosion-resistant stainless steel filler.
- Friction: Low, retaining PTFE’s self-lubricating properties.
- Thermal Conductivity: Good heat dissipation compared to Virgin PTFE.
- Operating Temperature: -200°C to +260°C continuous.
- Moisture Resistance: Excellent resistance to moisture and chemical attack
Typical Applications
- Chemical process valves and pumps handling aggressive media
- Pharmaceutical processing equipment (where bronze contamination is prohibited)
- Food and beverage machinery requiring corrosion-safe components
- High-purity fluid handling systems
- Sealing elements in oxidising chemical environments
