Olefin Block Copolymers (OBCs)
Product Overview
Developed by Dow Chemical, OBCs are environmentally friendly, non-toxic, and recyclable materials.
Their molecular structure features a regular alternation of hard segments (high rigidity) and soft segments (high elasticity).
Key Properties
-
Excellent dimensional stability
-
Very low compression set
-
Outstanding heat resistance, abrasion resistance, and resilience
-
Easy processing and good workability
-
Can replace TPV, flexible PVC, EVA, some TPU grades, SEBS, SBS, and SIS depending on application needs
In Short
OBCs combine the softness of polyolefin elastomers with heat resistance close to HDPE, delivering breakthrough performance and expanding application potential.
