WANKAI” Brand ‘WK851″ PET resin bottle grade is TPA-based polyethylene terephthalic copolymer. It is a high molecular weight polymer giving enhanced properties for reheat blow stage of bottle production.
Keeping the similar properties of WK881, it is characterized by lower energy consumption but higher production rate during bottle production. Because of the additive,it looks darker, but the final bottle keeps the clarity as WK881’s.
The following table provides the parameters that characterize the grade.
| Parameter | Unit | Value | Limits |
| Intrinsic Viscosity (Foreign Trade)(I.V.) | dl/g | 0.875 | ±0.02 |
| Acetaldehyde Content | ppm | 1 | Max |
| Color（L-value） | — | 72 | Min |
| Color（B-value） | — | -0.5 | Max |
| Melting point | ℃ | 243 | ±2 |
| Moisture Content | wt% | 0.4 | Max |
