The minimum wall thickness for polypropylene (PP) components largely depends on the application, molding process, and part design. Generally, for injection-molded PP, a minimum wall thickness of 0.8mm to 2.5mm is typical. This range accounts for a balance between strength, flexibility, and efficient processing. Thin walls are desirable for reducing material usage and cycle time, but too thin may lead to defects or compromised structural integrity. For specific applications, considering the mechanical requirements and environmental conditions is crucial. Adjusting wall thickness might be necessary to meet particular strength or durability needs. Additionally, uniform wall thickness is recommended to minimize stress concentrations and warping.

Although widely considered safe for use in non-ingested products such as cosmetics or sunscreens. the safety of titanium dioxide is uncertain when inhaled or ingested. The European Food Safety Authority EFSA recently conducted a reassessment of food safety and determined that titanium dioxide can no longer be deemed a safe food additive. This conclusion was reached due to concerns about genotoxicity and overall uncertainty regarding its effects on human health. Medical organizations globally are actively studying and monitoring these effects. With this in mind. it is advisable to consult with your physician or healthcare provider before incorporating any new treatments or substances. including titanium dioxide.

Polypropylene (PP) is a thermoplastic polymer used extensively in packaging, textiles, automotive parts, and reusable containers. It is known for its versatility, resistance to chemicals, elasticity, and toughness. PP is favored for its ability to be easily molded and its recyclability, making it an environmentally friendlier option compared to other plastics. Its low cost and ability to act as a barrier against moisture also contribute to its popularity in various industries. Moreover, PP can be copolymerized (modified with other polymers) to enhance its properties for specific applications, such as increasing its impact resistance or flexibility. This adaptability makes it invaluable for innovation in product development and sustainability efforts.
