Discover our core range of elastomeric NBR/PVC rubber foam insulation systems, designed to mitigate impact sound transmission, suppress structure-borne vibration, and deliver superior thermal insulation.
Modern building regulations require strict Impact Insulation Class (IIC) and Sound Transmission Class (STC) standards. Sound-absorbing carpet paddings based on micro-cellular NBR/PVC structures act as mechanical decoupling systems. They damp impact energy from footsteps, dropped items, and structural resonance, providing up to 25dB reduction in transmission noise.
The market is shifting from single-function underlayments to multi-barrier systems. By combining closed-cell thermal performance (preventing convective heat transfer) with open-cell acoustic absorption (trapping ambient high-frequency sounds), contemporary elastomeric underlayments decrease overall building energy usage while ensuring sound isolation.
Acoustic systems under carpets must comply with strict green building standards like LEED, BREEAM, and DGNB. Industry pioneers now prioritize chemical formulation stability to prevent off-gassing. Our eco-friendly foam formulations prevent the growth of mold and mildew in humid conditions, maintaining clean indoor air quality.
Traditional foam underlayments break down under high foot traffic, losing their elasticity and sound damping properties. Advanced NBR/PVC synthetic elastomer technology retains over 80% compression resilience over a decade, making it the preferred choice for commercial acoustic installations.
Procuring building components requires deep compliance alignment, technical verification, and reliable delivery. Top-tier EPC contractors, architectural firms, and industrial distributors rely on manufacturers who can guarantee specific physical and structural performance metrics:
| Procurement Parameter | Standard Specification Required | Kingflex Compliance Level |
|---|---|---|

| Thermal Conductivity | ≤ 0.035 W/(m·k) at 0°C | ≤ 0.032 W/(m·k) (Superior thermal barrier) |
| Impact Sound Reduction (IIC) | ≥ 50 dB under typical floorboards | Exceeds 55 dB (With specific carpet structures) |
| Density Range | 35 - 65 kg/m³ | 40 - 55 kg/m³ (Optimized dampening balance) |
| Environmental Traceability | REACH, RoHS, LEED v4 Compliant | Independently tested, certified trace chemicals |
Kingflex Insulation Co., Ltd. operates five large automated assembly lines, delivering an annual production capacity exceeding 600,000 cubic meters. Based in Dacheng, China—a hub for green building materials—our production systems integrate automated mixing, continuous vulcanization, and real-time thickness profiling.
This continuous extrusion process ensures uniform density distribution. Every square meter of sound-absorbing underlayment exhibits consistent cell structural alignment, eliminating physical weak spots that could otherwise lead to premature acoustic degradation.
Our acoustic underlayments and rubber foam products are engineered for specific, high-stress environments.
Used beneath high-traffic carpet tiles in open-plan offices and conference halls to absorb mid-to-high frequency vocal noise, reducing acoustic echo and helping team focus.
Installed in luxury hotels, corridors, and guest suites to control sound transmission between floors, providing guests with quiet spaces that meet strict multi-star ratings.
Used alongside air conditioning ducts, piping systems, and machinery housings to block structural vibrations from transferring to the floor assemblies.
Our black rubber foam insulation sheet rolls provide combined thermal barrier efficiency and vibration damping. Designed with a flexible NBR/PVC matrix, it features a high density of closed cells that limit heat transfer and stop moisture penetration.
Engineered to isolate industrial process lines, plumbing setups, and HVAC piping from thermal gain and moisture buildup. The smooth inner surface helps ensure simple installation on curved layouts.
Our facility employs 8 full-time R&D engineers to continuously refine acoustic absorption properties, flexibility profiles, and thermal stability in hot or cold environments.
Our insulation materials have been used in airports, district energy loops, and commercial buildings worldwide.
