Performance Requirements of Anti-Squeak, -Itch, -Rattle Fiber Tape
|Publication Date:||1 October 2018|
This specification covers the material properties and durability requirements of a flocked fabric, felt, or nonwoven sound abatement tape. These tapes are used for interior sound abatement applications where two similar or dissimilar substrate materials come into contact, causing a rubbing, chafing, itching, chattering, rattling or squeaking noise. Typical areas of application are between interior trim parts, instrument panel components and other areas, depending on the origin of undesired sound. In most cases, the tape becomes trapped between two surfaces.
Type I Material; is flocked fabric or a (felt), coated with a permanent, acrylic, pressure-sensitive adhesive. Typically, the Type I Tape fibers are nylon; however, other polymers, or blends of polymers, can be used. The backing can be a woven blend of polyester and cotton or other polymers.
Type IA Material. Is NOT exposed to ultraviolet (UV) light.
Type IB Tape. Is exposed to UV; therefore, it must exhibit weathering resistance. Type IB Tape may be used to line the bottom of coin holders or storage bins in direct exposure locations. 1.1.2 Type II Material; is a nonwoven tape coated with a permanent, acrylic, pressure-sensitive adhesive. The nonwoven fiber can be various polymers, typically polyester or polyurethane. Type II Material is a lower-cost, lower-performance alternative to Type I Material used in less demanding applications.
If there is no type callout on the drawing, the construction is assumed to be Type IA Material.
