Flexible Elastomeric Cellular Thermal Insulation

1 1 this specification covers preformed flexible elastomeric cellular thermal insulation in sheet and tubular form.

Flexible elastomeric cellular thermal insulation.

5 3 flexible elastomeric cellular thermal insulations shall be of uniform core density and have closed cells. It is the ideal choice for insulating mechanical piping systems. First for slide on applications and second in the stresses induced on the seams of the product in applications which cycle from hot to cold and can cause expansion and contraction of the insulation up to ten percent. Grade 1 covers materials to be used on commercial or industrial systems with operating temperatures from 183 to 104 c 297 to 220 f grade 2 covers material used on industrial systems with operating temperatures from 183 to 150 c 297 to 300 f and grade 3 covers material used on industrial systems with operating temperatures from 183 to 120 c.

Even though these insulation materials may have a smooth skin surface on one or both sides they are to be considered homogeneous for. It is black in color marked in gold ink and supplied as flat sheets 36 x 48 in standard thicknesses 1 8 thru 2 in increments of 1 8 except 7 8. Electric boat corporation specification eb 4013 antisweat and refrigerant insulation systems sheets and tubes. Nh armaflex is a nonhalogen flexible elastomeric thermal insulation gray in color supplied as unslit tubing sheets and rolls sizes.

Elastomeric insulation products are more flexible have a lower modulus than polyolefin materials at 75ºf. 1 1 this specification covers preformed flexible elastomeric cellular thermal insulation in sheet and tubular form. See submittal sheet for complete size options. These gases do not change over time and the thermal conduc tivity of the insulation is stable over time.

This flexibility or modulus issue has two application implications.
