What Is It?
NEXXALITE™ Unfilled PBT Compound, chosen for its highly reproducible mould shrinkage.
How It's Manufactured
PBT resin is compounded on a twin-screw line, relying on its crystalline structure for consistent, predictable shrinkage from mold to finished part.
Manufacturing Process for This Application
Bearing gauge components are injection molded to tight dimensional tolerances that directly determine measurement accuracy, using PBT's rapid, reproducible molding cycle to hold that tolerance across a full production run.
Why Polymer Choice Matters Here
A gauge component's entire value is its dimensional accuracy — a polymer with less predictable or less reproducible shrinkage would introduce measurement error directly into the part's function, which a general-purpose polymer without PBT's crystalline consistency cannot reliably avoid.
Why This Compound Is Suited
"Bearing gauges" is explicitly listed among this grade's applications.
Nexxa Compounds is a leading manufacturer of PBT compounds for bearing gauge applications in India, supplying some of the largest manufacturers across India and internationally.
