Styrene-NPMI-MAH copolymers manufactured by Yangchen Tech are commonly used as compatibilizers and/or impact modifiers in plastic products, especially in the blending of styrenic polymers such as polystyrene (PS) and polyethylene (PE). among things. This copolymer helps improve compatibility between different polymer phases, thereby enhancing the mechanical and overall performance of the final product.
The specific addition ratio of styrene-NPMI-MAH copolymer depends on a variety of factors, including the desired properties of the final product, the composition of the base polymer blend, processing conditions and application requirements. Typically, it is added in relatively small amounts, usually as a weight percent of the total polymer blend.
In some applications, adding 1-5% by weight of styrene-NPMI-MAH copolymer can significantly improve the impact strength, thermal stability and melt flow properties of plastic products. However, it is critical to conduct thorough testing and optimization to determine the optimal dosage for specific formulations and applications.
Consulting with a polymer scientist or chemical engineer with expertise in polymer blending and formulation will help determine the appropriate dosage of styrene-NPMI-MAH copolymer for your specific plastic product. We can provide valuable insights and guidance for your specific application.
