Industrial laminates are typically constructed from multiple layers of fibrous reinforcement that are bonded together with high-quality thermosetting resins. These materials come in various grades and can be utilized across a broad spectrum of applications, including:

• Electrical Transformers
• Gears
• Bearings
• Jigs
• Fixtures
• Thermal Breaks

At Ai, we provide industrial laminates in different grades and sheet forms, all custom-cut to your specifications. Orders placed online before 1:30 PM qualify for next-day delivery! The laminates we offer at Ai include:

Paxolin / Paper

Paper-based laminates, also known as SRBP or synthetic resin-bonded papers, are made from stacked layers of paper saturated with specially formulated synthetic resins. This material is easy to machine, featuring excellent mechanical and electrical properties with good impact strength, making it ideal for various engineering components.

SRBP P1 serves as an economical, low-voltage insulation material, suitable when electrical requirements are moderate. It is available in both brown and black colors.

On the other hand, P3 (kite) exhibits superior electrical insulation properties and is ideal for high-voltage applications.

Overall Applications

• Spacers
• Base plates
• Side plates
• Simple jigs and fixtures

Fabric-based Laminates

Fabric-based laminates, also known as SRBF or synthetic resin-bonded fabric, are renowned for their high strength, high-temperature resistance, and electrical insulation properties. They are manufactured using high-pressure laminating processes with synthetic phenolic resins to create a rigid and wear-resistant product.

Characteristics

• High strength-to-weight ratio and performance.
• Choice of color and surface finishes.
• Outstanding dielectric strength.
• Low thermal conductivity and microwave transparency.
• Resistance to corrosion and water.
• Lower tooling and setup costs.
• Reduced production costs compared to metal fabrication.
• Operating temperature ranges up to 120 degrees Celsius.

SRBF F1

F1, a phenolic cotton laminate, is a fine-weave material that displays exceptional mechanical and chemical properties. The material is machined to precise tolerances.

It exhibits good wear resistance, low water absorption, and excellent dimensional stability, making it suitable for a variety of components, particularly those requiring intricate features with a fine machined finish. It has better electrical strength than the F2 grade.

Applications

• Fine-toothed gears.
• Seal retaining rings.
• Geneva wheels.
• Actuating arms.
• Insulating sleeves.
• Bushes and insulation for low and medium voltages.
