SIAMVIC® 266RC
SIAMVIC® 266RC is a general-purpose K66 suspension PVC resin from AGC Vinythai PCL, Thailand, supplied in Bangladesh by Dunhill Corporation Ltd. — the authorized local agent since 1998. It is built for rigid work: pressure pipe, sewage pipe, window profile, electrical duct, SPC flooring and injection moulding.
Short answer: if you are extruding uPVC pressure pipe, sewage pipe, conduit or rigid window profile — or injection moulding fittings and shoes — 266RC is the AGC Vinythai grade written for that job. Its higher apparent bulk density (0.570 kg/l) and tight particle cut (≤ 2% on 60 mesh) mean better output per hour and fewer fish-eyes than a general soft-application resin.

What SIAMVIC 266RC is used for
These are the end uses listed on the manufacturer's own technical data sheet — not a general guess. In Bangladesh, the first two carry most of the volume.
Pressure & sewage pipe
uPVC water supply lines and drainage pipe. Consistent melt behaviour keeps your line settings stable through the shift.
Rigid profile & window frame
uPVC door and window profile extrusion, where surface finish and dimensional stability decide pass or reject.
Electric ducts
Rigid electrical conduit and ducting, where output speed and a low reject rate matter more than anything else.
Injected shoes & fittings
Injection moulded footwear, elbows, sockets, connectors and other technical rigid parts.
SPC flooring
Stone plastic composite flooring boards — a fast-growing line for Bangladeshi and regional producers.
PVC compounds
Base resin for rigid compounding houses supplying pipe, profile and fitting manufacturers.
