Product Description

BP-5

Coace® BP-5 Chain Extender effectively extends and nucleates degradable polyester chains, speeds up cooling and forming, boosts viscosity, and improves tensile strength and puncture resistance in films and sheets.

Specification

Key Features
BP-5 is a novel multifunctional reactive chain extender meant to solve several application domains, enhance the mechanical properties, processing performance, and environmental friendliness of polyester materials, and so offer answers. By reacting with the functional groups on the linear polymer chain, the chain extender greatly increases the molecular weight, therefore enhancing the tensile strength, elongation at break and impact strength of the material. This helps the finished product to function in many demanding application contexts.

Typical Applications
Coace® BP-5 can help the chain expansion and nucleation of degradable polyester materials, accelerate the cooling and forming speed of materials, and can also be used to enhance the viscosity of polyester materials, improve the tensile strength and puncture resistance of films and sheets.
