What is Air Permeability? Air Permeability is a resistance of fabrics (woven, knitted and non woven textile materials) to the passage of air under constant pre-set air pressure. Air permeability is an important property of some textile materials. The air permeability is mainly dependent upon fabric's weight and construction (thickness and porosity). Labthink TQD-G1 Air Permeability Tester is professionally applicable to the determination of air permeability of decorating materials used in cars, e.g. polyurethane, expanded plastics, PVC, leather, textiles, non-woven and other materials. TQD-G1 Air Permeability Tester conforms to the multiple international standards: ISO 4638 - Polymeric materials, cellular flexible -- Determination of air flow permeability ISO 5636 - Paper and board -- Determination of air permeance and air resistance ISO 9237 - Textiles -- Determination of the permeability of fabrics to air ASTM D737 - Standard Test Method for Air Permeability of...

XLW (PC) packaging seal strength tester is professionally applicable to the determination of force properties of various flexible packaging materials, with high precision (better than 0.5% of reading value) and multiple test ranges. This instrument conforms to various national and international standards as follows: ASTM F88 - Standard Test Method for Seal Strength of Flexible Barrier Materials Part examples for the Packaging Seal Strength Tester Basic Applications: Heat Seal Strength Test, Tensile Property, 90 & 180 Degree Peel Test, Tear Resistance Test and etc. Packaging Seal Stength Test Principle: The pre-conditioned specimen is mounted between two grips, which move in relative direction during the test. The signals of force and displacement changes are separately recorded by the load cell fixed on the driven grip and embedded displacement transducer. The tensile strength, tear strength and elongation rate can be obtained by further calculation. View the v...

In order to maintain the sterility of a packaged product until it reaches its point of end use, Manufacturers must demonstrate that, under the rigors of distribution, storage, handling, and aging, the sterile package integrity is maintained at least for the claimed shelf life of the food or medical device or product. The growth of these barrier packages and retort pouch use is a powerful driving force behind the need to define, standardize and institute critical package integrity tests. A number of physical tests are commonly used for Packages integrity, including: Visual inspection method - "eyeballing" the pouch for problem Internal pressure method (bubble testing) Vacuum leak method, in which the package is submerged in water inside a vacuum chamber and escaping bubbles are observed Trace gas detection, where the package is pressurized with a gas other than air and then examined for escaping gas with a gas leak detector. Pressure (or vacuum) decay test, which i...

W3/030 Water Vapor Permeation Analyzer is for the water vapor permeation rate measurement of plastic films, laminated films, sheets as well as various materials used in medical and construction industries. Through water vapor permeation rate testing, the demands for control and adjust technical indexes and satisfy. This instrument confroms to the followting standards: ASTM E96: Standard Test Methods for Water Vapor Transmission of Materials ASTM D1653: Standard Test Methods for Water Vapor Transmission of Organic Coating Films ISO 2528: Sheet materials -- Determination of water vapour transmission rate -- Gravimetric (dish) method TAPPI T464: Water Vapor Transmission Rate of Paper and Paperboard at High Temperature and Humidity Water Vapor Permeation Analyzer Principle A specific humidity difference is formed among the two sides of the specimen under a certain temperature. The water vapor permeates through the specimen and into the dry side. By measuring the weig...

Business Challenge Lithium-ion batteries have one of the best energy-to-weight ratios, no memory effect, and a slow loss of charge when not in use. This makes them one of the most popular types of batteries for portable consumer electronics in today’s marketplace. Lithium-ion batteries can be found in cameras, laptops, power tools, toys and more. However, as recent well-publicized recalls demonstrate, they can pose a risk of fire and overheating. In addition, they can suffer from a reduced lifespan if not properly treated. As a result, new and stricter requirements are being implemented globally to address potential hazards, leaving manufacturers and purchasers of products containing lithium-ion batteries to meet increasing requirements and overcome safety concerns. Lithium Ion Battery Separators A Lithium Ion battery Separator is a permeable membrane placed between the anode and cathode of a battery. The main function of a separator is to keep the positive and negative electr...

Abstract: weighing method is the basic testing method for water vapor transmission rate measurement. After realizing automatic testing of water method, Labthink has made a series of innovative improvements on weighing method water vapor transmission rate tester with higher testing efficiency and better capability for extension. Thus, customized demands for desiccant method testing and inverted water method testing, as well as testing demands for special samples can be met. Keywords: water vapor transmission rate , WVTR , weighing method , testing efficiency , inverted water method Weighing method has long been the basic testing method for water vapor transmission rate testing with the widest applications, which can be subcategorized into desiccant method and water method, etc. The method needs manual operation in its early stage to accomplish the testing; yet, the relevant instruments are low in automation. Since high efficiency and multi-function are the trend for instrumental devel...
