Product Description
Grafite espandibile
La grafite espansibile è un composto di intercalazione sintetizzato di grafite che si espande o esfolia quando viene riscaldata.una riduzione della densità di massaPoi viene compresso in un foglio flessibile altamente coeso.
Un'altra applicazione principale è come ritardante di fiamma.Questo rallenta la diffusione del fuoco e riduce al minimo uno degli effetti più dannosi della combustione: la creazione di gas e di fumi tossici.
Vantaggi della grafite espandibile come ritardante di fiamma:
- Forma uno strato di intumescenza con protezione dalle radiazioni termiche, con diffusione termica superiore.
- Ferma o rallenta la diffusione del fuoco e dei gas tossici.
- Facile da applicare, conveniente, prestazioni soddisfacenti con bassi livelli di aggiunta.
- Additivo antincendio non tossico e non alogenato.
- Il pH neutro della superficie rende compatibile con qualsiasi sistema di catalizzatori.

This is our first order of expandable graphite for R&D purposes. The product arrived well-packaged and dry. The technical data sheet provided was accurate. We tested the expansion ratio under high heat, and it matched the manufacturer's claim closely. The flake size distribution was good. Customer service was responsive to our pre-sale inquiries. Will order again for our larger batch production.
