Frequently Asked Questions

What is the difference between polypropylene and polyethylene?

Polypropylene has better chemical resistance, higher temperature resistance, and superior fatigue resistance compared to polyethylene. PP is also more rigid and has better clarity. Polyethylene offers better impact resistance at low temperatures. We can help you choose the right material for your application.

Can polypropylene be used for food contact?

Yes, food-grade polypropylene is FDA approved and widely used in food packaging and containers. It’s safe for hot-fill applications and can withstand microwave heating. We can source food-grade PP materials that meet FDA and EU regulations for your food-contact applications.

What tolerances can you achieve with polypropylene machining?

Our CNC machining capabilities allow us to achieve tolerances of ±0.1mm for most polypropylene parts. PP’s relatively high thermal expansion should be considered in tolerance planning. We discuss specific requirements during the design review to ensure optimal results.

Is polypropylene suitable for outdoor applications?

Standard polypropylene can degrade under UV exposure over time. For outdoor applications, we recommend UV-stabilized PP grades that contain additives to protect against sunlight. These grades maintain their properties even after prolonged outdoor exposure.

Can polypropylene be welded or bonded?

Yes, polypropylene can be welded using hot gas welding, ultrasonic welding, or vibration welding techniques. However, it’s difficult to bond with adhesives due to its low surface energy. Special surface treatments or adhesives designed for PP are required for bonding applications.

What colors are available for polypropylene?

Polypropylene is available in natural (translucent white), black, and a wide range of colors. Color masterbatches can be added during manufacturing to achieve custom colors. Availability depends on grade and order quantity. Contact us for specific color requirements.
