For PP S2040, the following processing parameters are recommended to ensure optimal product quality:
Drying: Although PP has extremely low hygroscopicity, in high-humidity environments, drying at 80°C for 1-2 hours is recommended to improve product surface gloss.
Melt Temp Range: Set between 200°C – 230°C. Utilizing its high flowability, rapid mold filling can be achieved at lower pressures.
Mold Temp: Maintain between 30°C – 50°C. Lower mold temperatures help speed up the molding process and shorten the production cycle.
Professional Tip: It is recommended to use high-precision dehumidifying dryers and regularly check temperature sensors to prevent material degradation caused by local overheating.
In global trade, compliance is our core competitiveness.
Authority Certificate List: Our products fully comply with REACH and RoHS environmental regulations. For medical or food-grade applications, corresponding FDA food contact compliance statements can be provided.
Batch Stability: ZiJun Plastics has established a complete quality traceability system with the manufacturer. Every batch of PP S2040 undergoes laboratory testing for melt index and impurities before storage to ensure every bag meets TDS indicators.
Export Compliance: We are familiar with the customs clearance procedures of major global ports and can provide a complete COA (Certificate of Analysis) report to safeguard your global procurement.
