Introduction

Poron ThinStik materials are a family of lightweight, flexible polyurethane foams offered by Rogers Corporation. With a unique combination of properties, these foams are ideal for applications requiring thin, resilient cushioning and support. In this article, we will explore the key characteristics and uses of Poron ThinStik foams.

Properties of Poron ThinStik Materials

Poron ThinStik foams have the following noteworthy properties:

Low Density and High Resiliency

With densities from 0.11 to 0.31 g/cm³, Poron ThinStik foams are ultralight. The open-cell structure gives the foams excellent resiliency and recovery.

Thin Construction

These foams can be supplied in thicknesses from 0.5 mm to 6.4 mm. The thin profile makes them ideal for applications where minimal thickness is desired.

Flexibility

Poron ThinStik foams are highly flexible and conformable. They can flex, bend, compress, and recover readily under loading.

Soft Feel

The foams have a smooth, soft feel and touch. This makes them suitable for skin contact applications.

Durable

Properly laminated Poron ThinStik foams offer excellent resistance to cracking and abrasion. They provide long service life under repeated use.

Applications of Poron ThinStik Materials

Some common applications taking advantage of the unique properties of Poron ThinStik foams include:

Application	Benefits Provided
Medical Devices	Cushioning for wearable devices. Soft interface for skin contact. Conformable support with minimal thickness.
Consumer Electronics	Cushioning for slim device covers. Shock/vibration absorption. Screen/lens protection.
Sporting Goods	Padding for athletic wear and equipment. Impact absorption with minimal bulk.
Automotive Interiors	Thin, soft trim and cushioning elements. Noise dampening.

Frequently Asked Questions

Q: What types of Poron ThinStik materials are available?

A: Rogers offers several families of Poron ThinStik foams including Poron 4701-30-15505-70, Poron 4700-03-15505-73, and Poron 4000. Each provides a different balance of properties.

Q: Can Poron ThinStik foams be die cut into shapes?

A: Yes, Poron ThinStik parts can be die cut, water jet cut, laser cut, or cut using other methods. The materials are readily machinable.

Q: How should Poron ThinStik foams be bonded?

A: For most applications, the foams should be laminated to other materials using adhesives. Common adhesives include acrylics, urethanes, epoxies, and silicone. Proper surface preparation and adhesive selection is critical.

Q: What thickness range can Poron ThinStik foams be supplied in?

A: Standard thicknesses range from 0.5 mm to 6.4 mm. Custom thicknesses may be available upon request. The materials can be compressed up to 60% to achieve thinner constructions.

Q: Can Poron ThinStik foams be sterilized?

A: Yes, the materials are compatible with common sterilization methods including autoclaving, gamma radiation, and ethylene oxide.
