Polypropylene insulation cotton is an efficient thermal insulation material made of polypropylene fiber.

 

Key Features

  • Excellent Thermal Insulation: Effectively reduces building energy consumption and improves energy efficiency.
  • Lightweight & Soft: Lighter and softer than traditional insulation materials, easy to install, and saves labor costs.
  • High Durability: Offers anti-aging performance and long service life, resistant to deformation.
Sample Availability: Custom basis weight samples and third-party testing data available upon request.

Applications

  • Building Insulation: Suitable for exterior walls and roof insulation, significantly improving overall thermal performance.
  • Industrial Equipment: Applied in pipes, tanks, and other equipment for thermal protection and process stability.
  • Apparel Insulation: Soft, breathable, and hydrophobic, ideal as a thermal lining material for garments.

Test Results

Test Basis Weight: 100 gsm

Water Absorption: <1% (ASTM C1104 Standard)

Sample ACME Insulation Competitor Brand
Basis Weight 100 gsm 100 gsm
Thickness 0.08 cm 0.2 cm
Clo. 0.52 0.40
Rcf 0.081 0.062

What are Clo and Rcf?

Clo (Clothing Insulation Value): A unit to measure thermal insulation. 1 Clo ≈ the insulation provided by a typical business suit at 21℃, 50% RH, with still air.

  • Higher Clo = better warmth retention.
  • Reference examples: A light summer outfit (short-sleeve shirt with shorts) typically provides about 0.3–0.4 Clo, while a thick winter down jacket usually falls between 0.5–0.7 Clo.

Rcf (Relative Clo Factor / Resistance per unit thickness): Indicates how effective the insulation is per unit thickness.

  • Helps compare materials of different thickness fairly.
  • Higher Rcf = more efficient insulation per cm thickness.

Interpretation: In the test results above, ACME Insulation shows Clo 0.52 and Rcf 0.081, while the competitor shows Clo 0.40 and Rcf 0.062. → This means ACME's insulation provides both better overall warmth and higher efficiency per thickness.

Technical Information

PP insulation cotton is made of high-quality polypropylene through melt-blown technology and fine structure design, ensuring stable and efficient thermal insulation. Current performance can reach up to Clo. 1.5 level.
