Features
Ultra-Low Friction Surface
Provides a very low coefficient of friction (0.04–0.1), ideal for sliding, release, and anti-stick applications.
Excellent High Temperature Resistance
Operates continuously from -180°C to 260°C without deformation or performance loss.
Outstanding Chemical Resistance
Resistant to almost all industrial chemicals including strong acids, alkalis, and organic solvents.
Superior Electrical Insulation
High dielectric strength ensures safe insulation in high-voltage and electronic applications.
Non-Stick & Anti-Adhesion Properties
Prevents material adhesion, making it suitable for release liners and mold surfaces.

Strategic Applications: Lithium Battery Wrapping & Chemical Sealing
STK's 0.025mm pure PTFE film is engineered for industries where standard tapes fail. As an ultra-thin, high-performance solution, it has become a preferred choice for:
Lithium Battery Component Wrapping: In the rapidly evolving EV and energy storage sectors, our $0.025\text{mm}$ PTFE tape provides critical dielectric insulation. Its ultra-thin profile allows for high-density cell packing, while its thermal stability ensures safety during high-discharge cycles. It is highly resistant to electrolytes, ensuring long-term integrity within the battery cell.
Industrial Chemical Sealing: For the chemical processing industry, this tape serves as an impenetrable barrier. The Pure Teflon backing is chemically inert, making it ideal for sealing gaskets, lining pipes, or protecting sensors exposed to aggressive media. Its Low Friction surface also prevents material buildup and facilitates smooth mechanical movements in automated valve systems.
