Description

Butene, Polymer With Ethene is a copolymer primarily composed of butene and ethene (ethylene) monomers. This material is valued for its ability to modify the physical and mechanical properties of base polymers, offering enhanced flexibility, impact resistance, and processability. It is a critical component for manufacturers in the plastics and polymer industries seeking to engineer materials with specific performance characteristics for demanding applications.

Application

• As a modifier and impact improver in polyolefin blends, particularly polypropylene (PP) and polyethylene (PE).
• In the production of flexible packaging films to enhance toughness and tear resistance.
• For manufacturing automotive components such as bumpers, interior trim, and under-the-hood parts requiring durability.
• As a key ingredient in wire and cable insulation and jacketing compounds to improve flexibility and environmental stress crack resistance.
• In the formulation of adhesives, sealants, and coatings to adjust viscosity and elastic properties.
• For the modification of thermoplastic elastomers (TPEs) and other specialty polymer compounds.
