In cable manufacturing, reliable internal insulation, mechanical reinforcement, and cost-effective layer separation are essential for maintaining electrical integrity and long-term performance. PET Polyester Tape, commonly known as Mylar Tape, is a premium biaxially oriented polyester (BOPET) film tape engineered specifically for the cable industry. Produced from high-grade polyethylene terephthalate (PET) resin, this versatile tape delivers exceptional tensile strength, outstanding dielectric properties, and superior thermal stability — making it the ideal choice for longitudinal or helical wrapping, binding, shielding isolation, and mechanical protection across a wide range of cable constructions.
As a trusted B2B supplier of complete cable materials and technical solutions with over 30 years of global experience, we recognize PET Polyester Tape as a lightweight, high-performance insulation material that enhances cable durability while optimizing production efficiency and total cost of ownership in signal transmission, data, coaxial, control, instrumentation, and power cable applications.
التركيب وعملية التصنيع الهندسية
PET Polyester Tape is manufactured from premium-grade PET resin that undergoes biaxial orientation to create a highly crystalline, dimensionally stable film. Key characteristics include:
- المادة الأساسية: Biaxially oriented polyethylene terephthalate (BOPET) film — known for its high molecular alignment and uniformity.
- Thickness range: Typically 0.025–0.1 mm (custom options available up to 0.25 mm).
- Surface options: Transparent, bright silver/metallized, or matte finishes for visual identification and enhanced reflectivity.
Precision slitting ensures clean edges and tight tolerances, enabling seamless integration into high-speed cable wrapping lines. When required, acrylic or silicone adhesives can be applied for self-adhesive versions, providing strong yet residue-free bonding to conductors, shields, or jackets.
المزايا التقنية الرئيسية وفوائد الأداء
Exceptional Mechanical Reinforcement High tensile strength (typically 150–300 MPa or 80–150 N/cm) combined with excellent elongation ensures reliable binding and wrapping without cracking or stretching during high-speed production. The tape adds structural integrity to cable cores while maintaining overall flexibility.
Superior Electrical Insulation Outstanding dielectric strength (≥5–8 kV/mm, with breakdown voltages up to 5.5 kV or higher depending on thickness) provides effective isolation between conductors, shields, and layers. Low dissipation factor minimizes signal loss in high-frequency applications such as coaxial and RF cables.
Thermal & Environmental Stability
- Melting point: Approximately 250–255°C
- Continuous operating temperature: Up to 150–180°C (Class F rating in many grades)
- Excellent resistance to moisture absorption (<0.5%), UV radiation, chemicals, solvents, humidity, and thermal aging.
Flame-retardant grades are available to meet stringent fire safety requirements in specialty cables.
Processing Efficiency & Clean Application Easy to tear and apply with no residue, the tape features uniform thickness and precision-slit edges that reduce waste and ensure smooth, wrinkle-free wrapping. Its bright silver or transparent appearance aids quality inspection on the production line.
Cost-Effective & Sustainable Lightweight design reduces overall cable weight compared to thicker alternatives, supporting lower material costs and easier installation while remaining fully recyclable.
Primary Applications in Cable Systems
PET Polyester Tape (Mylar Tape) is widely specified for:
- Signal Transmission, Data & Instrumentation Cables: Binding and separation layers to maintain pair geometry and electrical isolation.
- Coaxial & RF Cables: Internal wrapping for dielectric support and shielding isolation.
- Control & Power Cables: Mechanical reinforcement and additional dielectric strength between conductors and shields.
- كابلات متخصصة: Composite constructions requiring smooth, uniform layers for improved flexibility and long-term reliability in industrial, automotive, aerospace, and renewable energy applications.
It excels in longitudinal or helical wrapping where a thin, high-strength insulating barrier is needed without adding significant bulk.
