For a foam solution that is soft to the touch yet still offers incredible durability, our Volara Type 4EO foam is the perfect solution. This EVA copolymer foam is ideal for use in medical devices and applications designed for skin contact thanks to the overall nature of the material. In addition to these applications, Volara Type 4EO foam contains FDA compliant materials. This fact alone makes this product acceptable for food contact further expanding the possible applications of this versatile solution. Another great feature of this foam type is that this product will thermoform and can be compression molded for even more versatility. Our high-quality Volara Type 4EO foam can also be utilized as a substrate for double-sided foam tape applications.
