When designing PET blends, the following factors should be considered:
Performance Requirements: Determine specific properties required, such as mechanical strength, heat resistance, chemical resistance, or flexibility.
Processing Compatibility: Ensure compatibility between PET and blend polymer to optimize processing conditions and achieve desired material properties.
Application Specificity: Tailor the mix to the exact requirements of the application, taking into account environmental conditions and end-use performance.
Cost-effectiveness: Evaluate the cost-effectiveness of blending compared to using pure PET or alternative materials.
Polyethylene terephthalate (PET) processing methods
Manufacturers process polyethylene terephthalate (PET) into various products using several distinct methods suited to different applications:
Cast iron spinning
In melt spinning, PET resin is melted and extruded through spinnerets to form continuous filaments. These filaments are then stretched to align the polymer chains, which increases their strength and crystallinity.
The textile industry relies heavily on this process, using PET fibers to create polyester fabri
