About  Float / floater
A float is part of device that measure the liquid level based on the up and down movements of the liquid level. Not only vehicle's fuel tanks, but also being widely used in other industrial equipments which need function or capability of measuring the level of different liquids.

Where float is used ?
1.Fuel tank level gauges (automobile, motorcycle, trucks etc.)
2.Carburetors (motorcycles, automobile, agricultural machine engines)
3.Engine oil level gauges
4.Transformer oil level indicator
5.LPG level gauges, valves
6.Industrial liquid level sensor
7.Other types of equipment that need level detection sensors

Notes: Currently FDS can supply the floats made of nitrile rubber, polyurethane and POM.

Nitrile rubber( NBR) introduction
To make sure the float itself can work perfectly in different liquids, the float material must be excellent in terms of resistance ability and durability against different liquids and extreme environment. This is why NBR and vulcanization foaming technology was highly recommended.
Nitrile Butadiene rubber, refer as NBR, is a kind of synthetic rubber, which has excellent fuel/oil resistance, high wearing, heat resistance, and good strong adhesion and aging resistance.
NBR float is a closed pore foam object composed of nitrile rubber, its self-independently sealed small space structure can completely block the liquid from penetrating, moreover, its Low liquid absorption rate and uniformity of the pore structure improves product reliability, which can avoid the sinking accident of the device used as the floating material due to the loss of buoyancy.
