T/TJWL 006-2022 Cold chain uses thermoplastic polyurethane (TPU) ice board

Scope

Main technical content: 4.2 First layer: Back-filling process (H). The product uses the back-filling process, indicated by "H". 4.3 Second layer: TPU ice plate/cooling plate name, represented by "TPU". 4.4 Third layer: Column number (two-digit). The code represents the actual number of columns in the cooling plate. If less than two digits, zeroes are added to the front; if more than two digits, it is uniformly represented as "99". 4.5 Fourth layer: Phase change temperature (one letter). The code represents the phase change temperature of the cooling plate: A for -2°C, B for -6°C, C for -10°C, D for -14°C, E for -18°C, F for -22°C. 4.6 Fifth layer: Color (one letter). The code represents the color of the cooling plate, corresponding to the first letter of the English name of different colors. B for blue, R for red, G for green, Y for yellow, X for others. Example: The product with the code H TPU 05 A R indicates a TPU cooling plate with -2°C, red color, and 5 columns, produced using the back-filling process. 5. Technical requirements 5.1 Raw materials 5.1.1 Coolant The coolant shall comply with the requirements of T/TJWL 004-2018. 5.1.2 TPU substrate 5.1.2.1 Dimensional deviation 5.1.2.1.1 The length and width of the TPU substrate shall not be less than 99.5% of the nominal value. 5.1.2.1.2 The thickness deviation shall be within ±0.02 mm.
