Rubber plastic insulation sheet, a high-quality thermal insulation material, plays a vital role in reducing energy consumption and improving building efficiency. To ensure its optimal performance, it is essential to assess its water vapor permeability, as this property directly affects its service life.
Rubber plastic insulation sheet derives its insulating properties from the tiny air bubbles within its structure. The more abundant these bubbles, the higher the gas content and, consequently, the better the insulation effect. However, when exposed to varying temperature and humidity conditions, water vapor can penetrate the material. This is problematic because water has a higher thermal conductivity than air, leading to a decrease in insulation efficiency and a shorter lifespan. Therefore, the water vapor resistance of thermal insulation materials is a critical factor for long-term durability.
The Labthink C360H Water Vapor Transmission Rate Test System is a specialized instrument designed to accurately measure the water vapor transmission rate of materials like rubber plastic insulation sheet. This instrument is designed and manufactured based on the gravimetric determination method and conforms to the requirements of ASTM E96. This instrument can be used to measure the water vapor transmission rate of barrier materials with high, medium and lower moisture barrier properties with a wide testing range and high testing efficiency. The instrument features Labthink’s patented test chamber design with multiple test dishes. C360H is equipped with precision made test dishes, highly accurate balance, embedded professional software which supports automatic controlling of temperature, humidity and flow rate precisely and guarantees the testing sensitivity and repeatability of the test results. C360H is applicable to determination of water vapor permeability of plastic films, sheeting, paper, packages and other packaging materials in food, pharmaceutical, medical apparatus, building materials and consumer goods, etc.
To evaluate the water vapor permeability of rubber plastic insulation sheet, the ASTM E96 standard is commonly followed. This standard requires a controlled environment with a constant temperature and humidity of (23 ± 1) °C and a relative humidity of (50 ± 3)%. The test involves placing a sample of the insulation sheet within a test chamber, with a desiccant inside to create a 0% humidity environment. The water vapor from the surrounding air then permeates the sample, and the rate of water vapor transmission is measured by regularly weighing the test cup.
By using advanced testing equipment, manufacturers and users of rubber plastic insulation sheet can effectively assess its water vapor permeability, ensuring that it meets the required standards for energy efficiency and long-term durability.
As the demand for functional packaging materials grows, testing methods are evolving to ensure a more comprehensive evaluation of packaging films. Labthink encourages collaboration with packaging industry companies for quality control! Visit the website www.labthink.com to learn more!
