Ukukhutshwa kwe-VOC: <5 μg/m³ (ISO 16000-6)
Ukuguquguquka kobushushu obuphantsi: Iyagobeka kwi-60 ° C (Akukho kuqhekeka)
2. PU Synthetic Isikhumba: Yellowing Resistance: ΔE > 8.0 (200 iiyure)
Ukumelana ne-Hydrolysis: Ukuqhekeka kwi-70 ° C kwiiyure ezingama-96 (ASTM D2097)
UkuBuyiswa komlilo: UL94 HB (UkuBusa kancinci)
Ukukhutshwa kwe-VOC: > 300 μg/m³ (Iqulethe iDMF/Toluene)
Ukuguquguquka kobushushu obuphantsi: Ibhityile ku -20°C
3. PVC Synthetic Isikhumba: Yellowing Resistance: ΔE > 15.0 (100 iiyure)
Ukumelana ne-Hydrolysis: Ayisebenzi (Ayisebenzi kuvavanyo)
Ukubuyiswa komlilo: UL94 V-2 (Iiginishini evuzayo)
Ukukhutshwa kwe-VOC: >> 500 μg/m³ (kuquka iDOP)
Ukuguquguquka kobushushu obuphantsi: Inyanga kwi-10°C
IV. Iimpawu zokusingqongileyo kunye noKhuseleko
1. Isikhumba seSilicone:
I-Biocompatibility: ISO 10993 ibakala lonyango eliqinisekisiweyo (umgangatho wofakelo)
Ukuphinda kusetyenziswe: Ioyile yeSilicone ifunyenwe ngokuqhekeka kwe-thermal (izinga lokubuyisela> 85%)
Izinto ezinetyhefu: Isinyithi esinzima-free/halogen-free
2. Isikhumba sokwenziwa
I-Biocompatibility: Umngcipheko wokucaphuka kolusu (uqulethe i-isocyanates yasimahla)
Ukurisayikilisha: Ukulahlwa kwetiphu (akukho kuthotywa komgangatho kwiminyaka engama-500)
Izinto ezinetyhefu: I-PVC iqulethe i-lead stabilizer, i-PU iqulethe i-DMF
UkuSebenza koQoqosho lweSetyhula: Isikhumba se-Silicone sinokuhluthwa ngokwasemzimbeni ukusuka kwisiseko sesiseko ukuya kwi-silicone layer for re-granulation. Isikhumba se-PU/PVC sinokuthotywa kuphela kwaye siphinde sisetyenziswe ngenxa yokudityaniswa kwemichiza. V. Iimeko zeSicelo
