Product Description

Phenolic Heat-Resistant Fiber (Textolit) | Properties, Types & Applications

Phenolic fiber—commonly known as Textolit or heat-resistant fiber—is a durable thermoset insulation material made from layers of resin-impregnated paper or fabric. It is mainly used in high-temperature and electrical insulation applications and is offered in two major forms: fabric-reinforced (cloth-based) and paper-reinforced (bone-based).

This product is a vital part of modern electrical, mechanical, and thermal systems, available in various forms including sheets, rods, and tubes (bushings).

✅ Key Features of Phenolic Heat-Resistant Fiber

Excellent electrical insulation (strong dielectric properties)
High mechanical strength
Lightweight and thermally stable
Flame-resistant and low flammability
Easy to machine (cutting, drilling, turning)
Available in multiple grades and formats

📌 Types of Phenolic Heat-Resistant Fiber

Type	Reinforcement Material	Key Properties	Use Case Examples
Fabric-Reinforced (Cloth)	Cotton or synthetic cloth	High impact resistance, good pressure strength	Gears, mechanical parts, spacers
Paper-Reinforced (Bone)	Cellulose paper	Excellent dielectric properties, rigid texture	Electrical panels, insulation pads
Fiberglass Sheet (FRP)	Woven fiberglass	Excellent mechanical & electrical resistance	High-voltage environments
Epoxy Glass Fiber (G10/G11)	Fiberglass with epoxy	Outstanding insulation in high humidity	PCB boards, aerospace components

🔧 Technical Specifications

Property	Typical Range
Density	1.35 – 1.45 g/cm³
Thermal Resistance	Up to 150°C
Dielectric Strength (Perpendicular)	25 – 30 kV/mm
Flexural Strength	100 – 150 MPa
Tensile Strength	70 – 120 MPa
Impact Resistance (Izod)	Moderate to High (based on type)
Water Absorption	Low (bone fiber absorbs more than cloth)

🔍 Comparison of Cloth vs. Bone Phenolic Fiber

Property	Fabric-Based (Cloth)	Paper-Based (Bone)
Dielectric Strength	25 kV	30 kV
Tensile Strength	Medium	High
Flexural Strength	Medium	High
Impact Resistance	High	Medium
Compressive Strength	High	Medium
Water Absorption	Low	Moderate

🔄 Applications of Phenolic (Textolit) Fiber

Electrical insulation for transformers, switches, and circuit boards
Thermal shields in industrial furnaces and heating systems

❓ Frequently Asked Questions (FAQs)

Q1: What is the temperature resistance of phenolic fiber?
A: It can withstand up to 150°C, depending on the type and thickness.

Q2: What are the differences between bone and cloth phenolic sheets?
A: Cloth-reinforced types have higher impact and compression resistance, while bone-based types have better dielectric and tensile properties.

Q3: Is phenolic fiber flame-resistant?
A: Yes. It resists ignition and does not release toxic fumes when heated.

Q4: Can I order custom sizes or shapes?
A: Yes. We provide custom fabrication and machining based on your specifications.

Q5: How does phenolic fiber compare with fiberglass?
A: Phenolic is generally better for insulation, while fiberglass offers higher structural rigidity in high-voltage applications.
