High-density polyethylene (HDPE) is a very commonly used plastic, and it's easy to get if you need sheets of plastic to cut for a project. Plastic itself often comes under fire from various quarters as being not very friendly for the environment, but it's also a handy material that doesn't shatter as easily as glass. There is a way to use plastic that is also environmentally friendly to an extent, and that is using recycled plastic.
Masking tape is often used to protect surfaces during machining processes, sandblasting, and manufacturing applications. Tape forms a barrier that will protect delicate surfaces from contaminants and damage. Some materials that thermal masking tape may need to protect include glass, ceramic, and metal.
Thermal masking tape comes in strip, liquid, and spray formulas. An adhesive that contains thermal properties can be used around high heat applications and flames. This type of tape is much more durable than paper or cellophane tape products.
