Compression Force Deflection (CFD) is defined as the push back force

(in psi or kPA) of the foam when compressed to a specific percentage of the

nominal thickness.

This “how can we help improve the product” philosophy

demonstrates a process of continuous improvement, as

opposed to a “just quote the job” mentality. SRP strives to make

parts using minimal waste production methods, and to deliver

product in a form that makes the most sense for a customer’s

production process. Also, customer education is a high priority,

through direct contact with expert sales engineers and regular

“lunch and learn” events.

RESULT

Rogers' PORON 92 polyurethane foam eliminated concerns the

company's reputation or end user safety would suffer as a result

of product failure. The OEM is proud to be able to offer a body-

worn gas detector that is reliable and consistent in providing

the life-saving technology protecting those who work in difficult

environments. The gas detectors are able to protect users from

injury or even death related to the inhalation of poisonous gas.

If the original PVC or neoprene gaskets had failed and workers

were injured, the company would have been at risk for

litigation. In related industries, the average cost of litigation

settlements is $217,000. The average cost of product recall is

$517,000, making Rogers' high quality PORON 92 polyurethane

foam gaskets well worth the investment.

Compression Set Resistance (CSR) is defined as the ability of a

material to resist collapse from the stresses of compression and

temperature over time.

THE ROGERS SOLUTION

For this situation, Rogers' PORON® 92 formulation provided

the best combination of softness, sealing performance, and

impact absorption properties for these gas detector designs.

The new gasket material helped the gas detectors withstand

the impact from up to a 3.7 meter (12') drop. PORON 37, 41,

and 79 formulations offer different combinations of sealing

performance, impact reduction, and compression force

deflection (see description) properties that can be used in

similar applications.

The PORON 92 foam was able to seal out dust and

moisture, reduce transmitted force from impact, maintain

its original thickness (known as compression set

resistance, see description) and provide the recompression

cycling performance needed to seal out the elements and

retain a tight seal over the longterm. SRP's design skill and

customized processing capabilities made it possible for the

OEM to use Rogers' PORON 92 foam to replace the failing

PVC sponge or neoprene blend gasket in the body-worn gas

detectors. Their multidisciplinary project team is well-trained

on the latest material technologies, allowing them to help

their customers make a better, faster, stronger, and less

expensive product.

Rogers PORON® Foam Gasket Helps Extend Lifespan of Body-Worn Gas Detectors

CUSTOMER PROBLEM

A safety device OEM and Standard Rubber Products (SRP) are committed to producing high-quality portable gas detectors. Workers

who use these devices risk their lives daily and need durable and effective protection. During pre-production testing, it was

discovered that the gasket material used to seal out dust and moisture was failing. The closed-cell neoprene blend or PVC sponge

gaskets used for different designs were soft enough and the proper density, but they were not able to retain thickness in

compression set and recompression cycling tests. In addition, some of the gas detector models were unable to meet impact

resistance requirements. As a result, the gas detectors would malfunction due to seal failure or impact damage. There was a clear

risk of worker injury, recalls, and litigation using the current design.
