Phenolic Plastic Sheets

Phenolic sheets are high-performance thermoset composite materials made by layering cellulose fibers (kraft paper or cotton fabric) saturated with phenolic resin and cured under high pressure and temperature. Renowned for their exceptional fire resistance, mechanical strength, and electrical insulation, these sheets are engineered to replace conventional materials like wood, metal, or plastics in harsh environments.

High-Performance Phenolic Plastic Sheets

 

Phenolic Plastic Sheets are high-performance thermoset composite materials made by layering cellulose fibers, such as kraft paper or cotton fabric, impregnating them with phenolic resin, and curing them under high temperature and pressure. They offer excellent fire resistance, mechanical strength, and electrical insulation, and are designed to replace traditional materials such as wood, metal, or plastic in harsh environments. We offer a variety of thicknesses ranging from 0.3 mm to 50 mm, with a standard size of 1220 x 2440 mm (customizable), and a variety of finishes including glossy, matte, or textured. All products are UL 94 V-0, RoHS, and REACH compliant.

Versatile Industrial Applications

 

Phenolic sheets are specified for a wide range of demanding applications where mechanical and electrical performance is critical. They are extensively used as electrical insulators in transformers, switchgear, and terminal boards due to their high dielectric strength. In manufacturing, their rigidity and dimensional stability make them an ideal material for fabricating jigs, fixtures, wear pads, and structural components. The material's resistance to heat and wear also makes it suitable for creating gears and other mechanical parts.

Frequently Asked Questions (FAQ)

 

Q1: What are the main advantages of using Phenolic Plastic Sheets?
A1: The primary advantages are their excellent combination of high mechanical strength, superior electrical insulation, and inherent flame resistance, making them extremely durable and safe for demanding applications.


Q2: What is the difference between paper-based and cotton-based phenolic?
A2: Paper-based phenolic is generally used for its excellent electrical insulation properties. Cotton-based phenolic has higher mechanical strength and impact resistance, making it better for structural parts and gears.


Q3: Are these sheets easy to machine?
A3: Yes, phenolic sheets can be readily machined, drilled, tapped, and cut using standard equipment, though carbide-tipped tools are recommended due to the material's abrasive nature.


Q4: Do you offer different surface finishes and custom sizes?
A4: Absolutely. We can supply sheets in various finishes (glossy, matte, textured) and provide custom-cut sizes to meet the specific requirements of our wholesale clients.
