The flame-retardant mechanism of flame-retardant PP (polypropylene) materials centers on interrupting or delaying the “heat-oxygen-combustible gas” cycle (the three essential elements of combustion: combustibles, oxidizers, and ignition sources) through physical or chemical actions. Based on the types of flame retardants used…

The future research directions of flame-retardant PP (polypropylene) materials mainly focus on the following aspects:

PP (Polypropylene) has a symmetrical molecular structure with no polar groups, resulting in extremely low surface energy (about 29-30 mN/m). This is far lower than the surface energy required by inks, adhesives, and other bonding substances (usually ≥38 mN/m), making…

PP (Polypropylene) is a widely used plastic—light, strong, and low-cost. But its smooth, non-polar surface makes it hard for inks, glues, or coatings to stick. To fix this, surface treatments are key. But which one works best for better adhesion?…

PP (Polypropylene) is a popular plastic material used in packaging, toys, and household items because it is lightweight and durable. But many people wonder: how long can the printing on processed PP stay clear and intact? The answer depends on…

PP (polypropylene) is widely used in packaging and label printing for its good performance and low cost. However, its low surface energy and polarity limit ink adhesion. Pretreatment boosts surface energy, but ink type still greatly affects printing durability.​ Solvent-Based…
