Polyurethane chain extender stoichiometry: BYDRecent Research Landscape

Inconsistent mechanical properties in synthetic leather and polishing pads lead to premature wear and surface defects. Engineering the prepolymer backbone with cellulose nanocrystals and specific chain extenders stabilizes the polymer matrix for high-durability automotive and industrial applications.

What technical problems is BYD addressing in Polyurethane chain extender stoichiometry?

Interfacial adhesion failure

(55)evidences

Inadequate interfacial bonding between dissimilar materials in composite plates leads to mechanical failure and fluid bypass. Resolving these integrity issues ensures long-term durability in high-stress vehicle and filtration environments.

Inadequate polymer network crosslinking

(33)evidences

Inadequate electrical insulation and thermal instability in high-stress motor environments. Resolving these failure modes prevents short circuits and extends component lifespan in electric vehicles.

Interfacial bonding failure

(26)evidences

Weak adhesion between substrates leads to structural instability and component detachment. Improving bond strength ensures mechanical integrity in batteries and polishing pads.

Surface substrate degradation

(17)evidences

Inconsistent electron transport and poor interfacial adhesion in carbon-based layers lead to electrical resistance. Mitigating these losses ensures stable energy storage and thermal insulation performance.
