Processing studies of polyvinyl chloride
The Polymer Technology Research Group, Vinyl Polymer Section carries out research work in the field of polyvinyl chloride research to improve its properties while meeting the highest quality standards and environmental requirements.
We are the only team in Poland that conducts laboratory-scale studies of PVC synthesis by the suspension method in glass reactors.
We use a complete laboratory-scale process line for our research, which consists of:
→ 2 glass reactors with a capacity of 1.5 liters, with process data recording system
→ Spinner
→ Fluidized bed dryer
→ Hot-cold mixer – automatic (laboratory scale fully reflecting the industrial device) allowing the preparation of dry mixture in strictly established sequences in the amount of 2-5 kg
→ Brabender brand equipment for polyvinyl chloride processing tests.
Using this laboratory process line, we offer to carry out research work on polyvinyl chloride using the entire process line or a selected stage:
STAGE I: Research work in the polymerisation of vinyl chloride (PVC synthesis)
→ Development of new reaction formulation compositions to improve the quality of the obtained polyvinyl chloride
→ Optimization of PVC synthesis processes towards:
→ Increase productivity
→ Formulation compositions
→ Research toward developing types of PVC for new applications.
→ Study of the effect of individual components of the reaction mixture on the properties of PVC
→ Study of new auxiliary substances in the synthesis of PVC and determination of their influence on the quality of the obtained PVC
→ Research toward meeting the environmental requirements of the PVC synthesis process.
STAGE II: Research work in the preparation of dry mix (dry-blend)
→ Development of a dry mix recipe that meets specified performance characteristics
→ Development of a dry mix recipe that meets specific processing properties
→ Modifying the recipe for optimization:
– Composition
– Properties
– Prices
→ Study of the effectiveness of new processing agents and determination of their method of use (quantity, stage of introduction into the mixture) on the properties of the finished product and the processing process
→Quality testing of PVC compounds.
STAGE III: Processing studies
→ Gelation time
→ Dynamic stability
→ Determination of processing temperature of powders as well as plastic granulates
→ Performing viscosity measurements
→ Performing kinematic viscosity with a capillary nozzle
→ Extrudability tests
→ Analyses of test results and correlations with reference samples
→ Making a granular sample of the test mixture (dry blend).
The research facilities include:
→ MetaStation 4E – Torque rheometer with software and Internet connection
→ Conical twin-screw extruder – counter-rotating CTSE
→ Vertical auger dispenser
→ Extruder heads:
– slotted, flexlip type. Nozzle dimensions: 50 x 0.05 to 2.0 mm
– Rod head with 2 ¾” threaded ring, and interchangeable nozzles: Ø 3.0 mm, Ø 4.0 mm, Ø 5.0 mm
→ Planetary mixer P 600
→ Measuring rotor 50 EHT
→ Transport tape
→ Cooling bath
→ Granulator
→ Brabender-MetaBridge software for data correlation
