BRAID YARNS FOR SPECIAL APPLICATIONS

EY manufactures yarns for special applications which are compounded for cold flexibility, fire resistance, and resistance to caustic fluids. Our formulations also provide abrasion resistance and a uniform surface for ease of braiding for protection of wire assemblies.

PVC has long been recognized for exceptional weathering performance, moisture resistance and abrasion resistance.

EY builds on these basic properties by compounding additives for cold flexibility, fire resistance, and resistance to engine fluids. PVC also provides abrasion resistance and a uniform surface for ease of braiding for protection of wire assemblies.
