SEWING THREADS FIREPROOF

CLASSIFICATION OF IGNITURE MATERIALS

 

When dealing with a topic as delicate as fireproof sewing threads resistant to fire and high temperatures we must make a first classification to clearly define the properties of each thread and know what we can expect from them.

Classification Temperature Material Brand Hicoman
Non-flammable 1200ºC Sílice SILICAN
on-flammable 1000º CSteel + P-aramida KEVLAR SS
Inflamable 550ºC Vidrio + PTEE GLASCORE
Non-flammable 275ºC PTFE SUNLAST
Flame retardant 425ºC P-aramida KEVLAR
Flame retardant 370ºC M-aramida NOMEX ARX

Our entire range of sewing threadsfireproof are heat resistant, meaning that the wires do not lose their properties while the temperature increases.

 

This property is inherent and comes from its own chemical nature, so it is not lost with the passage of time or its repeated use.

 

Inflammable: adj. It can not ignite or can not burn with flame.

 

Flame retardant  : adj. It protects against fire.
