1. What is a bakelite sheet and what are its main uses?
Bakelite sheet is a thermosetting phenolic resin laminate widely used for electrical insulation, mechanical components, switchgear panels, and industrial applications due to its high strength and heat resistance.
2. What is the difference between bakelite sheet and glass epoxy (FR4/G10) sheet?
Bakelite sheets are phenolic-based and cost-effective, ideal for low to medium electrical insulation, while glass epoxy sheets like FR4 offer higher mechanical strength, moisture resistance, and are commonly used in PCB and high-performance applications.
3. What are the available sizes, thicknesses, and grades of bakelite sheets in India?
Bakelite sheets are available in thicknesses ranging from 1mm to 100mm, including common variants like 3mm, 6mm, and 10mm, and grades such as paper-based, cotton fabric, and NEMA grades like XX and LE.
4. What is the price of bakelite sheet per kg in India?
The price of bakelite sheets in India varies depending on grade, thickness, and quality, typically ranging from ₹120 to ₹300 per kg. Bulk orders and custom sizes may offer better pricing.
5. Where can I buy bakelite sheets online or near me in Mumbai?
You can buy bakelite sheets from reliable manufacturers and suppliers in Mumbai, especially in industrial hubs like Matunga, offering custom cutting, bulk supply, and quick delivery across India.
6. What are bakelite sheets used for in electrical and industrial applications?
Bakelite sheets are used in transformer insulation, motor winding, electrical panels, switchgear, PCB base materials, and CNC machined components due to their insulating and heat-resistant properties.
7. What is the difference between phenolic sheet and bakelite sheet?
Bakelite sheet is a type of phenolic sheet made using phenol-formaldehyde resin. While all bakelite sheets are phenolic, not all phenolic laminates are bakelite, as they may include fabric or glass reinforcement.
8. Which insulation material is best for transformer and motor winding?
For transformer and motor winding, materials like bakelite sheets, Nomex paper, FR4 sheets, and electrical insulation paper are commonly used depending on temperature resistance and electrical load requirements.
9. Do bakelite sheet manufacturers provide custom cutting and CNC machining?
Yes, leading bakelite sheet manufacturers in India offer custom cutting, CNC machining, and fabrication services to meet specific industrial and OEM requirements.
10. What factors should I consider when choosing a bakelite sheet supplier in India?
Look for quality certifications, material grades, pricing, customization options, delivery capability, and industry experience when selecting a reliable bakelite sheet supplier.
