PVC compound formulation: the roles of additives
PVC compounds combine resin with additives selected for the application.

PVC compounds combine resin with additives selected for the application. Plasticizers influence flexibility, stabilizers support heat stability during processing and lubricants affect processing behaviour. Fillers and pigments also influence mechanics and appearance. Evaluate these components as a system rather than in isolation.
Where to start formulation development
Define finished-product hardness, mechanical targets, appearance and processing conditions. Record each additive's identity and loading, evaluating changes through controlled experiments. Track effects on other properties when increasing one component. A formulation from another product should not be copied without validation on your equipment against your specification.

Plastay Compounds — Flexible and rigid PVC compound
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.
Discuss your application with the technical team →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 →ASMIX — Lead-based PVC stabilizer
Review destination-market and application-category restrictions before selecting a lead-based system. Technical performance does not establish regulatory suitability. When evaluating a Ca-Zn alternative, compare thermal stability, lubrication balance and finished-product tests together.
