The Ancor electrical insulation I used for an industrial project was great. According to my experience, it provided excellent protection against electrical current and heat. The industrial and scientific grade materials used in the insulation made it extremely durable... It was also easy to install and removed the risk of any accidents with its high-quality insulation. The only downside was THAT the price was a bit higher than other brands, but considering the quality, it was worth it. Overall, I recommend this product for industrial and scientific purposes..
