When it comes to thermal and acoustic insulation, not all materials are created equal. True efficiency depends on three critical factors: fiber diameter, internal structure, and porosity. Transulate™ leverages advanced meltblown fiber insulation technology to optimize all three — resulting in a high-performance solution for demanding applications.

1. What Makes an Insulation Material Truly Efficient?
The performance of any insulation system hinges on how well it can trap air, slow heat transfer, and reduce sound waves.
Fiber diameter determines how much surface area is available to resist heat flow.
Structural integrity maintains loft and prevents collapse under vibration or moisture.
Porosity controls airflow resistance, which is essential for both thermal and acoustic performance.
Transulate™ is engineered with these principles at the core.

2. The Meltblown Matrix: Explained Simply
At the heart of Transulate™ is a dual-fiber meltblown nonwoven:
PP microfibers (~2 μm) — form a dense thermal shield that minimizes conductive and convective heat transfer.
PET structural fibers (~25 μm) — provide mechanical stability and loft, ensuring the insulation maintains thickness over time.
3D porous network (>85% void fraction) — disrupts sound wave propagation and creates a long, complex air path, delivering high acoustic absorption and a powerful thermal break.
This hybrid structure combines the best of both worlds: lightweight flexibility with robust, long-term performance.

3. Why Ultrafine Fibers Matter
Conventional insulation materials — like mineral wool, glass wool, and polyurethane foam — have limitations in fiber uniformity and air control. Transulate™’s ultrafine PP PET insulation offers:
Higher surface area → more contact points to slow heat transfer.
Enhanced air trapping → lower thermal conductivity without increasing bulk.
Improved diffusion → better control over sound wave attenuation.
In short, ultrafine fibers allow superior insulation efficiency at lower thickness and weight, making them ideal for applications where space and mass are critical factors.

4. Formaldehyde-Free + Low VOC = Safe for People & Planet
Unlike traditional insulation that uses formaldehyde-based binders, Transulate™ is formaldehyde-free insulation with low VOC emissions.
Complies with REACH, RoHS, and California Proposition 65 for material safety.
Eliminates health concerns related to off-gassing, especially in confined spaces like automotive cabins, aircraft interiors, and HVAC systems.
Environmentally responsible manufacturing supports sustainable design goals without compromising performance.
