PVC resin for wire and cable.
Insulation has to stay flexible, hold its electrical properties and pass test after test on the same line. That starts with a resin made for cable work, not a general purpose grade pushed into the job.
Grade selection
Insulation, sheathing and the duct around them.
Core insulation, outer sheath and the conduit the cable runs through each ask for something different from the resin. These are the SIAMVIC® grades we supply for the cable industry.
K 71 · Suspension
SIAMVIC® 271PA
The cable grade. Made for wire and cable insulation, with good electrical properties and easy processing. A high K value gives the compound body and strength.

Flexible · Suspension
SIAMVIC® 266GB
The soft grade. Listed by AGC Vinythai for hose and cable extrusion, and for electric wire and cable, as well as soft and semi-rigid profile work.

K 66 · Suspension
SIAMVIC® 266RC
The duct grade. Used for electric ducts and conduit, the rigid pipe your cable runs through. K value 66, residual VCM of 1 ppm or less.

Which grade for which job
All three are suspension resins. A higher K value carries more body and strength in the compound; a lower one flows more easily. Your plasticiser, filler and stabiliser package sets the final properties.
The values shown are typical figures for grade selection, not specifications. Actual specifications come with the quality certificate issued for each shipment. Only the technical data sheet published on the official AGC Vinythai website is deemed valid. Safety data sheets are available on request.
| Grade | K value | Processing | Typical use |
|---|---|---|---|
| SIAMVIC® 271PA | 71 | Extrusion | Wire and cable insulation |
| SIAMVIC® 266GB | — | Hose & cable extrusion, calendering | Electric wire and cable, soft profile, hose |
| SIAMVIC® 266RC | 66 | Extrusion, injection | Electric ducts and conduit |
