PVC Manufacturing and Processing

Introduction

Polyvinyl chloride (PVC), a synthetic resin made from the polymerization of vinyl chloride. Second, only to polyethylene among the plastics in production and consumption, PVC is used in an enormous range of domestic and industrial products, from raincoats and shower curtains to window frames and indoor plumbing. A lightweight, rigid plastic in its pure form, it is also manufactured in a flexible “plasticized” form.

Objectives

    • Exercise proper pipefitting safety procedures
    • Compare the types of plastic piping and assess the advantages and disadvantages of each
    • Install, maintain, and troubleshoot plastic and fiberglass-reinforced piping.

Training Methodology

The program design includes a high level of interaction between the trainer and the participants. It is built upon the participants input all throughout the program.

Who Should Attend?

This program is specially designed for department heads, chemists, and engineers who are involved in the manufacturing, processing, and quality control of PVC.
