Use of fabrics greatly improves an inflatable profile's inflation pressure. Higher inflation pressures are required when sealing against high pressure differentials or to exert clamping/actuating forces greater than normal. The fabrics we offer are an integral part of each Pneuma-Seal through a very unique molding process. Types or fabrics vary between profiles. As an example, due to Kevlar's thickness, we are unable to supply this reinforcement in some of the smaller inflatable profiles. Please contact Pawling for details.

Nylon

A high tenacity yarn that is tough and abrasion-resistant. Nylon is the most common fabric used in our inflatable products, because it is strong and pliant thereby enabling our products to dynamically inflate and deflate. Nylon is a cost effective alternative to other fabrics.

Dacron^® Brand Polyester

Dacron is another high tenacity, high modulus yarn used primarily when high flexibility is required. Dacron can be used with silicone and organic polymers and is especially effective in applications where heat > 250°F is present.

Nomex^® Brand Aramid

Nomex is one step above Dacron in its ability to withstand temperatures and chemicals. Nomex is often used in conjunction with silicone as both materials are able to withstand temperatures > 250°F.

Kevlar^® Brand Aramid

Kevlar is the by far the strongest fabric Pawling uses. It is temperature-resistant, tough, and has a high modulus. Kevlar can only be used in larger cross sections due to its thickness and its high cost needs to be weighed against the benefits provided.
