Product Description

HEAT RESISTANT PTFE  TAPE

Heat Resistant Adhesive Solution

Our premium PTFE fiberglass tape is engineered for high temperature, non-stick and anti-abrasion industrial applications.

Constructed with woven fiberglass fabric impregnated with PTFE and coated with high-temperature silicone adhesive on one side,
it delivers outstanding heat resistance, release property and wear resistance for diverse processing scenarios.

The PTFE fiberglass substrate brings excellent non-stick performance, enabling the tape to repel sticky residues, glues and adhesives.
It performs well in heat sealing, packaging, food processing, woodworking hot pressing and electrical insulation scenarios.
The silicone adhesive liner guarantees smooth peeling, convenient cutting and easy manual or machine processing. Meanwhile,
the PTFE coating offers excellent chemical resistance, effectively resisting most acids, alkalis and solvents for long term reliable protection.

Key Features
1.Extreme High Temperature Resistance

Maintains stable physical performance within -70°C to 260°C, adapting to continuous high-temperature working environments including heat sealers, vacuum sealers and hot press equipment.
2.Non-Stick & Easy Release

Smooth PTFE surface prevents melting plastics, glues and food materials from sticking; leftover residues can be wiped off effortlessly.
3.Abrasion & Tear Resistance

Reinforced with woven fiberglass base fabric, the tape withstands repeated friction and scraping, not easy to crack under
continuous mechanical contact.
4.Chemical Inertness

Resists most acids, alkalis, oils and chemical solvents, suitable for chemical processing and corrosive working conditions.
5.Electrical Insulation Property

Provides reliable dielectric insulation for electronic wiring, circuit boards and electrical components.
6.Low Friction Surface

Features ultra-low surface friction coefficient, ideal for sliding surfaces, conveyor guides and packaging machinery parts.

Product Application

Key Applications:

1. Packaging & Heat Sealing (Main Application)
Ideal for vacuum sealers, bag-making heat rollers and cutting blades. Its non-stick surface prevents plastic film melt adhesion, simplifies cleaning and extends heater service life with food-grade safety.

2. Heat Transfer & Garment Printing
Perfect for heat press machines and iron pads. It blocks hot ink & glue residue, avoiding pattern sticking and leaving zero residue
after repeated pressing.

3. Lithium Battery New Energy Manufacturing
Used on coating machines and cell heat-seal jigs. It delivers high-temp resistance, insulation and electrolyte corrosion resistance

to raise production yield.

4. Solar PV Industry
Applied to PV laminators and wafer processing rollers. It stops EVA film sticking under continuous high-temperature lamination.

5. PCB & Semiconductor Precision Machining
Suitable for reflow soldering fixtures and FPC hot-press molds, offering reliable insulation and anti-contamination protection

for delicate electronics.

6. High Temp Wire & Electrical Insulation
Wraps automotive & equipment wiring harnesses. It provides stable dielectric insulation and flame retardancy for long-term

circuit safety.

7. Industrial Mold Release & Hot Pressing
Works for injection molds and woodworking heat tools. Smooth release surface avoids material adhesion and cuts

mold cleaning frequency.

8. Food & Anti-Corrosion Processing Equipment
Fit for baking ovens and chemical processing gear. Inert PTFE material resists most acids, alkalis and solvents for

harsh working conditions.
