Product Description
Chain extender BX ADR 4300 is a polymeric epoxy functional chain extender. The epoxy functional groups in its structure can achieve chain extension of the polymer by reacting with the terminal light groups, hydroxyl groups and amino groups in the resin to improve the resin characteristics, viscosity, mechanical properties. and the purpose of inhibiting polymer hydrolysis can be used in food contact materials.
Key Applications
Chain Extender in RPET
Epoxy chain extenders play a crucial role in recycled PET(RPET) by restoring molecular weight and enhancing mechanical properties such as tensile strength and impact resistance. They improve processability during manufacturing and enhance compatibility in polymer blends, making recycled PET suitable for high-performance applications like packaging, textiles, and automotive components. This results in recycled PET performing similarly to virgin PET, thus promoting sustainability and expanding its application range.
Chain Extender in PLA/PBAT
Epoxy chain extenders play a crucial role in enhancing the properties of PLA (polylactic acid) and PBAT (polybutylene adipate-terephthalate) blends. They react with the chemical groups of these polymers, increasing molecular weight and improving mechanical properties like tensile strength and flexibility. This results in better processability during manufacturing and improved performance in final products. Epoxy chain extenders also enhance the compatibility between PLA and PBAT, creating more homogeneous blends that exhibit superior overall properties, making them suitable for applications such as packaging and biodegradable materials.
