Material consistency evaluation and thermodynamic
Service Introduction
Because plastic is a formulation system composed of basic resins and a variety of additives, raw materials and processes are difficult to control, resulting in the actual production and product use process often different batches of product quality, or the materials used are different from the qualified materials when the design is finalized, even if the supplier says that the formula has not changed, Abnormal failure phenomena such as product breakage still occur frequently in the production and use of the product.
In order to improve this failure phenomenon, GRGTEST provides material consistency evaluation and thermodynamic analysis. GRGTEST is committed to quality control by helping enterprises establish a consistency map.

Service content and process
GRGTEST is committed to quality control by helping enterprises establish a consistency map.
● Screening of qualified products
The factory selects the products/materials that meet the requirements through various type tests
● Establish a reference spectrum
Qualified products/materials are analyzed by infrared spectral analysis (FTIR), thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), reference maps are established, and unique fingerprint passwords are obtained and retained in the enterprise database.
● Consistency analysis of products under test
During sampling, the data of the samples to be tested are compared under the same conditions to analyze whether the formula is changed; With the fusion index, linear expansion coefficient and other basic thermodynamic performance testing, help customers in a short time spot check product quality, economic and efficient control of suppliers of raw materials.
