Paper Based Industrial Laminates
Paper Hylam, also widely known as Paper Bakelite, Paper Hylam Sheet, Paper Bakelite Sheet, Paper Phenolic Laminates, Phenolic Paper Laminate, Paper Base Laminate, Paper Laminate Sheet, or Paper Laminate Board, is a cost-effective, high-performance thermoset material. It is manufactured by impregnating multiple layers of high-quality cellulose kraft paper with phenolic resin and bonding them under controlled heat and pressure. These Paper Industrial Laminates excel in electrical insulation applications and serve as reliable Electrical Insulation Sheet, Electrical Insulation Board, and Phenolic Insulation Sheet for diverse industrial needs.

Frequently Asked Questions
Q1: What is the difference between Paper Hylam and Fabric Hylam? +
Paper-based grades prioritize superior electrical insulation and lower cost, while fabric-reinforced versions offer higher mechanical strength and wear resistance. Choose paper for pure insulation needs.
Q2: Which grade is best for high-voltage applications? +
Paper P3 Grade provides excellent electrical properties, low moisture absorption, and suitability for high-humidity or tropical conditions — ideal for high-voltage applications.
Q3: Can Paper Phenolic Laminates be used in humid environments? +
Higher grades (P2/P3) perform well with low water absorption, but proper sealing or design considerations are recommended for prolonged exposure.
Q4: What thicknesses and sizes are available? +
Standard thicknesses range from 0.5 mm to 50+ mm. Common sheet sizes include 1220 × 1220 mm and 1220 × 2440 mm; custom sizes and fabrication are available on request.
Q5: Are these materials flame retardant? +
Yes, FR grades (e.g., FR-1/FR-2) meet UL 94 standards for enhanced fire safety in electrical applications.
Q6: Do you provide custom machined parts? +
Yes, as a full-service Paper Laminate Manufacturer, we offer CNC machining, punching, and custom components tailored to your drawings and specifications.
Q7: What standards do your Paper Hylam Sheets comply with? +
Our products comply with IS 2036, IEC 60893, NEMA LI-1, and other relevant industry standards, emphasizing safety, reliability, and value.
Q8: What is the continuous service temperature for Paper Hylam? +
Continuous service up to 90–130°C depending on the grade, classified as Class E or Class B insulation.
