PET Preform Unstable Injection Cycle

Cycle = system stability.

Material Drying PET; preform; cycle; plasticization; temperature control

PET Preform Recycled Material Utilization

Preform reuse = ratio + drying + IV monitoring.

Material Drying PET; preform; recycling; IV; drying

PET Bottle Drop Rupture

Material Drying PET; bottle blowing; drop; rupture; embrittlement; bottom

PET Preform Missing Moisture Verification

Intermittent haze = drying system state drift.

Material Drying PET; drying; dew point; molecular sieve; dehumidification

PET Sheet Extrusion Bubbles

Bubbles = drying dew point.

Material Drying PET; sheet; bubble; drying; dew point

PET Sheet Extrusion Crystallization Haze

Sheet haze = cooling rate and moisture.

Material Drying PET; sheet; extrusion; crystallization; chill roll

PET Preform IV Drop (Intrinsic Viscosity Decrease)

IV is the general ledger of PET processing quality.

Material Drying PET; IV drop; intrinsic viscosity; hydrolysis; thermal degradation

PET Preform Acetaldehyde (AA) Odor

Odor = degradation products; dual control of temperature and water.

Material Drying PET; acetaldehyde; odor; thermal degradation; hydrolysis

PET Preform Excessive Drying Crystallization

Drying is not the longer the better; over-drying = pre-crystallization.

Material Drying PET; preform; excessive drying; crystallization; white haze

PET Preform Insufficient Drying (Hydrolysis)

Material Drying PET; preform; drying; hydrolysis; white haze
