Understanding Chlorinated Paraffin Wax (CPW) Grades – A1 to H5: Your Complete Guide
Overview of CPW Grades"

💡 What is CPW and Why Does it Matter?
Choosing the right Chlorinated Paraffin Wax (CPW) grade isn’t just a technical decision — it directly impacts product performance, compliance, and manufacturing efficiency. At Suntek, we understand that every industry has unique demands. That’s why we’ve developed a range of CPW grades — from A1 to A5 for standard performance, to H1 to H5 for high-performance applications.
In this guide, we break down each CPW grade by its chlorine content, viscosity, and industrial use case — helping you make confident, informed decisions. Whether you’re in PVC, rubber, paints, flooring, or flame-retardant manufacturing, there’s a perfect grade waiting for you.
Let’s explore what makes Suntek’s CPW range the most trusted in the industry.
Understanding the Different CPW Grades – A1 to A5 and H1 to H5
Suntek offers A-series CPW grades, designed for general-use across a variety of industries. These grades provide balanced performance, making them perfect for a range of applications.
CPW Grades A1 to A5 – Standard Performance for General Applications
Chlorine Content: 42% to 68%
Viscosity: 1 to 700 Poise
Common Applications:
PVC Cables
Paints
Flooring
Rubber
The A-series CPW grades are the go-to choice for general applications that don’t require extreme performance. These grades offer excellent flexibility, chemical resistance, and durability.

For industries that demand higher performance, Suntek’s H-series CPW grades are your best bet. These grades come with increased viscosity and better thermal stability, making them ideal for demanding applications.
CPW Grades H1 to H5 – High-Performance Solutions for Demanding Applications
Chlorine Content: 42% to 68%
Viscosity: 500 to 2000 Poise
Applications:
Flame-Retardant Solutions
High-Temperature Environments
Specialized Industrial Uses
The H-series CPW grades are designed for applications that need enhanced heat resistance and better performance in extreme conditions. These grades are commonly used for high-temperature environments and flame-retardant applications.

Quick CPW Grades Comparison – A1 to H5: Find the Best Fit for Your Needs
