NBR FOAM TAPE
NBR foam tape stands for nitrile-butadiene rubber foam tape, also called as PVC foam tape. Thermoplastic elastomer is also called artificial rubber or synthetic rubber. Its products not only have the high elasticity, aging resistance, oil resistance of traditional cross-linked vulcanized rubber, but also have the characteristics of common plastic processing convenience, processing mode wide. The nitrile rubber tape can be produced by injection molding, extrusion, blow molding and other processing methods. Moreover, all products meet the RoHS environmental requirements. Furthermore, we can either provide jumbo rolls, or die cutting pieces. The width can be from 10mm to 1600mm, the length can be from 100mm to 2000mm.

Process of NBR Foam Tape Production
NO.1
First, closed cell nitrile -butadiene rubber foam products are mainly produced by Injection molding, extrusion, blow molding and other processing methods. PVC/NBR is a flexible modification material.

NO.2
Second, we coat single sided or double-sided high adhesion of pressure sensitive glue.

NO.3
Third we laminate the white silicon paper liner on which.

NO.4
Finally, we use our lathe slitting machines to cut the jumbo rolls to different standard or non-standard width and length of small rolls. Meanwhile, we can also cut them to different shapes of die cutting pieces.

FAQ of NBR Foam Tape

What is NBR foam tape?
NBR foam tape, or Nitrile Butadiene Rubber foam tape, is an adhesive tape crafted from NBR foam, a closed-cell synthetic rubber. NBR foam tape is made of nitrile -butadiene rubber material and adhesive, with paper liner. Renowned for its durability, flexibility, and resistance to environmental factors, it excels in sealing, cushioning, and insulating applications. With a pressure-sensitive adhesive on one or both sides, it adheres to diverse surfaces like metal, plastic, and wood. The closed-cell structure of NBR foam repels moisture, making it suitable for outdoor and high-humidity settings, while its resistance to temperature extremes and chemicals enhances its versatility. NBR foam tape finds utility across industries, including automotive, construction, electronics, HVAC, offering solutions in gasketing, weather sealing, and vibration damping.

01
