Performance Characteristics
- Processability. Due to its good melt flowability and processing stability, Marlex HGX-030SP is easy to process by injection molding, extrusion, blow molding and other processing methods, and is suitable for large-scale production.
- Molding shrinkage. Low and stable molding shrinkage helps control product dimensional accuracy and reduce scrap rate.
- Chemical resistance. Polypropylene material itself has good resistance to a variety of chemicals, and PP HGX-030SP is no exception, which makes it suitable for occasions where it comes into contact with a variety of chemicals.
- Heat resistance. According to the characteristics of polypropylene material, Marlex HGX-030SP should have a high heat deformation temperature and be able to maintain the stability of shape and performance under certain high temperature environments.
- Weather resistance. Since HGX-030SP is resistant to gas fading, it shows that the resin can still maintain bright color and stable performance when exposed to environmental factors such as sunlight and oxygen.
- Food contact compliance. The resin meets food contact requirements and can be used in products that come into direct contact with food.
