Open-cell Reticulated NPWT

Negative Pressure Wound Therapy (NPWT)

WITP Medical Foams are processed using medical procedures to ensure quality product with each lot. Using our advanced processing capabilities, the foams can be provided in multiple formats including bun stock, rolled goods and die cut shapes. Our in-house lamination allows for the development of multi-layered composites using foams and fabrics. Our standard medical foams have been tested to meet ISO 10993 biocompatibility standards.
