Rigid PVC: grades, applications, and European suppliers
Unplasticised polyvinyl chloride. Used in window profiles, pressure pipe, and rigid sheet. Suspension grades dominate Europe.

European market context
European PVC capacity totals roughly 5.5 million tonnes per year (rigid + flexible combined), led by INOVYN (INEOS), Vestolit, Vynova, Kem One, and SCG/Cires. Rigid PVC (PVC-U) takes around 70% of total volume — pipe (sewer, drainage, conduit), profiles (windows, sidings), rigid sheet, and bottle. Window profile is the single largest application across Europe.
Suspension-grade PVC dominates supply for rigid applications. K-value (a measure of molecular weight) defines processability: K57–K60 for injection molding, K65–K68 for pipe and profile extrusion, K70+ for plasticized formulations. Most rigid converters specify K65 or K67 from a familiar formulation house.

What drives PVC-U pricing
PVC follows the European Vinyl Chloride Monomer (VCM) contract, which itself tracks ethylene plus chlorine economics. Chlorine pricing is set by chlor-alkali balance — caustic soda is the byproduct, and caustic demand swings drive chlorine availability and PVC margins by hundreds of euros per tonne.
Watch ICIS PVC suspension-grade weekly. The PVC-VCM-ethylene cost stack reveals whether margin pressure sits with the chlor-alkali producer or the PVC compounder. European producers run at 75–85% utilization in normal years; sub-70% triggers force majeure declarations and price spikes.
Regulatory landscape
REACH heavily impacts PVC formulation. Phthalate plasticizers DEHP, DBP, BBP, and DIBP are SVHC-restricted under Annex XVII; rigid PVC is mostly unplasticized but stabilizer chemistry (lead, tin, calcium-zinc) has shifted dramatically — lead stabilizers were voluntarily phased out by VinylPlus in 2015.
VinylPlus 2030 commitments push recycled content adoption in profile and pipe. CPR EN 50575 governs cable conduit fire performance. Pressure pipe is certified under EN 1452 (water) and EN 1401 (sewer drainage).
Sourcing options
Producer-direct contracts are typically reserved for high-tonnage buyers (1,000+ t/year minimum) negotiating monthly against monomer indices.
Distributors (e.g. Resinex, Ravago Distribution, Vinmar Polymers Europe) break bulk, hold local stock, and offer credit. Lead times 1–3 days for stock items.
Traders work the spot market for prime, near-prime and off-grade lots, typically 5–20% above or below contract reflecting near-term tightness. Polymer Platform routes RFQs to verified traders and distributors with the right grade and region match.
