Compatibilizer/chain extender for degradable materials
BP-5 is a highly efficient chain extender for biodegradable plastics. With an extremely low addition amount of 0.2%-0.5%, the melt index of biodegradable materials can be effectively reduced.
Chain extenders are typically used to increase the molecular weight of a polymer by reacting with the polymer's functional groups. This can lead to improved mechanical properties, such as increased strength and toughness, as well as improved processability.
In the case of degradable materials, such as biodegradable plastics, chain extenders like BP-5 can help to improve their properties and make them more suitable for a wider range of applications. For example, by improving the tensile strength of a degradable material, it may be possible to use it in applications where it needs to withstand more stress or strain, such as packaging materials or agricultural films.
It's also worth noting that the use of chain extenders like BP-5 in degradable materials may help to improve their overall sustainability by allowing them to be used in a wider range of applications and potentially reducing waste.
BP-5 is a chain extender for degradable materials, which can expand the length of molecular chains and improve the tensile strength of materials.
BP-5 is a chain extender and nucleating agent for degradable polyester materials, which can accelerate the cooling and molding speed of materials.
