PolyBlend 1100™ 45A
TPU Alloy
AdvanSource Biomaterials(美国ASB)
产品描述
PolyBlend is a family of exceptionally soft, aromatic polyurethane elastomeric alloys, which can be used as a substitute for natural rubber or latex in many applications.
These polymers encompass unique characteristics such as low flexural modulus, moderate tensile strength, and high elongation, in addition to allowing for a high draw-down ratio due to its superior melt strength and chemical integrity.
PolyBlend can be processed on conventional extrusion or injection molding equipment and is available in hardnesses ranging from 45 Shore A to 80 Shore A.
