Test Lab & Quality Control
At Sochen, we operate a fully equipped in-house test laboratory to ensure every batch of modified plastics meets strict international standards and customer requirements. Our quality control process covers raw material inspection, physical performance testing, flame retardancy evaluation and environmental compliance verification.
Key Testing Capabilities -
Mechanical Performance: Tensile strength, impact resistance, elongation at break and hardness testing per ISO 527, ISO 179 and relevant standards. -
Thermal Stability: Heat deflection temperature (HDT), vicat softening temperature and thermal aging tests. -
Flame Retardancy: UL94 vertical/horizontal flame testing to classify V0, V1, V2 and other flame retardant grades. -
Environmental Compliance: REACH, RoHS and heavy metal element detection to meet global regulatory requirements. -
Molding Processability: Melt flow rate (MFR) and rheology testing to optimize production efficiency. ## Quality Assurance All test results are documented and traceable, with complete test reports available upon request. We implement strict batch sampling and inspection protocols to guarantee consistent product quality from order to delivery.
