MBPA
"Combining rigidity and flexibility", bio-based eco-friendly functional materials that are both moldable and adhesive
What isMBPA
Multi-block microphase morphology copolyamide MBPA is a bio-based eco-friendly functional material; it possesses intrinsic flame retardancy, high chemical stability, excellent waterproof and dustproof capabilities, and superior resistance to high and low temperatures, making it a high-performance functional material suitable for demanding application conditions. It combines the "elastic body-like bulk" to ensure that encapsulated components can withstand stresses such as vibration and thermal expansion/contraction, with the "adhesive-like interface" to guarantee reliable connection, sealing, and moisture protection between the encapsulated assembly and its external environment. By perfectly occupying the intersectional field of "elastomeric adhesives," it represents an ideal material solution that simultaneously achieves reliable bonding and flexible protection.
KY owns proprietary core technology in the molecular structure design of "multi-block microphase morphology copolyamide base resin" (MB-CoPolyamide Base Resin), and has independently developed a vertically integrated core technology chain for synthesizing and modifying functional elastomers, specialty adhesives and coatings, and high-performance functional materials based on MBPA resin.

Advantages of MBPA
MBPA is a high-performance polymeric material designed with a multi-block microphase morphology copolyamide as its molecular backbone, achieving a balance of high mechanical strength and good flexibility within a single system, thereby resolving the traditional dilemma of polymers being either brittle when strong or weak when flexible.
The material's molecular chains exhibit an alternating block structure, providing both excellent chain mobility and the formation of physical cross-linking points and crystalline regions through intermolecular bonding. These two aspects work synergistically, complementing each other's strengths and overcoming the limitations of single-segment performance, thus endowing the material with comprehensively superior properties.
By controlling the proportion of each block, the KY technical team precisely tunes the molecular structure of MBPA to deliver outstanding performance
- Outstanding flexibility and low-temperature toughness—remains resistant to brittle fracture at low temperatures, making it well-suited for cold environments.
- Exceptional mechanical strength, modulus, and hardness, providing ample support and deformation resistance.
- Low melt viscosity and excellent flow characteristics enable low-pressure, low-temperature injection molding, protecting delicate substrates while ensuring stable and efficient forming.
- Strong adhesive performance with robust interfacial bonding, surpassing most thermoplastic encapsulation materials.
- Excellent resistance to oxidation, ultraviolet radiation, and environmental aging, ensuring long-term stability without significant degradation.
- Superior flame-retardant performance, achieving intrinsic flame retardancy: UL94 V-0 rating, self-extinguishing with no dripping, enhancing usage safety.
- Impressive chemical stability: highly resistant to acids, alkalis, organic solvents, and other chemicals, remaining dimensionally stable and uncorroded even after prolonged exposure.
- Through precise control, it exhibits low water absorption, maintaining dimensional and performance stability under varying environmental humidity levels.
