Test Principle
Firstly submerge the specimen in the water in the vacuum chamber, and then evacuate the vacuum chamber to form differential
pressure between the inside and outside of specimen. The seal property can be obtained by observing the steady progression of
bubbles from the specimen or observing how the specimen expands and restores to its original shape after vacuum release.

 Product introduction

GBDA-180W The Compost Degradation Tester is based on the gravimetric method for

measuring carbon dioxide emissions. It is a professional use of small reactors to determine the final biodegradability of test materials. It is suitable for the biodegradability analysis of degradable plastics and bio-based materials such as lunch box garbage, waste ground film, plastics containing plasticizers and pigment additives, etc

Product introduction

This product is based on the test principle of cup method water vapor transmission, and is designed and manufactured according to ASTM E96, GB/T 1037 standards, and provides a wide range and high efficiency water vapor transmission rate detection for low, medium and high water vapor barrier materials. test.

It is suitable for the water vapor transmission performance test of films, sheets, paper, fabrics, non-woven fabrics and related materials in the fields of food, medicine, medical equipment, daily chemicals, etc.

The HP-D1 Automatic Torque Tester HP-D1 is innovated to test cap torque for detecting sealing performance of packaging containers, such as plastic bottles, liquid boxes, cans, etc.

GX-C2 Rub Tester is suitable for testing the abrasion resistance of printing ink layer of printed matter, the abrasion resistance of PS plate photosensitive layer and the abrasion resistance of surface coating of related products. It can effectively analyze the problems of poor rub resistance of printed matter, peeling of ink layer film, low printing endurance of PS version and poor coating hardness of other products.
