Molecular Design & Physical Attributes

SG3 (A sang - A nemmi tlukruannak)
Polymerization degree 1300 - 1500 le K - value 70 - 72 he sermi, hi grade nih hin plasticizer tlaih khawhnak a tthantertu molecule hri sau a langhter. A 60 - 250μm tthencheunak nih a nemmi thilri sernak ah aa khatmi tthencheunak a tuah, 100g resin ah 25 - 35g plasticizer laknak a tuah. A chuakmi amorphous structure nih a tthen tikah a hlei in sauhnak a pek, cu nih cun a tthen lonak um loin a let lengmang in thlen a herhmi thilri caah a ttha.

SG5 (Versatile Medium - Grade)
Polymerization degree 1000 - 1100 le K - man 65 - 67 tlukruannak, SG5 nih aa thleng lengmangmi a laifang hmun a pek. A ttha bikmi particle density (0.45 - 0.58g/mL) nih extrusion le injection molding pahnih ah a tluangmi melt flow a tuah khawh, cu lioah a tlawm deuhmi plasticizer laknak (20 - 28g/100g) nih a tlawm deuhmi cable sheaths in a niam deuhmi - flexibility profiles ah thlennak a tuah khawh. Molecular chain a tlarimi nih thil tuahnak tlamtlin lonak a zorter, pipe chuahnak ah aa khatmi vampang a thuhnak a hngalhter.

SG7 (Rigid Engineering Grade)
Polymerization degree 700 - 850 le K - man 60 - 62 he, SG7 nih a fekmi caah molecule packing tthatnak kha a biapi ah a chiah. A tlawmmi 40 - 180μm particle structure (density 0.50 - 0.62g/mL) nih a sermi thilri hna ah a ummi a tlawmter, inn saknak sining ah hnahnawhnak a doh khawhnak a ṭhanchoter. A tlawmmi plasticizer laknak (15 - 22g/100g) nih a tlingmi a fekmi sernak a tuah khawh, cu lioah a tangmi vinyl monomer ≤3μg/g nih rawl - pehtlaihnak himnak phunglam kha thilri chiahnak caah a tlinh.

Hmannak Ecosystem

SG3: The Flexibility Specialist
Cinthlaknak lei ah, SG3 - hrambunhmi zukcawl hna cu 40 - 50 phr plasticizer chapmi he UV - a fekmi greenhouse khuhnak an ser, ceunak kuatnak le mitthli khamnak thazaang kha an i tlukter. Sii lei hmannak caah, a tlawmmi monomer nih dialysis seh caah a nemmi tubing a tuah khawh, cu lio ah kedan ahcun, lum le kih aa thleng lengmangmi ah a muisam a tlaih pengmi a nemmi kedan a ser.

SG5: Riantuannak Sahrang
Cable sertu hna nih SG5's 10 - 20 phr plasticizer range kha mei-alh a kham khomi khamnak hri pawl sernak caah an hman, electric mei khamnak le seh thilri fekmi kha an fonh. Inn saknak ah, thlalang caah nikhua nih a den khawh lomi kharnak hri ah a chuak, cuka ahcun a tlawmpal a harmi nih ozone rawhnak a doh. Injection - in sermi mawtaw thilri hna, innka hrennak tibantuk hna nih a tthawnnak - le - ritnak zat in hlawknak an hmuh.

SG7: The Rigidity Champion
Riantuannak pipe system hna nih SG7's a sangmi modulus kha chemical - a doh khomi ti thiang pipe le pressure - rated ti pipe caah an i bochan. A chuakmi thlalang sining hna cu, titanium dioxide he cawh tikah, lenglei pawngkam ah a hlei in rong a fekmi an langhter. Electronics sertu hna nih cun injection - molded appliance housing caah an hman, a lum tukmi fonh lio ah a tthatnak kha an hman.

Riantuan ning tthaternak lamhruainak

Lungthawhnak Uknak A Tlangmi
SG3 nih a caan hlan ah rawhnak hrial khawhnak ding caah lum le lum lo uknak (160 - 180°C) fek tein a herh; 10°C a luan hmanh ah hydrochloric acid a chuahter khawh, cu nih cun a sennak a chuahter khawh. Cu he aa dang in, SG7 nih 180 - 200°C riantuannak a tuar khawh, a nganmi - diameter pipe caah rang deuh in chuah khawhnak a tuah, asinain 210°C a lonh ahcun molecule chain tthennak a chuak kho.

Additive System Design
Tthawnnak: SG3 nih 1 - 2 phr calcium - zinc composite stabilizers a herh i plasticizer tam tuk tuah lio ah lumnak rawhnak doh khawh a si, SG7 nih cun plasticizer nih a chuahtermi lungretheihnak a zor caah 0.5 - 1 phr lawng a herh.
Hnawmhnak: Phun vialte nih 0.2 - 0.5 phr polyethylene wax in ṭhatnak an hmuh, asinain SG3 nih a nemmi thilri hna ah a chunglei hnahnawhnak zorternak caah a tam deuhmi a herh men lai.
Riantuannak Additives: SG7 sernak ah a ummi antioxidants nih lenglei riantuannak caan a sauter, cu lio ah SG5 chung i hnahnawhnak thlennak nih khuasik - khuacaan hmannak caah notch doh khawhnak a ṭhanchoter.

Resin Design ah Engineering thiamnak

A dikmi molecule engineering kha hmannak in hneksaknak he fonh in, kan SG3, SG5, SG7 portfolio nih thilchuaktu hna kha hlanlio PVC rikhiahnak hna kha lonh khawhnak thazaang a pek hna. Sii lei hman khawhmi thilri caah a herhmi nemnak in inn sangpi saknak nih a herhmi dirhmun tthatnak tiang, hi resin hna nih hin scientific rigor le industry hman khawhnak fonhnak kha a langhter—riantuannak - nih a hruaimi polymer thlennak caah tahfung thar a ser.
