- Biodegradability: The main attraction of this product is its biodegradable character. The demand for environmentally friendly materials is critical as the planet shifts towards more sustainable living. Naturally breaking down this chain extender helps polyester products have less environmental impact.
- Reactivity: Being a reactive chain extender, it enhances the molecular weight of polyester, therefore improving its mechanical qualities. In uses when durability and strength are non-negotiable, this reactivity is absolutely vital.
- Powder Form: The powder form of this chain extender presents simplicity of handling and incorporation into industrial processes. It guarantees consistent distribution and best performance by being readily combined with other elements.
- Improve mechanical properties: By means of the combined effects of chain extension and nucleation, the material’s toughness, elasticity, tear resistance, and overall physical and chemical properties including temperature resistance, oil resistance, weather resistance, and corrosion resistance are much enhanced.
- Chain extension: Reaction with the functional groups on the linear polymer chain results in a longer molecular chain, therefore raising the molecular weight, strengthening the melt strength and viscosity of the material.
- Nucleation: As a nucleating agent, it can notably raise the crystallinity of polymer goods and enhance their gloss and transparency.
- Improve compatibility: Improve compatibility between several polycondensate materials such that the material performs generally better.
Advantage
Enhanced Properties: Acting as a chain extender helps polyester products to have far better tensile strength, impact resistance, and general durability. In sectors where performance is first priority, this is a major benefit.
Sustainability: This product’s biodegradability fits the worldwide movement towards using green substitutes and lowering plastic waste. This not only improves the surroundings but also helps businesses using sustainable policies to have better brand image.
Cost-Effectiveness: This chain extender presents a reasonably priced alternative even if it offers exceptional performance. The better qualities of the polyester help to lower the demand for extra reinforcements, so saving material expenses.
Regulatory Compliance: This solution provides a compatible substitute as more laws control the usage of non-biodegradable products. It guarantees producers a clear road to market by meeting the strict criteria established by environmental protection authorities.

Application
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.
Application industry
Industry for polyurethanes: Chain extenders are absolutely essential key additives for polyurethane adhesives and sealants since they directly influence the mechanical qualities and process performance of the products.
By chains extension and nucleation, polyurethane foam increases the mechanical strength and durability of foam products.
The sector of plastic goods: Engineering polymers such PBT (polybutylene terephthalate) have notable impacts in raising viscosity and modification.
Recycled plastics treated with chain extenders show much better mechanical qualities and processing stability.
Automotive Industry: Adding chain exteners to textile fibres will greatly increase their strength and wear resistance and be appropriate for the manufacture of luxury clothes textiles.
achieveive: Through chain extender treatment, construction plastics—such as PVC pipes, door and window frames, etc.—can considerably increase their mechanical strength and weather resistance.
