Quality control

Relevant checks defined for each material agreement

Possible checks cover material identity, consistency, process behavior, and sample approval as applicable.

Quality control

Meaningful checks, tied to the selected product

The relevant control plan is determined by material type, process, application, and customer agreement.

The checks below are possible evaluation areas, not a claim that every test is performed on every product or by an accredited laboratory. The confirmed inspection scope belongs in the product agreement.

The product agreement is the controlling reference

Final values, tolerances, sampling frequency, test methods, reporting, and approval responsibilities depend on the selected product and written customer agreement.

Possible quality checks

01

Melt Flow Index

Flow behavior checked using the method and conditions agreed for the product.

02

Density

Density evaluated where it forms part of the accepted specification.

03

Moisture limits and method defined where relevant to processing.

04

Color consistency

Visual or instrumental comparison against an agreed reference where applicable.

05

Dispersion

Distribution of relevant formulation components reviewed when required.

06

Contamination inspection

Inspection scope and acceptance criteria defined for the selected grade.

07
