MATERIAL

PP Polypropylene Case

PP is chemical-resistant, food-safe, and ideal for medical/lab applications.

Polypropylene and other engineering plastic samples

Polypropylene (PP) is the lightest and most chemical-resistant of the three common case materials. It is the material of choice for medical, food, and laboratory cases.

Why This Case Study Matters

PP (Polypropylene) plastic cases are the industry standard for chemical-resistant protective cases. PP is a thermoplastic polymer with excellent chemical resistance (resists most acids, bases, and solvents) and good low-temperature performance (stays flexible to -30 C). Key properties: impact strength (Izod 50-150 J/m), tensile strength (25-35 MPa), temperature range (-20 to +100 C), UV resistance (good with stabilizer), chemical resistance (excellent). PP is widely used in marine, medical, and food-contact cases. For B2B buyers, PP is the best choice when chemical resistance, low-temperature performance, and cost-effectiveness are priorities. PP is widely recyclable (code 5) and has lower environmental impact than ABS. Tooling cost: $5,000-15,000 for injection molds. Cycle time: 45-120 seconds. Per-unit cost: $15-100.
