Say in-optimize ya particle density to (0.45 - 0.58g/mL) et mamapasimpli ed maabig ya iyaagus na melt diad parehon extrusion tan injection molding, bangta say moderate ya plasticizer absorption (20 - 28g/100g) et mamapasimpli ed transisyon manlapud semi-rigid cable sheaths ya anggad abeban flexibility profiles. Say inkaregular na molecular chain et mamalemew ed saray depekto ed panagproseso, pian naseguro so pareparehon kapal na dingding ed pangipaway na tubo.

SG7 (Rigid Engineering Grade)
Diad polymerization degree ya 700 - 850 tan K - value ya 60 - 62, say SG7 et mangiiter na prayuridad ed molecular packing efficiency parad rigidity. Say kompakton 40 - 180μm ya particle structure to (density 0.50 - 0.62g/mL) et mamapaabeba ed saray void ed saray molded parts, ya mamaaligwas ed impact resistance ed saray profile na bilding. Say abeban plasticizer absorption (15 - 22g/100g) et mangiiter na sigpot a malet iran pormulasyon, bangta say residual vinyl monomer ≤3μg/g et makaabot ed saray estandarte na food - contact safety parad saray aplikasyon ed panagbalot.

Ekosistema na Aplikasyon

SG3: Say Flexibility Specialist
Diad sektor na agrikultura, saray SG3 - based films ya walay 40 - 50 phr ya plasticizer ya kaaruman et manporma na UV - stabilized greenhouse covers, ya manbabalanse ed transmisyon na liwawa ed biskeg na tear resistance. Parad medikal iran aplikasyon, say abeban monomer content to et mamapawala na anlemew a tubo parad saray makinan panag-dialysis, bangbalet diad sapatos, makapanggawa na elastic soles ya mansiansian kurti anggano manguuman so temperatura.

SG5: Say Industrial Workhorse
Saray managgaway kable et manguusar ed 10 - 20 phr plasticizer range na SG5 pian makagawa na flame - retardant insulation sheaths parad saray power grid, ya ikombina so electrical insulation tan mechanical durability. Diad panagpaalagey, onlelereg itan ed saray weatherproof sealing strips parad saray bintana, ya say moderate ya inka-malet to et ag-onkapuy so ozone. Saray injection - molded ya kabiangan na luluganan, a singa say door trims, et nagunggonaan ed impact - biskeg - ed - belat ratio to.

SG7: Say Kampeon ed Inkapekder
Saray sistema na tubo ed industriya et mandedependi ed atagey a modulus na SG7 parad saray tubo na imburnal ya ag-onkukurang ed kemikal tan saray pressure-rated water mains. Saray extruded window profiles, no i-blend ed titanium dioxide, et mangipapatnag na nikadkaduman inka-colorfastness ed paway na kaliberliber. Saray manggagawa na elektroniko et uusaren da itan parad injection-molde iran kagawaan, ya uusaren da so dimensional stability to legan ya atagey so temperatura na panag-assemble.

Giya ed Panag-optimize na Proseso

Thermal Management Nuances
Say SG3 et mankaukolan na istrikton panangontrol ed temperatura (160 - 180°C) pian naprebentaan so masakbay a pakabulok; anggan say 10°C ya overshoot et nayarin pansengegan na hydrochloric acid ya ompaway, ya pansengegan na yellowing. Diad pidumaan, say SG7 et makatepel na 180 - 200°C ya proseso, ya mamaabuloy na mas maples ya extrusion rates parad angkakabaleg iran tubo, balet no onlampas ed 210°C et walay peligro na molecular chain scission.

Additive System Design
Panagpabiskeg: Say SG3 et mankaukolan na 1 - 2 phr na calcium - zinc composite stabilizers pian nasumpal so thermal degradation legan na high - plasticizer processing, bangta say SG7 et mankaukolan labat na 0.5 - 1 phr lapud nabawasan so plasticizer - induced stress.
Lubrication: Amin ya grado et nagunggonaan ed 0.2 - 0.5 phr na polyethylene wax, balet say SG3 et nayarin mankaukolan na mas atagey ya dosis pian nabawasan so internal friction ed saray soft compound.
Saray Functional Additives: Saray antioxidants ed SG7 formulations et mamaparukey na serbisyo ed paway, bangta saray impact modifiers ed SG5 et mamaaligwas ed notch resistance parad saray aplikasyon ed ambetel a klima.

Ekselente ed Inhenyeriya ed Desinyo na Resin

Diad pangitipon na eksakton molecular engineering ed application-driven testing, say SG3, SG5, SG7 portfolio mi et mangiiter na pakayari ed saray manggagawa na produkto pian nalampasan da ray tradisyonal ya limitasyon na PVC. Manlapud inka-flexible ya nakaukolan parad saray medical disposables anggad integridad na istruktura ya kaukolan na atagey iran konstruksion, sarayan resin so mangipapanengneng na pankasakey na scientific rigor tan industrial practicality—ya mangiletneg na balon benchmarks parad performance-driven polymer solutions.
