OBC can be fully miscible with small amount of UHMWPE while phase separation occurs when the content of UHMWPE is large. Small addition of UHMWPE favors increased tie-effect. Increased tie-effect is helpful to the elasticity retaining as well as strength enhancement. Large addition of UHMWPE gives rise to phase separation and mixed shish-kebabs, leading to elastomer-to-plastic transition.
