Industrial Sealing Grade
& Thermal Resilience

Engineering a leak-proof future for critical industrial infrastructure.

Our heat resistant gasket series represents the pinnacle of the rubber and plastic components manufacturing sector. By integrating a high-performance PTFE filler with robust metal windings, we provide a solution that defies the standard limitations of thermal expansion and chemical degradation. This architecture ensures a hermetic seal even under extreme pressure fluctuations.

The technical advantage lies in the universal chemical inertness of Polytetrafluoroethylene, which prevents degradation when exposed to aggressive acids and bases. Coupled with precision engineering and strict adherence to international standards like ASME and DIN, our gaskets significantly reduce unplanned downtime and operational risks in heavy industrial piping.

Frequently Asked
Questions

Expert answers to common technical and commercial inquiries.

01

Why choose PTFE fillers for a heat resistant gasket?

PTFE is chosen for its extraordinary chemical resistance and stability across a wide temperature spectrum. It prevents sticking to flanges and resists aggressive solvents used in rubber and plastic manufacturing.

02

Can these gaskets handle extreme high-pressure systems?

Yes, the spiral-wound metal structure provides the radial strength needed to withstand high internal pressures, while the PTFE ensures a gas-tight and liquid-tight seal.

03

What is the difference between SS304 and SS316L winding?

SS304 is suitable for general corrosion resistance. SS316L contains molybdenum, offering superior resistance to chlorides and marine environments, making it ideal for petrochemical use.

04

Are your gaskets compliant with international standards?

Absolutely. Our production lines follow ASME B16.20, DIN, and JIS standards to ensure seamless integration into existing global piping systems.

05

What is the operating temperature limit for PTFE fillers?

Typically, our PTFE fillers can operate effectively from -200°C up to +260°C, depending on the specific pressure and grade of the polymer used.

06

Do you offer customized dimensions for rubber part manufacturing?

Yes, we offer fully customizable diameters, thicknesses, and material combinations to meet the exact technical specifications of your industrial application.
