Cleanroom vinyl tape has a plastic core so that it can be used in a cleanroom environment. This product is your traditional colored vinyl tape - just not the traditional cardboard core. Tape Solutions provides many clean room contractors, construction, labs, and semiconductor facilities with this product. It is of good quality, can be written on, is very conformable, and abrasion resistant. It is available in a variety of colors and sizes. We stock the most popular 2" white, but for a 1 case minimum, we can order any width and from an assortment of colors. Call us if you need something you don't see here.
