Product Details
DRK311W Derek Weighing Method Water Vapor Permeability Tester Wetted Cup Weighing Method Testing Principle, Equipment * * *, Efficient, Intelligent WVTR * * Testing System, Suitable for Measuring Water Vapor Permeability of Various Materials in Plastic Film, Composite Film, Medical, Construction, and Other Fields. By measuring the water vapor transmittance, the technical indicators of products such as packaging materials can be controlled and adjusted. The principle of using the moisture permeable cup weighing method is to form a specific humidity difference on both sides of the sample at a certain temperature. Water vapor passes through the sample in the moisture permeable cup and enters the dry side. By measuring the change in weight of the moisture permeable cup over time, parameters such as water vapor transmittance of the sample are obtained.

DRK311W Derek Weighing Method Water Vapor Permeability Tester Wetted Cup Weighing Method Testing Principle, Product Application:
1. Basic application:
[Film] Test the water vapor permeability of various plastic films, plastic composite films, paper plastic composite films, geotextile films, co extruded films, aluminum plated films, aluminum foils, aluminum foil composite films, waterproof and breathable films and other membrane materials.
Test the water vapor transmittance of various engineering plastics, rubber, building materials, and other sheet materials. Such as PP sheets, PVC sheets, PVDC sheets, etc.
[Textiles] Used for testing the water vapor permeability of materials such as textiles and non-woven fabrics, such as waterproof and breathable fabrics, diaper non-woven fabrics, and non-woven fabrics for sanitary products.
[Paper and Board] It is applicable to the water vapor transmission test of paper and board, such as cigarette package Aluminium foil, Tetra Pak sheet, etc.
2. Extended Applications
【 Pouring Cup Method Test 】 Place thin film, sheet material, and protective material samples in a moisture permeable cup. The upper surface of the sample is covered with distilled water, and the lower surface is in a certain humidity environment, creating a certain humidity difference on both sides of the sample. Distilled water enters the environment through the sample, and the water vapor transmission rate is obtained by measuring the weight change of the moisture permeable cup over time (note: it is necessary to purchase the pouring cup method moisture permeable cup).
[Artificial skin] Artificial skin needs a certain degree of water permeability to * * * have good respiratory performance after being implanted into humans or animals. This system can be used to test the moisture permeability of Artificial skin.
[Cosmetics] Test of moisturizing properties of cosmetics (such as facial mask and wound dressing)
[Medical supplies and accessories] Water vapor permeability test of medical supplies and accessories, such as plaster patches, sterile wound protection films, beauty facial mask, * * * patches and other materials.
Water vapor transmittance test of solar panels
Water vapor transmittance test of liquid crystal display film. (such as mobile phones, computers, TV screens)
【 Paint film 】 Test the water resistance of various paint films.
[Biodegradable Film] Water resistance testing of various biodegradable films, such as starch based packaging films.
Note: Due to technological progress, the information is subject to change without prior notice. The actual product in the future shall prevail.
