Physical Properties
Insulation: Polyisocyanurate (Trymer Foam Insulation) Jacket: Special purpose rigid PVC extrusion compound Complies with the ASTM E 84-05 Standard Test Method for surface burning characteristics of materials.
Mechanical Pipe Shields recommends Rigid Polyisocyanurate insulation. They are a user friendly product. They are cleaner and have several advantages over Calcium Silicate. In most cases the Trymer Urethane has adequate compressive strength to meet the requirements of weight bearing loads at the hanger point. The following outlines the characteristics of the Trymer Foam Insulation:
Trymer 2000 - Urethane has the following characteristics:
- Compressive Strength = 24 p.s.i. average
- Flexural Strength = 44 p.s.i. average
- K Factor = .190 @ 75 degree F - aged 180 days
- Working Temperature Range = -297 degree F to +300 degree F
- Trymer 2000 insulation is used for 1/2 inch wall thickness insulation inserts.
Trymer 4000 - Urethane has the following characteristics:
- Compressive Strength = 80 p.s.i. average
- Flexural Strength = 44 p.s.i. average
- K Factor = .190 @ 75 degree F - aged 180 days
- Working Temperature Range = -297 degree F to +300 degree F
Insul-Phen - Phenolic Foam has the following characteristics:
- Compressive Strength = 3.75 54 p.s.i. average
- K Factor = .16 @ 250 degree F—aged 7 days
- Working Temperature Range = -290° F to =250°F
Trymer is used for 1/2" and 1" wall size. Insul-Phen density is used for over 1" wall thickness size.
