Premium PVC Resins SG3, SG5, SG7: Tailored Engineering para keng End - to - End Industrial Solutions

Molecular Design & Physical Attributes

SG3 (Matas - Flexibility Grade)
Megawa ya keng polymerization degree a 1300 - 1500 ampo K - value a 70 - 72, ining grade atin yang makaba a molecular chains na magpasanting keng plasticizer entrapment. Ing kayang 60 - 250μm particle distribution sisiguraduan na ing pare-pareung pamikalat kareng malambut a compound formulations, a magpaintulut 25 - 35g ning plasticizer absorption balang 100g resin. Ing resulta ning amorphous structure mamye yang exceptional elongation keng break, gagawan neng masanting para kareng produktung mangailangan paulit-ulit a pamag-flex a alang crack.

SG5 (Versatile Medium - Grade)
Ing pamagbalanse keng polymerization degree a 1000 - 1100 ampo ing K - value a 65 - 67, ing SG5 mag offer yang dynamic middle ground. Ing kayang optimized particle density (0.45 - 0.58g/mL) papasimpli na ing makinis a melt flow keng extrusion ampo injection molding, kabang ing moderate plasticizer absorption (20 - 28g/100g) papalyarian na ing pamagbayu ibat keng semi - rigid cable sheaths papunta keng low - flexibility profiles. Ing molecular chain regularity babawasan na ing depektu keng pamagprosesu, makasiguradung parehu ing kapal ning pader keng pipe extrusion.

SG7 (Rigid Engineering Grade)
Kareng polymerization degree a 700 - 850 ampo K - value a 60 - 62, ing SG7 mumuna ya keng molecular packing efficiency para keng rigidity. Ing kayang compact 40 - 180μm a particle structure (density 0.50 - 0.62g/mL) babawasan na ing voids kareng molded a bage, papaslag ne ing impact resistance kareng profile ning gusali. Ing mababang plasticizer absorption (15 - 22g/100g) paintulutan na ing ganap a rigid a formulasyun, kabang ing residual vinyl monomer ≤3μg/g makatupad ya kareng food - contact safety standards para kareng packaging applications.

Application Ecosystem

SG3: Ing Flexibility Specialist
keng agrikultura, SG3 - based films a maki 40 - 50 phr plasticizer a karagdagan gagawang UV - stabilized greenhouse covers, babalanse ing light transmission ampo ing tear resistance strength. Para kareng medikal a aplikasyun, ing kayang mababang monomer content papalyarian na ing malambut a tubing para kareng dialysis machines, kabang keng sapatus, gagawang elastic soles na manatili ing porma na keng pamagbayu ning temperatura.

SG5: Ing Industrial Workhorse
Deng gagawang cable gagamitan de ing SG5's 10 - 20 phr plasticizer range para makagawa lang flame - retardant insulation sheaths para kareng power grids, a pisamut ing electrical insulation ampo ing mechanical durability. keng konstruksyun, mag extrude ya keng weatherproof sealing strips para kareng bintana, nung nukarin ing kayang katamtaman a katigasan lalaban ya keng ozone degradation. Deng injection - molded automotive components, antimo reng door trims, makinabang la keng impact - strength - to - weight ratio.

SG7: Ing Rigidity Champion
Deng industrial piping systems magdependi la keng matas a modulus ning SG7 para kareng chemical - resistant sewer pipes ampo pressure - rated water mains. Deng extruded window profiles, nung iyabe la keng titanium dioxide, magpakit lang pambihirang colorfastness keng kilwal a kapaligiran. Deng gagawang electronics gagamitan de iti para keng injection - molded appliance housing, gamitan de ing kayang dimensional stability kabang mag-assemble la keng matas a temperatura.

Gabay king Pamag-optimize king Prosesu

Thermal Management Nuances
Ing SG3 mangailangan yang mahigpit a pamagkontrol keng temperatura (160 - 180°C) para aiwasan ing e pa panaun a pangasira; agyang 10°C overshoot malyari yang maging sangkan ning pamagluwal ning hydrochloric acid, a magdalang pamagdilaw. Ing pamiyaliwa, ing SG7 agyu nang 180 - 200°C ing pamagprosesu, a magpaintulut king mas mabilis a extrusion rates para kareng mangaragul a diameter a pipe, dapot ing pamaglampas king 210°C atin yang panganib a molecular chain scission.

Additive System Design
Stabilization: Ing SG3 mangailangan yang 1 - 2 phr ning calcium - zinc composite stabilizers para labanan ing thermal degradation kabang matas ya ing pamagprosesu ning plasticizer, kabang ing SG7 mangailangan yang 0.5 - 1 phr uling mabawas ing plasticizer - induced stress.
Lubrication: Deng eganaganang gradu makinabang la keng 0.2 - 0.5 phr ning polyethylene wax, pero ing SG3 malyari yang mangailangan mas matas a dosis para mabawas ing internal friction kareng malambut a compound.
Functional Additives: Deng antioxidants kareng SG7 formulations papalual da ing outdoor service life, kabang deng impact modifiers keng SG5 papaslag da ing notch resistance para kareng cold - climate applications.

Kagaling ning Inhinyeriya keng Disenyu ning Resin

Kapamilatan ning pamisanmetung ning eksaktung molecular engineering ampo ing application - driven testing, ing kekaming SG3, SG5, SG7 portfolio babie na ing upaya kareng manufacturer para lampasan ing tradisyunal a limitasyun ning PVC. Manibat keng flexibility a kailangan para kareng medical disposables angga na keng structural integrity a kailangan ning matas a konstruksyun, deng resin a reni maglaman lang pamisanmetung ning scientific rigor ampo ing industrial practicality—mag set lang bayung benchmark para kareng performance - driven polymer solutions.
