THE ROGERS SOLUTION

Rogers PORON 30-

15 urethane materials were

used to fix the seal on the door of the furnace

even though the door was accessed often for

repairs and maintenance. PORON resists

compression set (see description)which allows it

to maintain a seal over a long period of time,

providing consistent sealing force for the access

door.

In addition, Rogers offers color

differentiation that can make assembly easier.

RESULT

With

Rogers PORON urethane foam, the furnace

manufacturer provided a gasket that maintained its

seal and resisted compression set, ensuring a

consistent result over time. This reduced the

rattling noise the previous failed gasket produced

and gave the customer peace of mind, reducing

labor and replacement part costs for the

manufacturer.

pression Set Resistance (CSR) is defined as the ability of a material to resist collapse from the stresses of

compression and temperature over time. What does it do? A material with high CSR extends the life of a product by sealing out dust and

light while absorbing shock and maintaining constant spring forces.

APPLICATION SUCCESS STORY

Rogers and Furnace Company

Solve Access Door Rattling Issue

Rogers PORON®30-15 Urethane Gasket Resists Furnace Heat and Maintains Seal

CUSTOMER PROBLEM

Furnaces are a staple of everyday life. When a customer hears rattling in their furnace, it is fodder for worry,

especially if they live in colder climates. A major furnace company was experiencing gasket failure because

their gasket material was ripping and losing the seal on the access door maintenance workers regularly used

to repair the furnace. This resulted in a rattling noise when the furnace would activate and caused many

customers to think the furnace was malfunctioning, producing higher labor and repair costs for the furnace

manufacturer.
