Mastic Tapes for Insulating and Sealing
There is a mastic for virtually every application.
Mastic comes in tape and roll form and in a variety of thicknesses and operating temperatures.
- Choose thinner mastics for moisture resistance in lower voltages and tight spaces.
- Choose thicker mastics when you need extra padding and durability from sharp edges or heavy vibrations.
- Save time and eliminate the added step of overwrapping when you use pre-laminated vinyl mastic and rubber mastic products.
Even with a lot of information, understanding the pros and cons and picking a tape can be tricky. Let 3M save you time with these application summaries and quick product comparisons to find the right mastic solution for your application.

Mastic Rolls, Pads & Putty
Choose mastic only when you need padding, flexibility and conformability to manipulate the material to fit on or in your application. At 125mils, they are your thickest options – but these tape, pads and putty are versatile and can be cut, stretched, scrunched and rolled to fit in even small spaces. However, you will still have to wrap another material like vinyl over it to contain the mastic and provide jacketing protection.
