产品描述
Polypropylene 3727W strikes an optimum balance between excellent mechanical properties (tensile, flex and impact) and processability making it a superior molding grade for cap and closure applications.
Impact Strength. 3727W offers improved impact strength.
Nucleation. 3727W is formulated to provide fast cycle time and improve contact clarity in thin wall multi-cavity molds.
Regulatory. 3727W has passed USP Class VI testing, and all ingredients meet the chemical registration requirements of TSCA (U.S.) and DSL (Canada). TOTAL Polypropylene 3727W complies with all applicable FDA regulations for food contact applications.
Recommended Application. 3727W is recommended for large thin wall parts, caps and closures.
Processing. 3727W resin processes on conventional injection molding equipment with typical melt temperatures of 390°F-450°F (200°C-232°C).
