Standard configurations highly specified across major infrastructure networks in Metro Manila, Cebu, and Davao.
The demand for high-performance elastomeric NBR/PVC rubber foam sheets in the Philippines is experiencing unprecedented growth. Driven by robust national initiatives such as the "Build Better More" infrastructure campaign, the expansion of global business process outsourcing (BPO) hubs in Metro Manila, and the rise of agro-industrial cold chains in Visayas and Mindanao, modern Philippine architecture requires superior thermal insulation to cope with complex tropical climate challenges.
Our rubber foam insulation sheets and tubes are engineered from premium Nitrile Butadiene Rubber (NBR) and Polyvinyl Chloride (PVC) co-polymer matrices. This chemical composition provides high flexibility, minimal thermal degradation, and superior fire resistance.

| Water Vapor Permeability (Resistance Factor) | ASTM E96 / BS EN 12086 | μ ≥ 10,000 (Built-in Vapor Barrier) |
| Fire Performance & Flammability | BS 476 Part 6 & 7 / UL 94 | Class 0 (BS 476) / Class V-0, HF-1 (UL 94) |
| Density Range | ASTM D1622 | 40 – 55 kg/m³ (Even cellular distribution) |
| Operating Temperature Limits | ASTM C411 | -40°C to +105°C (Special cryogenic grades down to -200°C) |
| Compressibility & Recovery | ASTM D1056 | ≥ 80% compression resilience rate |
Unlike traditional glass wool or rock wool, Kingflex elastomeric foam sheets feature a closed-cell rate of over 98%. This configuration prevents moisture penetration, ensuring the thermal conductivity remains stable throughout the life of the system.
Designed to comply with high safety requirements. In the event of a fire, the material is self-extinguishing, limits smoke progression, and prevents burning droplets, fulfilling the local fire protection codes of the Bureau of Fire Protection (BFP) Philippines.
The premier choice for large-diameter pipelines, rectangular ventilation ductwork, and flat structural surfaces. The flexible sheets conform easily to complex configurations, reducing seam joints and minimizing potential path points for air infiltration.
Used widely in large commercial facilities like the Manila Metro Line extension project, international airports, commercial shopping malls, high-rise BPO offices, food manufacturing cleanrooms, and chemical plants in Calabarzon and Central Luzon.
Designed for fast installation on metal copper pipes, stainless steel chilled loops, and domestic hot/cold water distribution pipes. The precut cylindrical shape slides over pipes effortlessly before soldering or can be slit longitudinally and sealed with specialized adhesive.
Minimizes thermal transfer, preventing heat gain in chilled water lines, which reduces the electrical load on chillers. Particularly critical for energy saving in the tropical climate of the Philippines.

Designed for heavy industrial refrigeration, low-temperature systems, and color-coded facility identification.
Additional specifications for fire barriers, steam insulation, and corrosion protection across demanding environments.
To support the modernization of the Philippine industrial landscape, Kingflex has established a product development roadmap to meet future specifications.
Minimizes respiratory risk and supports high Indoor Air Quality (IAQ) parameters, complying with ASHRAE standards.
Enhanced formulation designed to improve thermal efficiency under high temperature and humidity environments.
Developing halogen-free, eco-friendly rubber polymers that align with green building mandates.
When selecting a rubber foam manufacturer, local developers and contractors must evaluate both procurement costs and long-term performance benefits. Cheap open-cell alternatives often fail within 24 months in tropical conditions, resulting in energy loss, pipe rust, and water leaks. Specifying Kingflex NBR/PVC closed-cell materials ensures long-term system performance, protecting critical building assets.
