Are reinforced PP grades available?

Yes. Glass-filled PP provides enhanced stiffness and strength for demanding applications.

Is PP suitable for high-precision machining?

PP is softer than many plastics, but CNC machining can achieve accurate dimensions with proper tooling.

What industries benefit from PP parts?

Automotive, packaging, laboratory, and c onsumer goods industries frequently specify PP.

Can PP withstand chemicals and solvents?

Yes. PP has strong resistance to many acids, bases, and solvents, making it suitable for lab and chemical equipment.

Why is PP widely used in industrial parts?

PP provides excellent fatigue resistance, c hemical resistance, and low cost, making it ideal for functional components.
