This book focuses on the additives currently important in the polyolefins industry, and on new additives of increasing interest, such as nanofillers and environmentally sustainable materials. Each chapter emphasizes the performance of the additives in the polymer, and the value each relevant additive brings to polypropylene or polyethylene. Where possible, similar additives are compared in terms of capability and relative cost.

With major sections for each additive function, this book provides a wealth of detail and practical guidance for engineers and scientists creating and using polyolefin compounds. A number of short case studies discuss companies that have used or developed a particular additive to achieve a desired result. The book’s structure also makes it easy to find solutions for specific property requirements, which business managers may find helpful in determining how the additives can be used to cut costs or expand markets.
