Quality Assurance

Documented quality from incoming materials through batch release and COA issuance.

CONTROLLED SYSTEM

Repeatability through defined process, data and accountability

The control plan is based on approved product specification, test method, sampling frequency, acceptance limits and nonconformity response.

Depending on the grade, testing may include MFR/MVR, density, tensile, flexural, impact, Vicat/HDT, color and moisture.

A COA is issued only from actual batch results, while material, production, test and packaging records are retained for traceability.
