Anti Squeak / Anti Rattle Tapes
Squeaks are caused by a phenomenon known as stick-slip. this occurs when two or more surfaces have frictional properties where differences in the static and dynamic friction cause a shuddering movement. When this happens at high frequency, this movement generates a noise or a squeak. Often this is amplified by the resonance of one or other of the components.
To eliminate these squeaks, an isolation material must be employed, to seperate the two surfaces. The choice of material used for this elimination will then be dictated by:
- Flammability and burn rate
- Water absorption
- Abrasion resistance
- Energy absorption capacity
- Ability to bond to low energy surfaces
- Colour fastness to light
Hillcroft North West have products available to cover all aspects of sound abatement; from self adhesive flocking tapes, self adhesive polyurethane bumpers and even UHMW tape (Ultra High Molecular Weight Polythene) a material that will outwear steel.
UHMW PE tape provides a non-stick, low friction surface similar to PTFE tape but with much higher abrasion and puncture resistance. Great for sound dampening. Eliminates squeaks and rattles caused by adjacent parts movement. Tape has a film made of UHMW (ultra high molecular weight) polythene and has .002″ of acrylic adhesive. Thanks to its extremely low coefficient of friction (0.14) UHMW PE tape easily outperforms steel in sliding applications. Its inherent lubricity minimises the smooth, noiseless operation. Color is translucent. Temperature range is -40o F to +225o F. Film (not adhesive) FDA compliant for Food Contact. UHMW-PE Tape can be used where lubrication is not possible because of contamination.
