Robbins Envelopes Mean Durability and Flexibility

Our unique Compression Molding Technology (CMT) uses proprietary rubber compounds, extruded into slugs and molded for curing. CMT eliminates splicing the envelope, increasing durability, flexibility, and production life.

CMT durability means:

Longer envelope life, resulting in a lower-cost-per cure
Gauge consistency for uniform envelope thickness
No splice that could result in envelope failure
Designed thickness around the valve and in the crown
Factory lubrication that extends envelope life

CMT flexibility means:

Better fit and better performance
Minimized envelope growth
Maximized damage resistance
Tear resistance from j-hooks and spreaders
Retained pliability throughout the envelope life
Superior holding pressure to keep a seal during entire curing process
