Data Sheet

material

A comprehensive document provided by resin manufacturers that contains detailed technical specifications, properties, processing guidelines, and performance characteristics of a plastic material or grade.

In Simple Terms

Think of a data sheet as a material's passport - it tells you everything you need to know about a plastic resin, from its strength and temperature limits to how it should be processed. Every commercial resin grade has one, and it's your first reference when selecting materials.

Why It Matters

Data sheets are critical for material selection, processing optimization, and quality control. They enable processors to match resin properties with application requirements, set proper molding parameters, and ensure consistent part performance across production runs.

Technical Details

Data sheets typically include mechanical properties (tensile strength, impact resistance), thermal properties (melting point, heat deflection temperature), rheological data (melt flow rate), processing conditions, regulatory approvals, and additive content. They follow standardized test methods like ASTM or ISO for consistency and comparability between suppliers.

Real-World Examples

HDPE blow molding grade selection

Data sheet shows density of 0.955 g/cm³, MFR of 0.3 g/10min, and ESCR properties, indicating suitability for large containers requiring stress crack resistance.

Injection molding parameter setup

Polypropylene data sheet specifies barrel temperatures of 200-240°C and melt temperature of 220°C, providing starting points for process optimization.

Material comparison for automotive parts

Comparing ABS data sheets reveals one grade has 25% higher impact strength at -20°C, making it better suited for exterior trim applications.
