Many potential APET sheet applications do not require the physical properties of the high IV resins.
Other copolymers are under development to provide a range of melting temperatures and crystallization behaviors that can be used to tailor structures to meet specific needs in the APET market.
The crystallization behavior of the resin is important in APET sheet production and thermoforming.
HMV polyesters offer the range of crystallinity behavior needed for a variety of APET applications.
The extruder conditions for the HMV polyesters are much the same as with other APET resins used for sheet but less demanding than those required for PETG, another amorphous polymer.
HMV APET resins have created new possibilities for the sheet producer.
The HMV APET sheet is easily thermoformed using vacuum, pressure, and plug-assist methods.
