Industry-specific testing solutions
Specialised testing protocols for demanding applications.
Intrinsic Viscosity (IV) testing for rPET quality
IV measurement determines molecular weight and degradation. Starlinger and EREMA lines need precise IV control for bottle-grade rPET.
MFI testing for film & sheet production
MFI correlation (2–8 g/10min for LDPE film) ensures consistent melt flow. Real-time testing reduces scrap and holds gauge tolerance.
Incoming raw-material QC testing
Verify supplier consistency before production. Batch-to-batch MFI variation >10% flags material issues early.
"In polymer processing, precision isn't optional — it's survival. We reduced reject rates from 12% to under 2% simply by implementing proper MFI testing protocols. Investing in US-engineered Dynisco equipment delivers 10× ROI through reduced waste, minimised downtime and unmatched accuracy."
Did you know?
Critical testing facts that impact your production quality.
A 2°C temperature deviation during MFI testing can cause 15–20% variation in flow-rate readings, leading to incorrect material selection and production failures.
PET bottle manufacturers lose ₹50–80 lakhs annually to improper IV monitoring. Recycled PET below 0.72 dL/g fails bottle production, causing batch rejection.
Film lines running 24/7 consume 200–500 kg/hr. A 5% MFI variation means thickness fluctuation and ~30 kg/hr scrap — lakhs in monthly LDPE waste.
