Which Compound to Use to Manufacture a Washing Machine Housing

What Is It?

NEXXALENE™ Flame Retardant Unfilled PP Compound adds a halogenated FR-V2 additive package to the PP base, formulated for low smoke generation under fire exposure.

How It's Manufactured

The FR additive package is melt-compounded into PP resin on a twin-screw line, calibrated specifically for low-smoke behaviour under combustion — a meaningful safety consideration in an enclosed appliance housing where visibility and toxicity during a fire event both matter.

Manufacturing Process for This Application

Washing machine panels, instrument panels, and battery cases are injection molded from the dried FR PP compound. These are typically large, thin-walled housings, so the FR additive is chosen to meet flammability requirements without compromising PP's inherent high flow and easy fill of large panel geometry.

Why Polymer Choice Matters Here

A washing machine housing encloses a motor and heating element in a household setting — a non-FR housing represents a genuine fire-safety gap in a domestic appliance, which is why this grade's low-smoke FR-V2 rating, not just its mechanical properties, is the reason it is specified here.

Why This Compound Is Suited

This grade's explicit application list — "Instrument Panel, Bumper application, Connectors, Battery cases & Covers, Washing machine parts, Exterior and interior automotive parts, Electrical and electronic appliances" — directly names washing machine parts as an intended use.

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