Overview
PP3155E5 is a specialized grade of polypropylene copolymer engineered for enhanced mechanical properties and processing characteristics. As a thermoplastic polymer, it offers an excellent balance of stiffness and impact resistance, making it suitable for demanding industrial applications. The material is particularly valued in injection molding applications where consistent flow properties and dimensional stability are required. Its copolymer structure provides improved low-temperature toughness compared to standard polypropylene homopolymers.
Physical and Chemical Properties
PP3155E5 exhibits typical polypropylene characteristics with specific enhancements. It has a density of about 0.905 g/cm³ and melts between 160-165°C, with good thermal stability during processing. The material shows excellent resistance to acids, alkalis, and most organic solvents. Mechanically, this grade offers superior impact strength, especially at lower temperatures, while maintaining adequate stiffness. Its moisture absorption is negligible (<0.01% at 23°C), making it dimensionally stable in humid environments. The material has a high dielectric strength and good electrical insulation properties.
Main Applications
The primary use of PP3155E5 is in automotive components, particularly interior trim parts, glove boxes, and air ducting systems where impact resistance is crucial. Its balance of properties also makes it suitable for thin-walled packaging applications and consumer product housings. In industrial settings, PP3155E5 is commonly processed into storage containers, pallets, and material handling equipment. The medical industry utilizes this material for non-critical disposable items where chemical resistance and sterilizability are required. Recent developments have seen increased adoption in 3D printing filaments for functional prototypes.
Safety and Storage
PP3155E5 is classified as non-hazardous under normal handling conditions. However, molten polymer can cause thermal burns, and processing emissions should be controlled with adequate ventilation. The material is not known to release hazardous decomposition products below 300°C. For storage, PP3155E5 pellets should be kept in their original packaging in a dry environment below 40°C. Extended exposure to UV radiation should be avoided as it may affect material properties. Shelf life is typically 12 months when stored properly, though material testing is recommended for critical applications after long storage periods.
B2B Procurement Guide
When sourcing PP3155E5, buyers should verify the material's melt flow rate (MFR), typically in the range of 10-20 g/10 min (230°C/2.16 kg), to ensure compatibility with intended processing methods. Impact strength specifications, particularly at low temperatures (-20°C to 0°C), are critical for automotive applications. Procurement professionals should request certification of analysis (CoA) for each batch, including testing for key mechanical properties and additive content. Consider ordering trial quantities for process validation before large-scale purchases. Lead times for specialty grades may vary from 4-8 weeks, so advance planning is recommended for production continuity.
