VOC Emissions:> 300 μg / m³ (muaj DMF / Toluene)
Tsawg-kub Flexibility: brittle ntawm -20 ° C
3. PVC Synthetic Leather: Yellowing Resistance: ΔE > 15.0 (100 teev)
Hydrolysis Resistance: Tsis siv tau (Tsis cuam tshuam rau kev sim)
Nplaim Retardancy: UL94 V-2 (Dripping Ignition)
VOC Emissions: >> 500 μg / m³ (nrog rau DOP)
Tsawg-Temperature Flexibility: Kho ntawm 10 ° C
IV. Environmental thiab Safety Features
1. Silicone tawv:
Biocompatibility: ISO 10993 kev kho mob-qib ntawv pov thawj (tus qauv cog)
Recyclability: Silicone roj rov qab los ntawm thermal cracking (rov qab tus nqi> 85%)
Tshuaj lom neeg: hnyav hlau-dawb/halogen-dawb
2. Synthetic tawv
Biocompatibility: Cov tawv nqaij khaus khaus (muaj cov isocyanates dawb)
Recyclability: Kev pov tseg pov tseg (tsis muaj degradation hauv 500 xyoo)
Cov tshuaj lom: PVC muaj cov hmoov lead ntsev stabilizer, PU muaj DMF
Circular Economy Performance: Silicone tawv tuaj yeem raug stripped ntawm lub hauv paus ntaub mus rau silicone txheej rau re-granulation. PU / PVC tawv tuaj yeem tsuas yog txo qis thiab rov ua dua tshiab vim muaj tshuaj lom neeg sib txuas. V. Application Scenarios
