What PVC is used for
Polyvinyl Chloride (PVC) is a rigid, amorphous thermoplastic resin supplied as a fine powder (suspension or emulsion resin) or as compounded pellets. It is produced by the free-radical polymerisation of vinyl chloride monomer (VCM), mainly by the suspension process, with emulsion and bulk (mass) polymerisation used for specific grades.
PVC's uses split broadly into rigid (unplasticised, uPVC) applications — pressure and sewer pipe, window profiles, siding and rigid sheet, valued for chemical resistance and long-term strength — and flexible (plasticised) applications, where the addition of phthalate or non-phthalate plasticisers produces cable and wire insulation, flexible film and sheet, vinyl flooring, and medical tubing and blood bags.
Where it sits in the petrochemical value chain
- Vinyl Chloride Monomer (VCM) the sole monomer, polymerised into PVC resin. See that page.
- Polyvinyl Chloride (this product) the rigid or compounded-flexible resin for pipe, profile, cable and film applications.
- Ortho-Xylene / Phthalic Anhydride the plasticiser feedstock chain for flexible PVC compounds. See Ortho-Xylene.
Handling character
PVC resin is not classified as hazardous under normal handling, though fine powder presents a combustible-dust risk. Full handling detail is in the Safety section below.
| Parameter | Typical value |
|---|---|
| Appearance | White powder or pellets |
| K-value | 57-70 (grade dependent) |
| Bulk density | 0.45-0.65 g/cm³ (powder resin) |
| Residual VCM content | < 1 ppm (food-contact grades) |

| Property | Value |
|---|---|
| Physical state | Solid, rigid powder or pellets |
| Glass transition (Tg) | ~80 °C |
| Density | 1.3-1.45 g/cm³ (unplasticised) |
| Processing temperature | ~160-210 °C |
| Chemical resistance | High resistance to acids, alkalis and salts |
| Flammability | Self-extinguishing (inherently flame-retardant due to chlorine content); fine dust can be combustible |

How we supply Polyvinyl Chloride (PVC)
Chelora Chemicals is a supplier and sourcing partner, not a manufacturer. K-value consistency and residual VCM content are critical to pipe, profile and medical-grade performance — that shapes how we manage this line.
We place your order with whichever qualified producer best matches your required grade, your price point and your delivery window, and confirm your jurisdiction's import requirements before booking.
We keep a second qualified source on this line, so a single-plant disruption never becomes your production problem.
- K-value and residual VCM confirmed before we quote. Consistency matters to downstream pipe, profile and medical-grade performance.
- Food-contact and medical compliance documented. Grade-specific compliance paperwork confirmed before booking where required.
- Scheduled call-off scheduling. We hold contracted tonnage and release it against your consumption calendar.
- Batch traceability to the producing plant. Full chain of custody documentation on request.
- Export machinery handled in-house. Classification, approved packing, labelling, freight booking and customs paperwork are ours to manage.
- Pipe, profile and compounding grades all sourced. Matched precisely to your processing specification.

Non-hazardous solid resin — handle sensibly
PVC resin powder is not classified as hazardous under GHS for normal handling, but combustible-dust and molten-polymer precautions still apply during processing. The summary below is orientation only — the safety data sheet supplied with your specific batch is the authoritative document.
Classified hazards
Not classifiedPowder/pellet resin is not classified as hazardous under GHS.Dust noteFine powder may form combustible mixtures with air and should be controlled accordingly.
Keep dust controlled and avoid overheating during processing. PVC can release hydrogen chloride if processed above recommended temperatures; manage static and follow equipment manufacturer guidance. Always read the SDS issued with your specific batch.
Storage
Store bagged or bulk resin in a dry, covered area away from direct sunlight and heat sources to protect against premature degradation.
Handling
Standard PPE (gloves, dust protection) is sufficient for normal handling. Observe hot-surface and off-gas precautions during extrusion, calendering or moulding of the molten compound.
Transport
Not classified as dangerous goods for transport in powder/pellet form. We confirm any destination-specific import, food-contact or medical-compliance documentation your shipment requires.
Every batch, documented
We verify documentation before dispatch so there are no surprises at your incoming-goods bench.
Specification agreed
K-value, bulk density and residual VCM content confirmed against your process requirement before order placement.
Producer batch testing
The producing plant tests each batch against the agreed specification before release.
Documentation review
COA, SDS and transport/compliance paperwork checked by our desk before the shipment is booked.
Traceable dispatch
Each shipment is traceable to its producing batch, with full chain-of-custody records on request.
How PVC is made
PVC is produced industrially by the free-radical polymerisation of vinyl chloride monomer, predominantly by the suspension process (VCM droplets suspended in water, polymerised with an oil-soluble initiator) which accounts for most commodity resin, with emulsion polymerisation used for paste-grade resins and bulk (mass) polymerisation for certain specialty grades.
We do not publish operating process parameters here; this is background only. Full technical documentation accompanies every shipment, and any process-specific detail you need is best confirmed directly with our technical desk.
