Airtech fabrics NW 339 & NW 339HA are non-woven polyester fabrics which can be used for higher pressure cures. These breathers still have elongation and cushion any sharp radius for vacuum bag protection. Non-woven construction provides good conformity. NW 3390HA is a high airflow fabric which will provide better airflow and vacuum levels during higher pressure cures.
• Better breather performance reduces trapped volatiles in autoclave cures.
• Can protect vacuum bag from puncture by sharp tooling details.
• Highly absorbent make it ideal for resin bleed out applications.
