AcoustiPack EXTRA Foam Blocks for Sound Absorbing & Soundproofing
Product Description
The new AcoustiPack™ EXTRA Foam Blocks pack contains 3 acoustic foam blocks. These can be used inside any vacant drive bays to help increase the absorption of unwanted sound energy. Once installed, the foam blocks also help to reduce the internal air volume inside your PC or server case, which in turn may improve airflow velocity and the cooling performance.
The blocks are made from profession-grade dense acoustic foam, which is certified to UL94-HF1 fire rating. The foam is especially effective at absorbing sound at higher-frequency, such as HDD whine, or high-pitch noise from motherboard components. The foam is black, and flexible enough to squeeze into empty 5¼ inch or 3½ inch drive bays to pressure-fit.

Acoustic Materials in AcoustiPack™ EXTRA Blocks
AcoustiPack™ EXTRA Foam Block is precision-cut from a semi-open cell dense but flexible professional-grade polyurethane acoustic foam.
It has a new improved dark gray/black co lour, and is non-shedding and does not crumble or generate dust. This acoustic foam is over 60Kg/m³ - which is unusually dense compared to cheaper alternative noise-reduction foams (most are under 30Kg/m³).
The reasons we choose to source such a high-density acoustic foam are:
1. Higher density improves the sound absorption efficiency at lower frequencies (sub-1kHz) - which is
critically within the range we are seeking to eliminate
2. Higher density materials help to maintain a low flammability performance
3. Higher density foams can withstand being manufactured into thin 'low-reflection' layers for dual-layer
composites
Flammability
The acoustic foam is certified to the highest appropriate UL94 specification for a foamed product (UL94 HF1) for low flammability.
RoHS (Restriction Of the use of certain Hazardous Substances)
Image shows the RoHS compliant logo.
RoHS certified.The foam is RoHS certified. RoHS restricts the use of six substances to within specified limits (Lead Pb, Cadmium Cd, Mercury Hg, Hexavalent Chromium Cr+6, Polybrominated biphenyls PBB and Polybrominated diphenyl ethers PBDEs/PBBEs) within Electrical and Electronic Equipment (often referred to as EEE), thereby contributing to the protection of human health and the environment.
Normal Operating Environment
The foam material is suitable for use in indoor environments within the temperature range -40°C to +100°C, which is in excess of those typically suitable for IT equipment.
