## Overview

APT Insulating Tape is a premium high-temperature glass fabric tape designed for demanding electrical insulation tasks. Rated for continuous use up to 260°C and UL Listed for Class 'H' insulation, it features a robust 7mm thick glass cloth backing combined with a high-adhesion Duroplast adhesive. Ideal for powder coating, sandblasting, and electrical coil insulation, this tape delivers clean removal without residue, exceptional mechanical strength, and corrosion resistance—perfect for professionals who demand durability and safety in high-heat industrial environments.

## Description

Description: This tape shows excellent dielectric insulation properties and high heat resistance, widely used for electrical insulation for electrical equipment in the field of petroleum drilling, such as motors. PRODUCTION APPLICATIONS Used for electrical and induction furnace power supply line insulation, reinsulation and repair of coils on mining machinery and securing high temperatures, non-PSA insulation in high temperature areas. Features of Glass Cloth Tape High mechanical strength and resistance to high temperature ensure excellent performance, Duroplast adhesive provides increased bond once applied in areas with high ambient temperatures. The thermoplastic adhesive ensures increased temperature performance. The glass fabric back provides mechanical protection that lasts longer and improves safety. The glass cloth will not shrink or rot, providing increased reliability and safety. Wide Applications Heat stable insulation for oven and oven control, flame retardant, high temperature duct sealing, busbar insulation, coil insulation, slot insulation and edge binding. Nominal values: Beam thickness: 5 mm, Total thickness: 7 mm, Adhesion to steel, 100 g, Tensile strength: 81.6 kg, Elongation: 5%, Dielectric strength: 3000 V, Operating temperature range: -73°C to 200°C.

Review: This glass cloth tape is exactly what was needed for a project with high heat requirements. The adhesive is very strong, and the fiberglass backing provides excellent durability and resistance to tearing. It held up perfectly under high temperatures without cracking, and the adhesion remained solid. This tape is a great choice for electrical work in engines, around heat sources, or for other applications where regular electrical tape would fail.
Review: Excellent product. Do not rip, thick and very good adherence. I wish the label would stay on the product instead of being part of the plastic wrapping. This would help for when I need it again to buy it again. :) Not sure long term - will have to update the review if needed.

### ⭐⭐⭐⭐ Review
*by N***P on 15 May 2025*

Seems to be good quality tape, as advertised. I used it to repair a shaded-pole motor, where I needed to cut the existing tape in order to remove and replace a thermal fuse. The replacement tape looks and feels as good as the original. My only concern is that the tape does not feel as 'sticky' as suggested; but it is holding and working well after several days of use. For anyone interested, a "flame test" shows that the tape will burn - probably the adhesives - but the glass cloth stays in place after the flame extinguishes itself. This is well beyond the temperature spec for the tape though -
