Standard Testing, Strict Quality Control

Shuode Technology runs a professional laboratory with standardized inspection systems for strict quality control from raw materials to finished foam sealants.
1.Moisture Content Determination
We test multiple samples repeatedly with moisture analyzers to control errors, preventing premature reaction and consistent foaming effect.
2.Hydroxyl Value Determination
Hydroxyl value is measured with fume hoods and oil baths to stabilize raw material activity and uniform chemical reaction.
3.Propellant Analysis
Gas chromatograph detects propellant components to stabilize injection pressure for smooth extrusion and even foaming.
4.Finished Foam Density Determination
Density testers standardize foaming ratio, structural strength, thermal and sound insulation performance.
5.Viscosity Determination
Viscosity meters control base fluid viscosity, delivering consistent, smooth construction experience.
Every can of Shuode foam sealant passes precise lab tests and stands the test of the market.
