Spansil Floats: Technical data sheet

Our proposal of Floats:

The spansil technology is our first choice in the design and production of qualitatively and technically excellent NBR floats. Reliability and repulsion of the Spansil material towards other materials is fundamental to guarantee a correct and enduring work condition. Spansil floats are made with NBR (a type of synthetic rubber) and closed microcells expanded ebonite.
Spansil is an official trademark registered by StilGomma Srl.

Customer care and service

We offer the customer a purchase experience simultaneous to a series of ancillary services that put vocational training and help in the choosing of the float in the first place, together with its final aesthetic features that determine the end result and through which the product is completed. The construction of a float is a complex process that requires a lot of patience, dexterity and experience: nouns that have let us take giant steps in the design of NBR floats.
