SERBIA PVC PROFILE GUIDE
How to Select Masterbatch for PVC Profiles in Serbia
For PVC profile projects in Serbia, masterbatch should be selected against the producer's actual formulation, stabilizer package, profile geometry, surface target, and serial-production controls—not by color code alone.

How to Identify PVC Profile Project in Serbia?
Before the offer, formulation and process information, as well as the target color, should be clarified. The same RAL code may give different surfaces and undertones in different PVC, filler or stabilizer packages.
formulation and stabilizer information
PVC type, CaZn or other stabilizer system, filler ratio, processing aid, and pigments available are included in the technical evaluation. Products should not be selected based solely on the color card without sharing formulation variables.
Profile geometry and surface
Window profile, technical profile, panel or auxiliary part; may require different sample conditions in terms of thickness, gloss and texture. The approval sample must be representative of the surface in series production.
How to Check Color and Process Compatibility?
Laboratory color matching is the first step. The final decision should be made in a small-scale production trial with the customer's actual raw material and line condition.
Dispersion and thermal stability
Lines, dots, tonal shifts or brightness differences across the profile; It may be related to the mixture, screw, temperature and waiting time as well as the masterbatch. Controls are carried out using a single variable approach.
Tolerance and limit sample
The approved physical part, measurement method, light condition and acceptance range are recorded together. Lot continuity is verified more quickly by using the same reference for repeat orders.
Transition Plan from Sample to Order
In order for the regional sales process to be reliable, technical data, samples, line trials and commercial offers must proceed in conjunction with each other. The delivery method and required documents are also verified at the offer stage.
Technical package to share
Raw material name, formulation summary, target color, current part, usage rate, profile cross-section, line temperatures and annual or batch-based need are shared on the same sample form.
Mass production approval
After the laboratory sample, a controlled trial is carried out on the real line. The approved dosage, formulation code, process window and physical reference create a traceable record for subsequent orders.
Short Technical Answers
Is a separate PVC masterbatch formulation required for Serbia?
The country name alone does not determine the formulation. If the customer's PVC, stabilizer, filler, process and color target are different, project-specific verification is required.
Is the RAL code sufficient to place an order?
RAL is a strong starting reference; However, final color approval should not be given without taking samples of the actual PVC raw material, surface and profile thickness.
How to maintain color on repeat order?
The new lot is checked with the same reference by keeping the approved part, measurement values, formulation code, raw material and process notes.
