Ceramic-coated silicone composite tape addresses “fireproofing and insulation,” while two-component sound-absorbing foam addresses “noise and vibration.” Both product lines are manufactured in our own factories, and thickness, width, adhesive backing, and shape can be customized according to drawings and specific requirements.
Ceramic-Coated Silicone Composite Tape
It features an alkali-free glass fiber cloth as its reinforcement, with a liquid silicone rubber capable of ceramicization precisely coated on both sides. It is soft and easy to wrap at room temperature; when exposed to high temperatures of ≥550°C or an open flame, it rapidly sintered into a dense ceramic shell, forming a monolithic protective layer that is fire-resistant, heat-insulating, and electrically insulating. It is widely used for fire-resistant wrapping of cables and electrical circuits.
Comparative Experiment on Burning with an Open Flame
When the same flame gun was used to simultaneously expose two cables to heat, the insulation on the ordinary cable quickly turned black and cracked; the cable wrapped in a ceramicized silicone composite tape self-extinguished after the flame was removed, with the wrapping layer sintering into a hard, ceramicized protective layer, leaving the wiring intact.
Unshielded Cables: Coking
When exposed to fire, the insulation shrinks and chars, causing the circuit to lose its protection.
Composite Belt Protection: Intact
A dense ceramic shell forms at high temperatures, while electrical insulation and mechanical strength are maintained.

SPECIFICATIONS Specifications
Three-Layer Composite Structure · Scientifically Layered
Each layer serves a different function, working together to provide fire resistance, thermal insulation, electrical insulation, and mechanical reinforcement.
Top Layer · Liquid Ceramic Silicone
A special ceramicizable liquid silicone rubber is precisely applied to the surface of the fiberglass fabric. At room temperature, it is flexible and easy to apply; at temperatures of ≥550°C, it rapidly sintered into a dense ceramic shell, blocking the inward transmission of flames and heat.
Middle · Fiberglass Cloth
High-strength alkali-free glass fiber fabric serves as the reinforcing framework, providing excellent tensile strength and dimensional stability, maintaining structural integrity under extreme high temperatures, and preventing tearing and deformation.
Base Layer · Liquid Ceramic Silicone
Ceramic silicone, made from the same material as the top layer, is applied to the back of the fiberglass cloth to enhance overall fire resistance and thermal insulation, and to ensure a tight bond with the substrate during wrapping. With a ceramic coating on both sides, there is no need to distinguish the orientation during installation.
Two-Component Sound-Absorbing Cotton
This acoustic foam features a three-layer structure created by laminating ultra-fine polypropylene (PP) microfibers and polyester (PET) fibers using a melt-blown process: the PP microfibers form a micron-scale pore network that absorbs sound energy, the PET fibers provide resilience and structural support, and the nonwoven outer layer prevents dust shedding. Available in widths up to 1.6 meters and unlimited lengths; can be backed with adhesive and die-cut to shape.
Two-part design · Opens with a single cut
Product Photos: The material can be easily cut to size; it does not burn or explode when exposed to an open flame and self-extinguishes when removed from the flame; its three-layer composite structure is clearly defined, allowing for direct bonding or mold forming.
Easy to Cut
It has a flexible texture and can be easily cut to size; it supports adhesive backing, die-cutting, and waterjet cutting to create various shapes.
The fire goes out on its own
It does not burn or explode when exposed to an open flame and self-extinguishes once the flame is removed, meeting the safety requirements for materials used in vehicles.
Long-lasting bounce
The PET hollow spiral fiber core provides loft and compression resistance, ensuring it does not flatten over time.
THREE-LAYER ACOUSTIC Structure
Three-Layer Composite · Scientific Noise Reduction
PP for sound absorption, PET for support, and nonwoven fabric for protection—each layer is designed to enhance acoustic performance and ensure long-term reliability.
PP Microfiber Layer
Polypropylene ultrafine fibers form an extensive micrometer-scale pore network. When sound waves enter, they cause the fibers to vibrate, converting sound energy into heat through friction; the finer the fibers and the denser the pores, the higher the broadband sound absorption efficiency.
PET Fiber Reinforcement Layer
Coarse-denier and hollow-core spiral PET fibers form the material’s structural framework, providing excellent loft, resilience, and compressive strength. This ensures the product will not collapse or deform over time, while also making it easy to cut and install.
Nonwoven Covering Layer
A nonwoven fabric is applied to the surface to protect the fiber structure and prevent dust from falling off; the breathable design allows sound waves to pass through freely while enhancing surface strength and abrasion resistance, making installation and maintenance easier.
