Industrial and Medical PORON® Foams
Rogers Corporation PORON® foams offer durable and long-term performance. This line of products meets versatile design requirements. On this page, explore the large portfolio of foam products that we offer. Marian is proud to be a world-leading manufacturer of die-cut PORON foam solutions.
Product History
Rogers Corporation, which originated in 1832, first introduced the PORON® product line in 1958 after signing an agreement with United Shoe Machinery Corporation. The foam rapidly became the leader in foam cushioning for shoe soles, a position it still holds today. By the early 1980s, Marian (then known as Marian Rubber Products) recognized the advantages of Rogers’ high density polyurethane foam in industrial applications. We have been producing custom made component parts consisting of PORON® foams ever since.
Variety of PORON® Formulations
There is not just one kind of PORON®. Rogers provides a wide variety of formulations engineered for peak performance values. This page will briefly explore some of those. Before we begin, you should know that Rogers publishes two excellent Material Selection Guides, one for industrial grade and one for medical grade.

Outstanding Performance Characteristics of PORON® Foam
- Excellent compression set resistance
- Micro-cellular open cell structure
- Good chemical resistance
- Flame retardant to UL 94 (The UL rating varies by grade and thickness. See the Guide for details.)
- Environmentally safe, low outgassing
- Durable and long-term performance
- Achieves a strong bond to Pressure Sensitive Adhesive (Let us help you with this selection.)
- Thickness – All are “cast to thickness” (rather than skived like many other foams) and are readily available in a wide range of standard thicknesses. However, materials can also be made to order in a custom thickness (minimum quantities will apply).
- We can supply very thin versions cast to a thin layer of polyester for dimensional stability.
- Color – Typically, the industrial grades are available in black color as standard. Some other colors are made to order with minimum requirements. Ask your Marian sales engineer or customer service rep for more details if you need a color other than black.
- Can be laminated, die-cut, laser cut, water jet cut, and slit with precision. (That is where we come in!)

PORON® Medical Polyurethane Products
PORON® medical grade foams share the same outstanding benefits that we discussed above regarding the industrial grades with the added feature that they have increased resistance to microbial growth, fungal resistance. This makes them well suited for cushioning, support, and comfort in orthopedic and prosthetic devices or any equipment involving skin contact. These materials are breathable, durable, and long lasting.
PORON® Medical Polyurethanes are divided into four groups.
