The SRL-Z series experimental hot & cold mixing unit is a compact laboratory-grade solution designed for PVC formulation research, polymer compounding experiments, and small-batch material testing. It integrates high-speed hot mixing and controlled cooling mixing into a single system, enabling precise evaluation of material behavior before industrial-scale production.
This system is widely used in:
Polymer R&D laboratories
PVC formulation development centers
Universities & technical institutes
Material testing and pilot production lines
Small-scale additive and modifier experiments
Built with a dual-stage mixing concept, the system first performs high-speed thermal mixing (hot mixing) to ensure uniform dispersion, followed by controlled cooling mixing to stabilize the material and prevent agglomeration.
The SRL-Z experimental mixer operates in two integrated stages:
PVC powder and additives are fed into the hot mixing chamber
Frictional heat and optional electric heating rapidly raise material temperature
Additives are fully absorbed into PVC resin
High-speed impeller ensures uniform dispersion and plasticization behavior analysis
Material is automatically discharged into the cooling mixer
High-efficiency water circulation cooling system rapidly reduces temperature
Prevents thermal degradation and material sticking
Ensures stable material storage and handling properties
This hot–cold transition simulates industrial PVC compounding conditions on a laboratory scale.
