Air Permeability Tester

Air Permeability is the resistance of fabrics (woven, knitted and non woven textile materials) to the passage of air under constant preset 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).

Fogging Testing

Materials used in vehicles, such as plastics, fabrics, rubber or leathers, will evaporate under high temperatures and condense on the windshield and create a fog, which causes dangerous driving conditions. Fogging test is right to measure fogging characteristics of these automotive interiors as well as HID lamps.

Friction / COF Tester

Friction tester is a kind of testing equipment which is used to measure coefficient of friction (COF) for materials. Basically, there are two kinds of coefficients: static coefficient of friction and kinetic coefficient of friction. Coefficient of friction testing is widely valued for its important role in the processes of production, transportation and marketing.

Gas Permeability Tester

Gas permeability is the ability of a barrier material to allow gases (O2, N2, CO2 etc.) to permeate through it in a specific time. Gas permeability may vary with temperature, humidity, pressure and speicmen thickness.

Heat Seal Tester

Heat seal test is to determine the suitable sealing parameters (sealing temperature, dwell time and pressure) for materials. ASTM F2029 is the standard practice for making heat seals for the determination of the heat sealability of flexible webs as measured by seal strength.

Hot Tack Testing

Hot tack is the strength of heat seals formed between thermoplastic surfaces of flexible webs, immediately after the seal has been made and before it cools to room temperature. Hot Tack test makes it possible to determine the seal strength and appropriate sealing parameters directly after the heat sealing process.

Impact Testing

Impact test is to measure the ability of materials to resist high-rate impact. Impact resistance can be obtained by calculating the amount of energy that causes test specimen failure. In general, there are two kinds of testers for impact resistance: free-falling dart impact tester and pendulum impact tester,conforming to different international standards.

Leak Testing

Leak test aims to examine the sealing quality and integrity of a package, especially when the package is exposed to a pressure differential. The analysis for package leakage is meaningful for prolonging product shelf life.
