PVC additive selection in 2026: performance and evidence
Define the problem before evaluating a new additive.

Define the problem before evaluating a new additive. Lower discolouration, a particular hardness and stable processing with recycled feedstock are different goals. A newer additive is not automatically suitable for an existing formulation.
How to run a controlled trial
Use the current formulation as a reference and start with one changed variable. Record mixing order, temperature, line speed and specimen conditioning. Assess ageing, migration and colour change alongside initial mechanical results. For claims about bio-based or recycled content, request the calculation method and traceability documents; these labels alone do not establish a lower environmental impact.
Related products and technical evaluation
Sunfleks DOTP — DOTP / DEHT plasticizer
Select DOTP against the complete formulation: target Shore hardness, resin, filler loading, processing temperature and service conditions. When replacing DOP or DINP, validate the dosage in a pilot run and ageing tests rather than assuming identical mechanical performance at the same loading.
Discuss your application with the technical team →ASSAFE — Calcium-zinc (Ca-Zn) PVC stabilizer
Select a Ca-Zn system together with PVC resin, filler, plasticizer, lubrication balance and processing temperature. Initial colour and long-term thermal stability are distinct targets. Validate the grade and dosage through a production trial; the Ca-Zn designation is not automatic certification of the finished product.
Discuss your application with the technical team →Plastay Compounds — Soft and rigid PVC compound / granules
Start compound selection with the application, process and performance target. Assess hardness, flexibility and ageing for soft PVC; dimensional stability, impact and processing for rigid PVC. Portfolio ranges shown here are not guaranteed values for a single grade. Request a grade-specific data sheet and sample.
