Polyisocyanurate Foam Pipe Insulation

Polyisocyanurate for mechanical pipe insulation systems is manufactured by only 4 acceptable u s.

Polyisocyanurate foam pipe insulation.

This very rigid insulation offers the lowest heat flow rate of our pipe insulation and restricts absorption of water air and gas. Trymer pir polyisocyanurate is a closed cell foam insulation for industrial pipes vessels and equipment. The starting materials are similar to those used in polyurethane pur except that the proportion of methylene diphenyl diisocyanate mdi is higher and a polyester derived polyol is used in the reaction instead of a polyether polyol. Polyisocyanurate also referred to as pir polyiso or iso is a thermoset plastic typically produced as a foam and used as rigid thermal insulation.

Polyiso is unique in that the r value increases with the thickness of the foam so three inches of polyiso has a higher r value per inch than two inches. Suppliers two of which have considerably more credibility in the market. Trymer pir can be used in applications that operate at temperatures ranging from 297 f to 300 f 183 c to 148 c. We manufacture iso c1 polyisocyanurate as large buns and subsequently fabricate into insulation panels pipe insulation or equipment insulation.

Polyisocyanurate fabricated pipe insulation offers a greater dimensional stability over a wider service temperature range than polyurethane foam. Trymer pir polyisocyanurate is a closed cell foam insulation for industrial pipes vessels and equipment. Itw insulation that is the sole distributor of pir branded by dow chemical as trymer and dyplast products whose brand is iso c1 and iso ht for higher temperature. Additionally trymer pir is offered in a variety of different densities and compressive strengths to ensure the product consistency is suited for the unique needs of.

It is typically used in process piping and chiller plants and performs best in applications below 50 f. Trymer pir can be used in applications that operate at temperatures ranging from 297 f to 300 f 183 c to 148 c. 0 75 in x 4 ft x 8 ft. Dyplast products has the well earned reputation as the authority on low temperature pipe and mechanical insulation sheet insulation and on composite foam cores six decades of improvements in manufacturing and fabrication capabilities aggressive product development and independent certifications have led to iso c1 and iso ht polyisocyanurate insulants representing the best in class.

Polyisocyanurate foam pipe insulation. Polyisocyanurate polyiso foam is a 2 0lb ft 32kg m rigid unfaced closed cell polyisocyanurate foam supplied as shapes blocks and custom fabricated parts for use as thermal insulation. Dyplast s iso c1 polyisocyanurate rigid foam insulation line of products includes iso c1 2 0 2 lb ft3 density independently audited by factory mutual.
