Polyvinyl Chloride (PVC)
The PVC resin supplied by Chelora Chemicals — a versatile vinyl polymer processed rigid or flexible across pipe, profile, film and cable applications — exported from Indonesia as virgin powder/pellet with full batch documentation on every shipment.
What PVC is, and why buyers source it
A working overview of the resin's chemistry, why it needs additives to be useful, and the grades Chelora Chemicals keeps in regular supply.
Polyvinyl Chloride is, unusually among the major commodity plastics, inherently rigid and heat-sensitive in its unmodified form — it is never sold or used as the bare polymer, but always as a formulated compound built around the base resin with stabilisers, and for flexible grades, plasticisers and other processing aids. The chlorine atom on every second carbon gives PVC good flame resistance and chemical resistance relative to other commodity resins, but also makes the polymer prone to releasing hydrogen chloride if overheated during processing, which is why heat stabilisers are an essential, non-optional part of every PVC formulation.
At room temperature the base resin is supplied as a white, free-flowing powder (from the dominant suspension process) or, less commonly, a finer powder from emulsion polymerisation suited to specialty plastisol applications. The powder itself carries no plasticiser; whether the finished compound ends up rigid (pipe, profile) or flexible (cable insulation, film) is decided entirely by how much plasticiser the compounder adds afterward.
Where it fits in the value chain
Rigid, unplasticised PVC (uPVC) is the dominant resin for pressure and drainage pipe, window profile and rigid sheet, valued for its stiffness, weathering resistance and low cost relative to other rigid thermoplastics. Flexible PVC, compounded with a phthalate or non-phthalate plasticiser, is used in wire and cable insulation, flexible film and sheeting, flooring, and medical tubing. Specialty emulsion-grade resin is used in plastisol applications such as dip-moulded gloves and automotive underbody coatings.
Grades we supply
Chelora Chemicals offers suspension-grade PVC for pipe, profile and film applications, across a range of K-values (molecular weight grades), and emulsion-grade resin for plastisol use. Each grade is supplied with a batch-wise certificate of analysis covering K-value, bulk density and particle size.
How PVC is produced
An overview of the production route for orientation purposes. Our manufacturing partners' own process parameters and in-process controls are proprietary and are not disclosed beyond what is needed to interpret the certificate of analysis.
PVC is produced predominantly by suspension polymerisation: vinyl chloride monomer is dispersed as fine liquid droplets in water using a suspending agent and agitation, then polymerised under a free-radical initiator at controlled temperature, which directly sets the resin's molecular weight (and therefore its K-value) — a lower polymerisation temperature gives a higher molecular weight and higher K-value resin. The resulting porous polymer particles are separated from the water phase, dried and screened, with unreacted monomer recovered and recycled for both economic and environmental reasons.
A smaller volume is produced by emulsion polymerisation, using a surfactant rather than a suspending agent to keep much finer monomer droplets dispersed, giving a finer, more uniform particle size suited to plastisol and paste applications where the resin is dispersed directly into liquid plasticiser without a separate melt-compounding step.
Industries and processes that use it
PVC is consumed across rigid pipe and profile, flexible cable and film, and plastisol applications. The fields below account for most of the demand we see through our export desk.
Pressure & Drainage Pipe
Compounded rigid and extruded into pressure pipe for water supply and non-pressure pipe for drainage and sewerage, the single largest PVC end use.
Window Profile & Rigid Sheet
Compounded rigid, often with impact modifiers and UV stabilisers, into window and door profile and rigid sheet for signage and cladding.
Wire & Cable Insulation
Compounded flexible with a plasticiser into cable insulation and jacketing, valued for flame resistance and electrical insulating properties.
Film, Flooring & Medical Tubing
Compounded flexible into film, flooring, and medical-grade tubing and blood-bag film, with a plasticiser and formulation matched to the regulatory requirement.
How the resin is typically compounded forward
The need for stabilisation, and the plasticiser decision, govern almost all of PVC's further formulation behaviour. The categories below account for most of the ways it is converted into a finished product.
Rigid Compounding (uPVC)
The base resin is dry-blended with heat stabilisers, impact modifiers, processing aids and fillers, with no plasticiser, to produce an unplasticised rigid compound for pipe, profile or sheet.
Flexible Compounding
The base resin is dry-blended with heat stabilisers and a substantial loading of plasticiser (commonly a phthalate or non-phthalate ester) to produce a flexible compound for cable, film or flooring.
Extrusion
Both rigid and flexible compounds are melt-extruded through a die into pipe, profile, sheet or cable-covering shapes.
Plastisol Dispersion
Fine emulsion-grade resin particles are dispersed directly into liquid plasticiser to form a paste (plastisol) that is dip-moulded, spread-coated or sprayed, then fused by heating without melt-compounding.
PVC against its feedstock monomer we supply
Buyers sourcing PVC resin often also need the vinyl chloride monomer it is polymerised from, for their own in-house polymerisation. A quick reference to what else is on our regular supply list.

Safety classification at a glance
Based on GHS classification as commonly listed for this substance. This is a summary for orientation only — always work from the current safety data sheet supplied with your specific batch.
The polymerised resin itself is not classified as hazardous under GHS; residual VCM content is controlled and checked.
Combustible, though more flame-resistant than most hydrocarbon-only polymers due to its chlorine content; emits dense smoke and HCl gas if burned.
Minimise airborne dust during handling; fine powder should be handled with standard combustible-dust precautions.
Releases hydrogen chloride gas if overheated during processing or involved in a fire; adequate stabilisation and fume extraction are essential.
Standard dust mask, gloves and eye protection are sufficient for routine handling of the powder resin.
Residual vinyl chloride monomer content is controlled to a low level and checked on every batch.
Not classified for the resin itself; refer to the batch MSDS for full detail, including residual monomer data.
The polymerised resin has a low hazard profile and is not classified as hazardous under GHS, though it should be handled with standard combustible-dust precautions given its fine powder form. The key process hazard is thermal: if overheated during melt processing, PVC releases hydrogen chloride gas, which is why every commercial PVC formulation must include an adequate heat stabiliser package and processing equipment should include appropriate fume extraction. Residual vinyl chloride monomer content, a recognised human carcinogen in its unreacted form, is controlled to a low level and reported on every batch certificate. Full first-aid, storage, spill and PPE guidance is in the MSDS issued with every shipment, and should be read in full before this material is handled.
Keeping it on spec between delivery and use
General storage guidance for this grade. Site-specific storage rules, segregation requirements and re-test intervals should follow your own EHS procedures and the MSDS issued with your batch.
Store in a dry, ambient-temperature warehouse, out of direct sunlight and away from heat sources, since moisture pickup in the fine powder resin can disrupt dosing accuracy and cause processing defects. Keep bags sealed to prevent moisture pickup and contamination with other resin grades or additives. Re-check K-value and moisture content on material held past its retest date before use.
