PET Resin
PET Resin
PET resin is a polymer manufactured from terephthalic acid (PTA), isophthalic acid (IPA) and ethylene glycol (EG) raw materials.
SASA included the bottle-type PET Resin product group in its portfolio with the new MTR (Melt to Resin) facility with a capacity of 315 kt/year, commissioned in 2020. Thanks to the MTR technology, unlike the traditional two-stage method, bottle-type PET Resin manufacturing obtains a high viscosity product at the desired level with a single-stage process.

Advantages:
SASA PET Resin is a high-performance, user-friendly product thanks to its MTR (Melt to Resin) manufacturing technology. After the polymerization, the chips, which are granulated in underwater chips cutting units, take a spherical form. This spherical form offers users several benefits such as:
- Low energy consumption, low carbon emission
- Low dust content
- Homogeneous IV distribution
- Low acetaldehyde formation
- Easier flow, less dust formation compared to cylindrical form
Main Applications:
- PET bottles; carbonated and still mineral waters, soft drinks, oils
- PET containers; Food, Detergent, Cosmetic, Pharmaceutical
- PET Thermoforms
- PET Sheets
