Which Compound to Use to Manufacture a Bike Speedometer Housing

What Is It?

NEXXALENE™ Mineral Filled PP Compound reinforces PP with 15% to 40% mineral filler for higher surface finish and impact strength than unfilled PP, at a lower cost than glass-filled grades.

How It's Manufactured

Mineral filler is compounded into PP resin on a twin-screw line — mineral filler's even, non-directional dispersion behaviour in PP is what gives this grade its characteristic high-gloss surface finish after molding.

Manufacturing Process for This Application

Speedometer housings, mud guards, and cooler body panels are injection molded from the dried, mineral-filled compound, taking advantage of the grade's high flow and excellent processability to fill the housing's often-curved, cosmetically visible surface.

Why Polymer Choice Matters Here

A speedometer housing needs a clean, glare-free visible surface and enough impact resistance to survive vibration and minor road debris impact, without the added cost of glass fiber reinforcement this cosmetic, moderately-loaded part does not actually need.

Why This Compound Is Suited

The grade's "high flow with excellent processability, excellent surface finish with gloss, high impact strength and balanced mechanical properties" is exactly the profile a speedometer housing needs, and it is explicitly listed as an application.

Nexxa Compounds is a leading manufacturer of PP compounds for bike speedometer housing applications in India, supplying some of the largest manufacturers across India and internationally.
