Material Classification & Grade

Specify the exact polystyrene type and grade required for your application. Include molecular weight, melt flow index range, and any special additives or modifiers. Reference ASTM D4549 for PS classification standards.

Physical & Mechanical Properties

Define critical performance parameters including tensile strength, impact resistance, density, and thermal properties. For HIPS, specify minimum Izod impact values. For foam grades, include density reduction ratios and cell structure requirements.

Processing Requirements

Specify processing temperature ranges, moisture content limits, and recommended processing conditions. Include drying requirements and any special handling procedures for volatile styrene monomer containment.

Application-Specific Requirements

Define end-use requirements such as food contact compliance (FDA 21 CFR 177.1640), flame retardancy for construction applications, or specific insulation R-values for XPS. Include any regulatory compliance needs.

Quality Control & Testing

Establish testing protocols and acceptance criteria. Reference ASTM D638 for tensile testing, ASTM D256 for impact testing, and ASTM D792 for density measurements. Include certificate of analysis requirements.

Packaging & Delivery Specifications

Specify packaging requirements including bag size, pellet form, and contamination prevention measures. Include delivery timeline expectations and storage conditions to prevent styrene monomer loss.
