• Recycled PP (rPP): Made from post-consumer and industrial waste; used for less critical applications like automotive parts, containers.

Types of PP:

• Homopolymer PP: Offers high strength and stiffness; used in textiles, packaging.

• Copolymer PP: Enhanced impact resistance; used in automotive parts, industrial applications.

Grades:

• Injection Molding Grade

• Film Grade

• Fiber Grade

• Extrusion Grade

3. PP Uses, Applications, and Products

PP is highly versatile and used in:

• Packaging: Food containers, bottle caps, films

• Automotive: Bumpers, dashboards, battery cases
