The high density of PET foam gives it greater structural strength and durability. High-density PET foam has higher compressive strength and stiffness than low-density foam, making it more suitable for applications requiring higher mechanical properties.
High-density PET foam also has other excellent properties, such as excellent flame retardancy, chemical stability and weather resistance. These properties allow it to perform well in a variety of environmental conditions and can be used to manufacture products that require a high degree of reliability and durability.
