Product Description
A non-hardening, polymer-modified putty applied at contact points between the indoor AC unit and wall/mounting structure. It damps compressor and fan vibrations, blocks airborne noise paths, and seals gaps around pipes and brackets.
Features
Low noise
Loss factor ≥0.15 effectively converts mechanical vibration (10–80 Hz) into heat-reducing structure-borne noise by up to 60%.
Flexibility
Remains soft and pliable across –40°C to +90°C; no shrinkage, hardening, or loss of adhesion after years of thermal cycling.
Airtight & Pest-Resistant Seal
Conforms to irregular gaps around refrigerant lines and wall penetrations-blocks air leakage, dust, moisture, and insect ingress.
Why Choose Us
Designed for HVAC
Our putty is formulated specifically for indoor AC vibration profiles-validated on compressors operating at 10–80 Hz, unlike generic construction sealants.
Performance
Damping loss factor ≥0.15 (ASTM E756); passes 1,000-hour thermal cycling test with no adhesion loss or hardening.
Consistent Quality
In-house rubber compounding + automated extrusion ensures uniform viscosity and sealing performance-critical for high-volume assembly lines.
Global Partners
Supplied to Tier-1 and Tier-2 AC manufacturers in Germany, Japan, UAE, and Mexico since 2014-with annual volume contracts renewed for 5+ years.

FAQ
Does it adhere to oily copper tubing?
Yes-light oil from pre-charged lines does not affect adhesion. Wipe off excess oil for best results.
Can it be used outdoors?
No-it's designed for indoor unit sealing only. Prolonged UV or rain exposure will degrade performance.
Is it fire-rated?
No. This is not a firestop material. Use only for acoustic, thermal, and moisture sealing-not fire containment.
How much putty per unit?
Typically 150–300g, depending on gap size and number of penetrations. We provide usage guides by model type.
Does it support mold growth in humid climates?
No-formulation contains no organic nutrients and passes anti-fungal testing (ASTM G21).
