Adhesive Resin PB is a subcategory of Polybutylene. It is specially formulated to adhesive resin. Its elastic modulus ranges from 10 to 15 MPa.

Polybutylene, also known as PB, is a thermoplastic polymer. Common trade names are Shell and Mitsui. It has high flexibility (even at low temperatures), a low embrittlement temperature, high toughness, high abrasion resistance, high resistance to chemical attack, and resistance to hot water and stress cracking. It has poor handling properties in the forms of semi-finished goods and moldings after processing because of the start of crystal rearrangement. PB can be used to make tubes, sheets, and profile extrusions by extrusion blow molding and/or injection molding.
Additional Information
Other common Polybutylene (PB) include Extrusion Compound PB, and Film Grades PB.
